Mount the Drive Operating Conditions and Temperatures
PowerFlex DC drives are designed to operate at 0…50 °C (32…122 °F)
surrounding air temperature without derating. The drive 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 are intended to be from drive to drive. Other
objects can occupy this space; however, reduced airflow can cause protection
circuits to fault the drive. The drive must be mounted in a vertical orientation as
shown in
Figure 1 and must not be mounted at an angle greater than 30° from
vertical. Intake air temperature must not exceed the product specification.
