PowerFlex DC Drive and Field Controller Technical Data
Mounting
Maximum Surrounding Air Temperature Specifications
• 0…50 °C (32…122 °F), typical
• De-rate 1.25% for every 1 °C (34 °F) over 50 °C (122 °F), to 55 °C (131 °F)
• Additional cooling is required for temperatures above 55 °C (131 °F)
Operating Conditions
The drive and/or field controller must be mounted in a clean, dry location. Contaminants such as oils, corrosive vapors, and abrasive debris
must be kept out of the enclosure. NEMA/UL Type Open, IP20 enclosures are intended for indoor use primarily to provide a degree of
protection against contact with enclosed equipment. These enclosures offer no protection against airborne contaminants.
Minimum Mounting Clearances
Minimum clearance requirements (shown here) are intended to be from device to device. Other objects can occupy this space; however,
reduced airflow can cause protection circuits to fault the drive. The device must be mounted in a vertical orientation (as shown in the
illustration) and must not be mounted at an angle greater than 30° from vertical. In addition, inlet air temperature must not exceed the
product specification.
IMPORTANT
Verify that all mounting screws are properly tightened before and after operation.
