Installation of Cold Plate
The dissipation of the frequency inverter power loss can take place via coolers that work
with different cooling media (air, water, oil, etc.).
A good thermal connection to the cooler is important for safe operation of the frequency
inverters:
• The contact area between cooler and frequency inverter has to be the size of the
frequency inverter cooling plate.
• Level contact surface, deviation max. up to 0.05 mm.
• Connect cooler and cooling plate with all necessary screw connections.
• The mounting plate must not exceed 70 °C during operation. This limit must be
ensured by the cooling medium.
• Cold Plate installation is not possible with FHS or FKB.

UL compliant installation
Please note the following points for UL compliant installation:
• Use only copper cables with the temperature range 60/75 °C as connection lead:
• Necessary tightening torques of MOVITRAC
®
B power terminals: See installation
notes.
• Operation of inverters on supply systems with a maximum phase-to-earth voltage of
AC 300 V only.
• The inverter can only be operated on IT systems if the phase-to-earth voltage of
AC 300 V cannot be exceeded either during operation or in case of an error.
• The MOVITRAC
®
B frequency inverter is only allowed to be operated on supply
systems which can supply maximum values in accordance with the following table.
Only use melting fuses. The performance data of the fuses must not exceed the
values in the following table.
