R e c o m m e n d e d W i r i n g P r a c t i c e s
The following wiring/cabling is recommended for use with the IM483:
M o t o r P o w e r
Belden Part# 9740 or equivalent 18 AWG (shielded twisted pair).
M o t o r
The motor cabling recommended for use will depend upon the distance
in which the motor will be located from the drive.
< 5 feet ................. Belden Part# 9402 or equivalent 20 AWG
> 5 feet ................. Belden Part# 9368 or equivalent 18 AWG
L o g i c W i r i n g
Wire Size ......................................................... 20-22 AWG
G e n e r a l P r a c t i c e s
The following wire strip length and tightening torque is recommended:
Wire Strip Length ........................................ 0.238” (6.0 mm)
Terminal Screw Tightening Torque ......... 4.5 lb-in (0.5 N-m)
WARNING! Do not exceed the recommended tightening torque
for the screw terminals!
WARNING! Do not connect or disconnect any wiring when
power is applied!

Figure 7.1 illustrates the motor power (+V) connection to two IM483
drives using a recommended IMS ISP200-4 unregulated switching power
supply. Shown are the proper wiring practices of using shielded twisted
pair wiring, with the shield tied to AC ground and the driver end left
floating. Each drive is wired to the power supply separately, rather than
daisy-chained together. Following these principles will reduce the elec-
trical noise in your system and help eliminate a major cause of erratic
system perfomance.
Please note that an AC line conditioner is also shown. This protects your
system from potential damage resulting from line spikes and surges.
