Installation and Wiring
Mounting Considerations
Operating Conditions and Temperatures
PowerFlex DC drives are designed to operate at 0
°
to 50
°
C 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
) 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
°
from vertical. In addition, inlet air
temperature must not exceed the product specification.
