Electric shock
During operation and maintenance, high voltage is at times applied to the device. Because of this,
the device must be de-energised during installation. Persons coming into contact with electrical
lines carrying excessively high voltage can suffer severe electric shocks and, consequently,
injuries.
Only connect electrical circuits to suitable terminals.
3.7.3

As a result of unsuitable operating conditions or careless contact the device or individual
components may be damaged so significantly that the device does not operate correctly or fails
completely.

maximum ambient temperature is never exceeded.
