WARNING
Risk of explosion or spread of fire from built-in devices
Short circuits in the converter or its components may cause explosion or fire in the control
cabinet, which can result in serious personal injury or property damage.
● Install built-in devices in a suitable and robust metal cabinet in such a way that personnel
are protected against the explosive shock and fire, or take other appropriate protection
measures, for example, using five safety cabinet locks additionally.
Protection against the spread of fire
The device may be operated only 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 contamination
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 may be permitted.
