WARNING!
Risk of injury due to improper troubleshooting!
Improper troubleshooting can result in serious injuries or even death.
For this reason:
– In case of faults, switch off the control unit, disconnect it from the mains
and secure against restarting. Contact customer service.
– Repair work must be carried out only by qualified personnel, unless oth-
erwise specified.
– Before starting work make sure there is sufficient space for the installa-
tion.
– Pay attention to order and cleanliness at the place of installation. Loose
components and tools lying around or on top of each other are safety
hazards.
– If parts are to be replaced: Ensure correct installation of spare parts. In-
stall all fastening elements properly again. Only use original spare parts.
– Ensure that all covers are properly installed before restarting.
WARNING!
If there is a short-circuit in a 230V/400V load, the contact of a relay can
fuse due to the high short-circuit current. This can lead to steady state of
the consumer. Switch off the automatic circuit breaker in the junction box.
Contact customer service.
