Mounting (NEMA 12 enclosures)

NEMA 12 cased drives come with two 0.88 inch (22 mm)

conduit knockout holes at the bottom of the case. 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.

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 case. The

right side of the cover is hinged to the case. Pull the slotted

screw to open the case.

3. Carefully remove the conduit knockouts by tapping them into

the case 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 case.

6. Turn the slotted screw clockwise until tight to secure the front

cover.

7. Set the POWER switch to the OFF position before applying the

AC line voltage.
