Connect the Protective Earth (PE) and Power Cables

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH All wiring must comply with all applicable local and/or national electrical codes. Wiring may only be done by an authorized electrician. Always check the rating plate for details. For AC wiring pay attention to the voltage, frequency and if applicable the phase rotation. For DC wiring pay attention to the polarity. Check that the cables and connections are according to the Drawings. Failure to follow these instructions will result in death or serious injury.

DANGER
HIGH LEAKAGE CURRENT The system must be connected to protective earth. Always connect the system to protective earth before connecting any power supply. Failure to follow these instructions will result in death or serious injury.

Before connecting any power cables to the terminals, all cabinets must be connected to the protective earth. High leakage currents are present when the system is connected to the mains supplies.

The type of terminals depends on the system rating, configuration and customer specifications. There are three standard types:

Push in terminals
Bolt terminals and an earth bolt terminal (connected to the internal earth bar) or an earth bar
Copper bars and an earth bolt terminal (connected to the internal earth bar) or an earth bar
