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 dange-
rous to life.
Therefore:
– For switching off the mains, the power supply cable must be
equipped with a fuse with a contact opening width corresponding to
the requirements of the excess voltage category III for total discon-
nection.
– Disconnect the unit from the mains before carrying out any work on
it (switch off the fuse in the distribution box) and secure against re-
starting. Check for zero potential. The control device should be dis-
connected 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 certified electricians
only.
– Never bypass fuses or put them out of operation.
– While replacing fuses, pay attention to correct current specifications.
– Keep moisture away from live components, since it can lead to short
circuit.
WARNING!
If a short circuit occurs in a 230V/400V load, the relay contact can
be welded by the high short-circuit current. Is turned on before
removing the short circuit, the safety relay can be also welded.
This can lead to the continuous operation of the load. Turn off the
circuit breaker in the distribuition box. Send the unit back to the
factory for check/repair.
