Rules for admissible mounting:
• Only mount the Power Module in a vertical position with the motor connectors at the bottom.
• Maintain the minimum clearances to other components.

• Comply with the specified torques.
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.
