CONTROL CIRCUIT WIRINGCONTROL CIRCUIT WIRING

CONTROL CIRCUIT WIRING

Control circuit wiring connections (low voltage DC

and 120 volt AC) are terminated on terminal strip

4TB4. Shielded cable should be installed for all low

voltage DC control signal wiring. The shield of the

cable must be connected to the negative terminal for

the control signal. Do not connect the shield at the

other end of the cable. Insulate the shield so that no

electrical connection is made at the other end of the

cable.

CONNECTIONS

For automatic speed tracking, the drive is supplied

with an interface circuit for inputs from a system con-

trol panel. The input signal wiring is terminated to

terminals 13(+) and 14(-) of terminal strip 4TB4.

These connections are used for both DC voltage and

current input signals. Selection of the type of follower

to be used is made by the position of the SW2 switch

labeled 4-20mA as shown below.

OUTPUT/MOTOR DISCONNECT

It is recommended that any device which can discon-

nect the motor from the output of the drive be inter-

locked to the emergency shutdown circuits of the

drive. This will provide an orderly shutdown if the dis-

connecting device is opened while the drive is in op-

eration. Interlock contacts should be installed in se-

ries with terminals 5 and 6 of terminal strip 4TB4.

CONDUIT ENTRYCONDUIT ENTRY

CONDUIT ENTRY

All 1703 model drives are designed for conduit entry

at the top of the enclosure. A removable conduit entry

plate is provided for ease of installation.

1. Mark the location of the conduit entries for

input power, motor wiring and control wiring

on the conduit entry plate.

2. Remove the conduit entry plate.

3. Drill the conduit entry holes in the plate.

4. Reinstall the plate on the drive and connect

the conduit to the plate.
