Work on Live Parts

DANGER

Maintenance and installation work may only be carried out by
authorised persons.

DANGER OF FATAL INJURIES

NEVER assume that a circuit is dead - ALWAYS check it for
safety’s sake! Contact with live parts can cause serious or fatal
burns and inner injuries by electrocution.

Voltage may only be applied to components being worked on when this
is expressly prescribed (e. g. during trouble-shooting or setup).

The mains switch is live even when the controller is switched off.

During work always observe: the relevant regulations for the prevention
of accidents

l

VDE 0105,

l

EN 292.

Only use suitable, intact tools and measuring instruments!
