Enclosed drive
Mounting
The NEMA 4X enclosed drive comes with 0.88 inch (22
mm) conduit knockout holes at the bottom of the
enclosure. The units may be vertically wall mounted using
the four 0.19 inch (5 mm) slotted holes on the attached heat
sink. For motor loads less than 5 ADC, the drive may be
bench mounted horizontally, or operated without mounting.
Mount the drive as follows:
1. Install the mounting screws.
2. For access to the terminal strip, turn the slotted screw on
the front cover counterclockwise until it is free from the
enclosure. The right side of the cover is hinged to the
enclosure. Pull the slotted screw to open the enclosure.
3. Carefully remove the conduit knockouts by tapping them
into the enclosure and twisting them off with pliers.
4. Install conduit hardware through the 0.88 inch (22 mm)
knockout holes. Connect external wiring to the terminal
block.
5. Grasp the slotted screw and tilt the front cover back into
place. Avoid pinching any wires between the front cover
and the enclosure.
