19 Design and description Overview of rated supply voltages.8 Technical data for electrical control and operating devices The panels have been designed on principle for manual operation. The drive mechanisms of the individual switching devices can be equipped, depending on the specific customer's model, with additional electrical control and operating devices. These are defined in the switchgear-specific circuit diagram (see switchgear documentation). Component fitting options: Motor drive for actuation of the earthing switch Blocking coil The blocking coil prevents manual actuation of the earthing switch. In case of failure of or switching off the supply voltage, all blocking coils are in their "locked" position. Auxiliary switches Auxiliary switches are always actuated directly in front of the truck by the switch shaft via an intermediate linkage. Their position always corresponds to that of the main contacts. The switching functions have been set in the factory according to the circuit diagram. Micro switches are used depending on the customer-specific panel models.

21 3 Packaging, transport, storage 3. Shipping units The conditions and types of transport have been stipulated in the contract details. The type of packaging depends on the type of transport and the storage conditions. The panels are delivered individually and are fastened on pallets. The standard accessories are included. In the case of panels with a width of 800 mm, the trucks can be delivered within the panels. They are in "disconnected" position. With 000 mm wide panels, the trucks are delivered in separate packaging. The panels are delivered in vertical position. The weight of the entire transport unit is indicated on the packaging. Packaging If packed exclusively for truck transport, the panels are delivered on a pallet with PE protective film (Fig. 7). For sea transport, the units are packed in sealed aluminium foil with desiccant and in a closed wooden case with tightly closed wooden base (also for container transport, Fig. 8). In case of air transport, the panels are packed in wooden crates with a protective PE film hood (dust protection) or in wooden crates, also with closed wooden bases, however without protective hoods (dust protection, Fig. 8).

Do not charge the energy storing devices of the circuitbreakers and earthing switches during assembly. WARNING Risk of falling! Watch out for floor openings in the switchgear room. The tops of the panels are not meant to be walked on. When working on top of panels, protect the workplace. The switchgear panels may only be installed and assembled by the manufacturer s staff or by persons who have been certified for this work. 5. Instructions for assembly PIX High panels are delivered with the earthing switch ON. In the case of panels with a width of 800 mm, the trucks can be delivered within the panels. They are in disconnected position. The circuit breakers are always shipped in open state ( OFF ) with the energy storing device released. NOTICE Condensation, dirt and dust should be avoided during assembly on all accounts, in order to prevent damage to the panels. For assembly, observe the assembly drawings supplied with the equipment. Read them before you commence assembly work. The drawing numbers are specified in this manual in the description of the assembly work in question. For all screw connections, refer to the tightening torques specified in the Annex. 5.3 Requirements regarding the switchgear room Before installing the switchgear panels, make sure that the switchgear room is checked according to the switchgear documentation (Fig. 6). Observe the minimum distance between the switchgear and the wall of the building. The load-bearing capacity of the fastening areas must correspond to the weight of the switchgear (perform a stress analysis of the building). Check base frame (if used) for dimensions and positional tolerances. Check position of floor openings for high-voltage and low-voltage cables. Before the switchgear is positioned at its site of installation, check that the fastening points are level. Unevenness must not exceed ± mm/meter and 6 mm difference in height over the entire switchgear width. NOTICE Observe switchgear-specific space assignment plan. 30 AGS Edition /04
