WIRING PROCEDURES

REMOVE TERMINAL BLOCK COVER

Remove the terminal block cover as follows
(see Figure 4-1):
1. Remove the screw(s) located at the bottom of the
cover.
2. Press upward on bottom of cover and lift off.
3. See Figure 4-2 for the location of the Main Circuit
Terminal Block and the Control Circuit Terminal Block.
WARNING:
Some printed circuit boards and drive components may
contain hazardous voltage levels. If LED light CRG 1 on the
Base Driver Board is illuminated, hazardous voltages are
present in the drive circuit boards. Remove and lock out
power before you disconnect or reconnect wires, and
before you remove or replace fuses and circuit boards. Do
not attempt to service the drive until the LED indicator has
extinguished and the bus voltage has discharged to zero
volts.

CONTROL CIRCUIT WIRING

drive is wired at shipment for operation and frequency
setting through the keypad panel (frequency is set at 60 Hz.)
– See Figure 4-3 & 4-4 for wiring connections.
– See TABLE 4 for description of all terminals.
Make wire connections as shown in Figure 4-4 through 4-6
for desired mode of external operation through control
circuit terminals.
– See TABLE 4 for description of all terminals.
CAUTION:
The control circuit terminal wiring should be kept as far away
as possible from the main power wiring to prevent opera-
tional error due to noise interference. Never install both
types of wiring in the same duct or conduit. (A separation
distance of 4 inches [10 centimeters] or more is recom-
mended.) If the control circuit wiring must cross the main
power wiring, it should cross at a right angle.
CAUTION:
Use shielded or twisted wire for the control circuit wiring
(wiring should be as short as possible, i.e. 65 feet or less [20
meters].) Connect outer covering of the shielded wires to the
drive ground terminal and leave the other end open, but
taped.
CAUTION:
Install a supressor in parallel with any relays or solemoid
type coils that may be close to the drive to prevent noise
from causing drive misoperation.
