3.2 Power losses and air cooling requirements

Danger to life due to voltage
To ensure safe operation of the equipment, it must be installed and commissioned by
qualified personnel in full compliance with the warnings laid down in this manual.
It is especially important to comply with general and local installation and safety regulations
for working on plants and systems with hazardous voltages (e.g. EN 61800-5-1) - as well as
the relevant regulations regarding the correct use of tools and personal protective
equipment (PPE).
Protection against the spread of fire
The device may only be operated in closed housings or in control cabinets with protective
covers that are closed, and when all of the protective devices are used. The installation of
the device in a metal control cabinet or the protection with another equivalent measure must
prevent the spread of fire and emissions outside the control cabinet.
Protection against condensation or electrically conductive pollution
Protect the device, e.g. by installing it in a control cabinet with degree of protection IP54
according to IEC 60529 or NEMA 12. Further measures may be necessary for particularly
critical operating conditions.
If condensation or conductive pollution can be excluded at the installation site, a lower
degree of control cabinet protection is permitted.
3.2 Power losses and air cooling requirements
General requirement
Installation in the cabinet and the cooling must guarantee that the air temperature - under all
operating conditions and all possible cabinet equipment configurations - inside the Power
Module at the top in the area of the rectifier modules is a maximum of 65 °C - and the air
intake below the Control Unit (behind the left hand housing flap) is a maximum of 60 °C.
