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 4-2,4-3
&
4-4 for wiring connectrons.
-
See TABLE 4 for description of all termrnals.
Make wire connections as shown
In
Figure 4-4 through 4-6
for desired mode of external operatron through control
circuit termrnals.
CAUTION:
The control crrcurt termrnal wiring should be
kept as far away as possible from the main power wiring to
prevent operational error due to noise interference
Never
install both types of wiring
In
the same duct or conduit (A
separation distance of 4 inches
[lo
centrmeters] or more
IS
recommended.) 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 possrble, 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 with electrical insulating tape.

CAUTION:
Install a supressor
In
parallel with any relays
or solenord type
coils
as shown above, that may becloseto
the Drive to prevent noise from causing Drive mrsoperatron.
