•Work on electrical equipment is only to be carried out by qualified personnel
the regulations currently in force.
•Attention must be paid to the requirements of VDE 0100 when installing high-power
electrical units with nominal voltages of up to 1000V as well as to the associated stand-
ards and stipulations.
•For use in hazardous areas, the relevant national and international standards and reg-
ulations must be heeded.
•When connecting the equipment, attention must be paid to the correct supply volt-
age according to the indications on the type plate.
•Protection against touching dangerously high electrical voltages:
Before opening the equipment, it must be switched off and hold no voltages. This also
applies to any external control circuits that are connected.
•The equipment is only to be used within the permitted range of temperatures.
•Check that the location is weather-protected. It should not be subject to either direct
rain or moisture.
•A residual current protective device (RCD) with a rated value of the fault current of not
more than 100 mA must be used.
•The heating radiator must be covered by a metal protection cover.
•Installation, maintenance, control and eventual repairs may only be done by author-
ized personnel with respect to the relevant stipulations.
•For installation in zone 21:
To prevent electrostatic discharge due to operational processes, for example by con-
