Troubleshooting!
At the beginning of troubleshooting, all possible sources of faults on
additional devices or supply lines (measuring lines, wiring, downstream
devices) should be taken into consideration. If the fault was not found
after checking these points, we recommend sending the device to the
supplier.
Decommissioning!
Switch off the power supply on all poles if the device is to be
decommissioned. Secure the device against unintentional operation!
If the device is connected to other devices and / or equipment, the effects
must be considered and appropriate precautions taken before switching
off.
The following special regulations must be observed:
Connect cables professionally in glands.
Close not needed housing bores with locking bolts.
Cleaning of the housing is only permitted with moist cleaning agents to avoid static
charging.
Cleaning is necessary to prevent increased dust generation on the device.
Operation under voltage, in zone 22, only in closed state.
Before closing, ensure that the device housing is free of dust
