Working on products which have not
been disconnected from the power
supply can cause injury to persons.
Assembly, maintenance, and repair
work may only be carried out by
qualified experts on a product that is not
connected to a power supply. The
supply voltage must be turned off
before any product components are
opened.
The hot surfaces of a motor can cause
burns. The surfaces of motors should
only be touched by persons wearing
appropriate protective gloves or once
the motor has been stopped for a long
period time.
Conveying systems are under pressure
when they are being operated. They
must therefore be depressurized before
assembly, maintenance or repair works
begin and before any changes to the
system are made.
