Do not disassemble, repair, or modify the EB3 safety relay barrier, otherwise the safety characteristics may be impaired. 2. Use the EB3 within its specification values. 3. The EB3 can be mounted in any direction. 4. Mount the EB3 on a 35-mm-wide DI rail or directly on a panel surface using screws. When mounting on a DI rail, push in the clamp and use end clips to secure the EB3. When mounting on a panel surface, tighten the screws firmly. 5. Excessive noise may cause malfunction or damage to the EB3. When the internal voltage limiting circuit (thyristor) has shut down the power due to noise, remove the cause of the noise before powering up again. 6. The internal power circuit contains an electronic fuse to suppress overcurrents. When the electronic fuse has tripped, shut down the power, remove the cause of the overcurrent before powering up again. 7. Use crimping terminals with insulation sheath for wiring. Tighten the terminal screws, including unused terminal screws, to a recommended tightening torque of 0.6 to m using a screwdriver of ø5.5 mm in diameter. 8. Before inspecting or replacing the EB3, turn off the power. 1. Operate the safety input device to check the EB3 functionality everyday. 2. For safety input devices, such as safety switches or emergency stop switches, connected to the EB3, use safety standard-compliant devices with direct opening action and 2C contacts. 3. Do not use the auxiliary input as a safety input. 4. For safety control devices connected with the EB3, use machine safety standard-compliant devices with a disparity detection function. 5. Use safety inputs and safety outputs in a circuit configuration compliant with safety requirements. 6. To calculate the safety distance, take into consideration the response time of all devices comprising the system, such as the EB3 and safety devices connected to the EB3. 7. Separate the input and output wiring from power lines and motor lines. 8. When using multiple EB3 safety relay barriers, do not connect one switch to more than one EB3. Use separate switches for each EB3. 9. To ensure EMC, use shielded cables for safety inputs and auxiliary inputs. Connect the shield to the FG of the control panel on which the EB3 is mounted. 10. For protection against overcurrents, connect an IEC compliant 2A fast-blow fuse (5 20 mm). 11. Evaluate the ISO category and performance level in consideration of the entire system

13 EB3 otes for Explosion Protection Safety 1. Install the EB3 in an enclosure capable of protecting against mechanical shocks at a hazardous location in accordance with intrinsic safety ratings and parameters. 2. Install and wire the EB3 so that the EB3 is not subject to electromagnetic and electrostatic induction and does not contact with other circuits. For example, keep a minimum spacing of 50 mm between intrinsically safe and non-intrinsically safe circuits, or provide a metallic separating board between the intrinsically safe circuit and non-intrinsically safe circuit. When providing a metallic separating board, make sure that the board fits closely to the enclosure (top, bottom, and both sides). Allowable clearance between the board and the enclosure is 1.5 mm at the maximum. When a motor circuit or high-voltage circuit is installed nearby, keep a wider spacing than 50 mm between intrinsically safe and non-intrinsically safe circuits. 3. Keep a minimum spacing of 3 mm between the terminal or relay terminal block of the intrinsically safe circuit and the grounded metal parts of the metal enclosure. 4. Connect the terminals so that IP20 is ensured. 5. To prevent disengaged wires from contacting with other intrinsically safe circuits, bind together the end of wires. 6. Make sure that the voltage of the power supply for the devices connected to the non-intrinsically safe circuit or the internal voltage of such devices does not exceed 250V AC/DC 50/60 Hz (U rating: 125V AC 50/60 Hz) or 250V DC (U rating: 200V DC) under any normal and abnormal conditions. 7. Make sure that the wiring of intrinsically safe circuits does not contact with other circuits or is not subject to electromagnetic and electrostatic inductions, otherwise explosion protection is not ensured. 8. When identifying intrinsically safe circuits by color, use light blue terminal blocks and cables. 9. When wiring the intrinsically safe circuit, determine the distance to satisfy the wiring parameters shown below. a) Wiring capacitance Cw Co Ci Co: Intrinsically safe circuit allowable capacitance Ci: Internal capacitance of switches b) Wiring inductance w o i o: Intrinsically safe circuit allowable inductance i: Internal inductance of switches c) Wiring resistance Rw Rw: Allowable wiring resistance Switches in the Hazardous Area 1. A switch contains the switch contact, enclosure, and internal wiring. A switch contact refers to an ordinary switching device which consists of contacts only. 2. When the switch has internal wiring or lead wire, make sure that the values of internal capacitance (Ci) and inductance (i) are within the certified values. 3. Enclose the bare live part of the switch contact in an enclosure of IP20 or higher protection. 4. Depending on the explosion-protection specifications of TIIS, the exposed area of plastic switch operator, when installed in Japan, is limited as follows: Certification Explosion Protection Exposed Area T5758 Exia II CT6 20 cm 2 maximum T5961 Exia II BT6 100 cm 2 maximum PCs IDEC (4332) USA & Canada 233

The EB3 can be installed in any direction. 2. Install the EB3 lamp barrier in a safe area (non-hazard ous area) in accordance with intrinsic safety ratings and parameters. To avoid mechanical shocks, install the EB3 in an enclosure which suppresses shocks. 3. When installing or wiring the EB3, prevent electromag netic and electrostatic inductions in the intrinsically safe circuit. Also prevent the intrinsically safe circuits from contacting with another intrinsically safe circuit and any other circuits. Maintain at least 50 mm clearance, or provide a metallic separating board between the intrinsically safe circuit and non-intrinsically safety circuit. When providing a metallic separating board, make sure that the board fits closely to the enclosure (top, bottom, and both sides). Allowable clearance between the enclosure and board is 1.5 mm at the maximum. The clearance of 50 mm between the intrinsically safe circuit and non-intrinsically safe circuit may not be suffi cient when a motor circuit or high-voltage circuit is installed nearby. In this case, provide a wider clearance between the circuits referring to 6. (3) Minimum Parallel Distance between the Intrinsically Safe Circuit and Other Circuits. Precautions for Operation 4. In order to prevent contact between intrinsically safe cir cuits and non-intrinsically safe circuits, mount EB3 units with terminals arranged in the same direction. on-intrinsically Safe Circuit EB3 EB3 EB3 Intrinsically Safe Circuit EB3 EB3 Intrinsically Safe Circuit 5. Maintain at least 6 mm (or 3 mm according to IEC : 1999) clearance between the terminal of intrinsically safe circuit and the grounded metal part of a metal enclosure, and between the relay terminal block of an intrinsically safe circuit and the grounded metal part of a metal enclosure. 6. For installing the EB3, mount on a 35-mm-wide DI rail or directly on a panel using screws. The EB3 can be installed in any direction. Make sure to install securely to withstand vibration. When mounting on a DI rail, push in the clamp completely. Use the B6 end clips on both sides of the EB3 to prevent from moving sideways. 7. Excessive extraneous noise may cause malfunction and damage to the EB3. When extraneous noise activates the voltage limiting circuit (thyristor), remove the noise source and restore the power
