28 Installation 4.6 Connecting the motor at the terminal box 4.6 Connecting the motor at the terminal box General information on motor connection DANGER Any work may only be carried out when the machine is stationary, isolated from the power supply and secured so that it cannot be switched back on again. This also applies to auxiliary circuits, e.g. anti-condensation heating. Check that the unit is in a no-voltage condition. If the line supply manifests any deviations from the rated values in terms of voltage, frequency, curve form or symmetry, such deviations will increase the temperature and influence the electromagnetic compatibility. Before starting work, make sure that a protective conductor is securely connected. Connect the motor in such a way that a permanently safe electrical connection is ensured. Wire ends must not protrude. Use matching cable end pieces. Connect the line supply voltage in the terminal box. Arrange the disconnecting link according to the circuit diagram for star or delta connection in the terminal box. Select the connection cables according to DIN VDE Take into account the rated current and the plant-specific conditions. The following required information for connection is specified in the technical data: Direction of rotation Number and arrangement of the connections Circuit / connection of the motor winding. 26 Operating Instructions, 06/12,

29 Installation 4.6 Connecting the motor at the terminal box Terminal box NOTICE Please observe the tightening torques for cable glands and other nuts and bolts. When performing a test run, secure the featherkeys without output elements. NOTICE Do not damage the terminal box or other functional parts inside the terminal box. NOTICE It must be ensured that there are no foreign bodies, dirt or moisture in the terminal box. The terminal box must be sealed so that dust and water cannot enter. Seal the terminal box with the original seal. Seal cable entries to the terminal box and other open cable entries with an O-ring or suitable flat gasket. Note For a standard terminal board with 6 terminal studs, the terminal box can be turned 4 x 90 degrees on the terminal base of the machine housing.

Mechanical stress and grease lifetime High speeds that exceed the rated speed and the resulting increased vibrations alter the mechanical running smoothness and the bearings are subjected to increased stress. This reduces the service life of the grease and bearings. Optional add-on units Connect the temperature sensor of the monitoring system and the anti-condensation heating according to the appropriate circuit diagram. Only switch on the anti-condensation heating after the motor has been switched off. 36 Operating Instructions, 06/12,

39 Commissioning Checking the insulation resistance Work on power installations must only be carried out by specialists. WARNING Secure the drive unit to prevent it from being started up unintentionally. Attach a warning notice to the start switch. WARNING All covers which are designed to prevent active / live or rotating parts from being touched, or which are necessary to ensure correct cooling, must be installed prior to commissioning. WARNING During the measurement, and immediately afterwards, hazardous voltage levels are present at some of the terminals and they should not be touched. Carry out a check on the power cables connected to ensure that no voltage can be applied. NOTICE The insulation resistance needs to be checked prior to commissioning and again after any extended periods of storage or periods during which the equipment is not in operation. Before measuring the insulation resistance, read the manual for the insulation resistance meter you are going to use. Disconnect any main circuit cables already connected from the terminals before measuring the insulation resistance. Operating Instructions, 06/12,

40 Commissioning 5.1 Checking the insulation resistance NOTICE If the critical insulation resistance is less than or equal to this value, the windings must be dried or, if the fan is removed, cleaned thoroughly and dried. Note that the insulation resistance of dried, clean windings is lower than that of warm windings. The insulation resistance can only be properly assessed after conversion to the reference temperature of +25 C. If the measured value is close to the critical value, you must subsequently check the insulation resistance at appropriately frequent intervals. Wherever possible, measure the minimum insulation resistance of the winding to the motor housing at a winding temperature of +20 C to +30 C. Other values for the insulation resistance apply for temperatures outside this range. When making the measurement, wait until the final resistance value is reached, approx. 1 minute. Measure the critical insulation resistance at the operating temperature of the winding. Limit values The following limit values are valid for the insulation resistance at a rated voltage of UN < 2 kv and a winding temperature of +25 C. 500 V Measuring circuit voltage 10 MΩ Minimum insulation resistance for new, cleaned or repaired windings 0.5 MΩ / kv Critical specific insulation resistance after a long operating time Observe the following: When measuring at winding temperatures other than +25 C, the measured value must be converted to the reference temperature of +25 C. The insulation resistance is halved for every 10 K increase in temperature, and it is doubled for every 10 K decrease in temperature. If the insulation resistance is close to or below the minimum value, the cause could be humidity and dirt accumulation. The windings must then be dried. During operation, the insulation resistance of the windings can fall to the critical insulation resistance due to ambient and operational influences. The critical insulation resistance for a +25 C winding temperature can be calculated, depending on the rated voltage, by multiplying the rated voltage (kv) by the specific critical resistance value (0.5 MΩ / kv); e.g. critical resistance for rated voltage (UN) 690 V: 690 V x 0.5 MΩ / kv = MΩ. 38 Operating Instructions, 06/12,

