The following rules must be strictly observed:
1. Disconnect electric power: Disconnect power at all connections of the entire installation on which
work is to be carried out.
Warning - hazardous electrical voltage!
Beware of possible external power supplies! BEFORE and AFTER connection it must be checked
that the controller is off load ! All device connections/plugs are only to be plugged in, unplugged and/
or wired when off load.
2. Secure against reconnection of power: Tag the disconnected equipment with the following information:
‐ What has been disconnected from power
‐ Why it has been disconnected
‐ Name of person who disconnected power
‐ Use a suitable lock-out (e.g. padlock) to prevent reconnection of power.
3. Make sure that power is off (authorized and duly trained personnel only):
‐ Check with voltmeter immediately before use.

‐ Check that power is off on all connections at the place of work.
4. Ground and short circuit: Ground and then short circuit all electrical parts at the place of work.
5. Cover or bar off adjacent power-carrying parts: Any equipment carrying power adjacent to the work area
must be covered by suitable means (e.g. insulating cloths or panels).
