4.1 Safety provisions and instructions for assemblyThe switchgear panels may only be installed and assembled by the manufacturer’s staff or by persons who have been certified for this work.

Warning!Comply with the safety provisions in Chapter 1.

Warning!Risk of accidents in the switchgear compartment!Pay attention to flooring ducts!Warning!Danger due to insufficient dielectric strength of high voltage connections in case of assembly under aggravated ambient conditions. During assembly of the busbar link and the high-voltage connections, it is essential to avoid condensation, dirt and dust deposits.On installation, the ambient temperature must be ≥ 10 °C.The GHA switchgear panels are delivered with the circuit breaker set to “OFF”, the energy storing device released and the isolating and earthing switch set to “OFF”.

Warning!Danger of injury within the vicinity of the drive due to movable parts! The energy storing device of the circuit-breaker must not be tensioned with the operator interface cover removed (see Chapter 4.4).

Important: ■ Switchgear panels with pressure relief duct (see Chapter 7.2):

The pressure relief duct must be installed before positioning the panel on the base frame.

■ For all screw connections which are not defined directly in the assembly description, the tightening torques mentioned in the Annex must be used.

■ Before starting assembly, comply with the design drawings included with the shipment.

4.2 Requirements regarding the switchgear roomBefore installing the switchgear panels, make sure that the switchgear room is checked according to the switchgear documentation (Fig. 4.1):

■ Check floor openings for high-voltage and low-voltage cables. ■ Check position of base frame. ■ The load-bearing capacity of the fastening areas must correspond to the

weight of the switchgear (perform a stress analysis of the building). ■ Observe the minimum clearance between the switchgear and the wall of

the building (Fig. 4.2–4.4). ■ Check base frame for dimensions and positional tolerances.

Before the switchgear is positioned at its site of installation, check that the fastening points are level. The unevenness must not exceed ±1 mm/meter and 2 mm difference in height over the entire switchgear.
