Hazardous electrical voltage
Since the voltage is supplied from an external source, voltage may still be present in all of
the cabinets even when the main switches in all units are open.
You must observe the "five safety rules" when carrying out maintenance work.
Note
Temperature-controlled supply voltage
The supply voltage can be provided by means of a temperature control, to prevent the anti-
condensation heating unnecessarily operating at a higher ambient temperature.
