Installation
Mounting
NEMA 4X cased drives come with three 0.88 inch (22 mm) conduit
knockout holes at the bottom of the case. The units may be vertically wall
mounted using the four 0.25 inch (6 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. Lift or 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) conduit 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
0
(OFF) position before applying the AC
line voltage.
Wiring
Use 14 AWG wire for AC line voltage (L1 and L2) and motor armature
(A1 and A2) wiring. Use 16 AWG wire for motor field (F1 and F2) and
tachogenerator (T1 and T2) wiring.
