CAUTION:
1. The Control Circuit Terminal wiring should be kept as far as possible from the main circuit wiring to prevent
operation error due to noise interference. Never install them in the same duct or conduit. A separation distance
of 4 inches or more is recommended. If the control circuit wiring must cross the main circuit wiring, make sure
it crosses at a right angle.
2. Use shielded wire for the control circuit wiring, which should be as short as possible (66 feet or less). Connect
shield to the Drive ground terminal and leave the other end open but taped.
3. Install a surge protector in parallel with any magnetic contactors, solenoids, relays or timer coils which are close
to the Drive.
