DANGER
Electrical voltage
The supply cable may carry high electrical voltage that is fatal. Pay attention to the five safety rules of
electricity:
1. De-energise.
2. Secure the supply from being switched on again.
3. Ensure the de-energised condition.
4. Connect to earth and short circuit.
5. Cover or cordon off adjacent live parts.
Choose the required cable cross-sections and line fuses based on the specifications given on the
nameplate (see Design and function [} 8]).