We recommend you unscrew and remove the manual brake release lever during operation. Operating Instructions, 06/12,

48 Service and maintenance 8.2 Description of maintenance and repair work The lockable manual release of the brake must be kept in the released state for maintenance work. Figure 8-1 Lockable manual release Locking the manual brake release lever 1. Screw on the manual brake release lever. 2. Bring the manual brake release lever into the position in which the brake is released. 3. Tighten the locking screw far enough so that the manual brake release lever cannot return to the unreleased position. You can now start maintenance work on the system with the brake released. Releasing the lock 1. Unscrew the locking screw far enough so that the brake can completely return to the unreleased position. The gap between the locking screw and the manual brake release lever must be 2 to 5 mm. 2. Unscrew the manual brake release lever. You have ensured that the manual brake release is no longer locked Lubrication The bearings of the standard version surface-cooled motors (up to size 160) are permanently lubricated. If this is not the case, this is indicated by a warning notice on the motor. The specified grease service life values are valid for an ambient temperature of max. +40 C. For every 10 C increase in temperature, the grease service life is reduced by a factor of 0.7 of the value in the table (max. +20 C = factor 0.5). At an ambient temperature of +25 C, the grease service life can be expected to be doubled. Irrespective of the number of operating hours, renew the roller bearing grease or the bearing (2Z bearing) after 3 or 4 years at the latest. 46 Operating Instructions, 06/12,

52 Service and maintenance 8.2 Description of maintenance and repair work Servicing the brake Wear of the spring-operated brake The friction lining and the mechanical components of the brake are subject to wear due to their inherent function. For safe and fault-free operation, the brake must be checked regularly, adjusted and, if necessary, replaced. The following table describes the different causes of wear and their effects on the springoperated brake components. To be able to calculate the service life of the rotor and the brake and to determine the stipulated maintenance intervals, important influencing factors must be quantified. Here, the most important factors are the work as a result of the frictional force, the speed at the start of braking and the switching frequency. Should several of the causes of wear to the friction lining listed occur at the same time in a single application, the influencing factors should be added together for the wear calculation. Table 8-4 Causes of wear to the spring-operated brake Component Cause Effect Influencing factor Friction lining Operational braking Emergency stops Wear caused by overlap when starting up and stopping the geared motor Active braking by the motor supported by the brake (quick stop) Low speed and type of construction 'motor at top' Wear when starting for motor a mounting position with vertical shaft, even when the brake is released Friction lining wear Work as a result of the frictional force Number of start / stop cycles 50 Operating Instructions, 06/12,

53 Service and maintenance 8.2 Description of maintenance and repair work Component Cause Effect Influencing factor Armature disk and flange Friction of the brake lining Braking rotor gear teeth Relative movement and impacts between rotor and hub Support of the armature disk Springs Load change and impacts in the backlash between the armature disk, sleeve screws and guide pins Axial load cycle and shear stresses in the springs due to radial backlash in the armature disk Run-in of armature disk and flange Wear of the teeth (primarily on the rotor side) Deflection of armature disk, sleeve screws and pins Decrease in the spring force or fatigue failure Work as a result of the frictional force Number of start / stop cycles Number of start / stop cycles, strength of braking torque Number of switching operations of the brake Maintenance intervals for the brake For safe and fault-free operation, the spring-operated brake must be regularly checked and maintained. For operational braking, the necessary maintenance intervals are primarily a result of the load on the brake in the application. When calculating the maintenance interval, all the causes of wear must be taken into account. For brakes with a low load, e.g. holding brakes with emergency stop, a regular inspection at fixed time intervals is recommended. A lack of brake maintenance can lead to operating faults, production outage or damage to the plant or system. For this reason, a maintenance plan must be stipulated for each application, appropriate to the operating conditions and load on the brake. The following table lists the stipulated maintenance intervals and maintenance work to be carried out for the pneumatic brake. Table 8-5 Maintenance interval for the brake Brake Operational brake Holding brake with emergency stop Maintenance interval According to service life calculation Otherwise every six months After operating hours at the latest Minimum every 2 years After 1 million cycles at the latest Shorter intervals for frequent emergency stops Operating Instructions, 06/12,

54 Service and maintenance 8.2 Description of maintenance and repair work Adjusting the air gap WARNING Switch off the power supply to the drive unit. The brake must be in a torque-free condition.
