Installation Guidelines

Ventilation: Due to the 922 W power loss, ensure adequate cabinet ventilation or cooling to prevent overheating, especially when operating near the 50 degC ambient limit.
Cabling: Use shielded cables for motor connections to minimize electromagnetic interference (EMI). Ensure terminals are tightened to accommodate up to 35 mm2 (2 AWG) wire size.
Grounding: Proper earthing of the drive frame is essential for safety and to comply with electromagnetic compatibility (EMC) standards.
Clearance: Maintain the recommended clearance distances around the drive as specified in the manual to ensure optimal airflow through the heat sink.

FAQ

What is the typical power output of the FC111P37KT4 drive?

The typical shaft output is 37.0 kW or 40.0 hp.

How does the ambient temperature affect the output current?

The drive provides full rated current at 40 degC. At 50 degC ambient temperature, the output current is derated (e.g., to 58.4 A for the 380–440 V range) to ensure reliable operation.

What is the IP rating for this HVAC drive?

This model is rated IP20, suitable for mounting within an electrical cabinet.

What is the maximum cable size compatible with this unit?

The mains and motor terminals accept a maximum cable size of 35 mm2 (2 AWG).
