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 18 .)
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 screen so that the
screen can be twisted into a pig-tail. Keep the pig-
tail short 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.
Note: For R5 frame size, the minimum power cable
size is 25 mm
2
(4 AWG).
For R6 frame size, refer to section Power terminal
considerations – R6 frame size on page 269 .
7. Connect the pig-tail created from the motor cable screen 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
screen into a pig-tail.
11. Route control cable(s) through clamp(s) and tighten
clamp(s).
12. Connect the ground screen pig-tail for digital and
analog I/O cables at X1-1. (Ground only at drive
end.)
13. Connect the ground screen pig-tail for RS485 cables
at X1-28 or X1-32. (Ground only at drive end.)
14. Strip and connect the individual control wires to the
drive terminals. See section Control terminals table
on page 22 .
15. Install the conduit/gland box cover (1 screw).
