Mounting Considerations 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 (indicated in Figure 1 ) are intended to be from
drive to drive. Other objects can occupy this space; however, reduced airflow may
cause protection circuits to fault the drive. The drive must be mounted in a
vertical orientation as shown below and must not be mounted at an angle greater
than 30 degrees from vertical. In addition, inlet air temperature must not exceed
the product specification.
