2.5 Operationalsafetyandspecialdangers
Pay attention to the safety and warning notes in the following chapters of
this manual to minimize health hazards and to avoid dangerous situations.
The following instructions are to be adhered to for your own safety
and the safety of the unit:
DANGER!
Danger to life due to electric potential!
Contact with live components can be fatal.
Damage of the insulation of the individual components can be dangerous
to life.
Therefore:
– For switching off the mains, the power supply cable must be equipped
with a fuse having a contact opening width corresponding to the require-
ments of the excess voltage category III for total disconnection.
– Disconnect the unit from the mains before carrying out any work on it
(switch off the fuse in the distribution box) and secure against restarting.
Check for zero potential. The control device should be disconnected
from the mains before opening the casing.
– In case of damage to the insulation, switch off the power supply im-
mediately and carry out the repair.
– Work on electrical unit should be carried out by certied electricians
only.
– Never bypass fuses or switch them off.
– While changing the fuses, pay attention to correct current specica-
tions.
– Keep moisture away from live components, since it can lead to short
circuit.
WARNING!
If a short circuit occurs in a 230V/400V appliance, the high short-circuit
current can cause the contact of a relay to fuse. If the unit is switched
on again before the short circuit has been rectied, the safety relay can
also fuse. This will then cause the appliance to run continuously. Switch
off the circuit breaker in the junction box. Return the device to the factory
for testing/repair.
