Installation
Wiring IP21 / UL type 1 enclosure with cables
1. Open the appropriate knockouts in the conduit/gland
box. (See section Conduit/Gland kit on page 19 .)
2. Install the cable clamps for the power/motor cables.
3. On the input power cable, strip the sheathing back far
enough to route individual wires.
4. On the motor cable, strip the sheathing back far
enough to expose the copper wire shield so that the
shield can be twisted into a bundle (pig-tail). Keep the
bundle not longer than five times its width to minimize
noise radiation.
360° grounding under the clamp is recommended for
the motor cable to minimize noise radiation. In this
case, remove the sheathing at the cable clamp.
5. Route both cables through the clamps.
6. Strip and connect the power/motor wires and the
power ground wire to the drive terminals. See the
table on the right for tightening torques.
Note: For R6 frame size, refer to section Power
terminal considerations – R6 frame size on page 277 .
7. Connect the bundle (pig-tail) created from the motor
cable shield to the GND terminal.
8. Install conduit/gland box and tighten the cable clamps.
9. Install the cable clamp(s) for the control cable(s).
(Power/motor cables and clamps not shown in the
figure.)
10. Strip control cable sheathing and twist the copper
shield into a bundle (pig-tail).
11. Route control cable(s) through clamp(s) and tighten
clamp(s).
12. Connect the ground shield bundle (pig-tail) for digital and
analog I/O cables at X1-1. (Ground only at the drive end.)
13. Strip and connect the individual control wires to the
drive terminals. See section Control terminals table
on page 24 . Use a tightening torque of 0.4 N·m
(0.3 lb·ft).
14. Install the conduit/gland box cover (1 screw).
