NOTE:
1. The control works only with 1387 drives
that use 115V ac and have the dynamic
braking option. Refer to Bulletin 1387 User
Manual (Publication 1387-5.0) for power
wiring and motor connection.
2. We recommend installation of this connection. Remove it if
excessive noise from chassis ground occurs.
3. The connection from the termination panel to the drive should
be as short as possible. We recommend less than 20 ft.

If your control has terminal 8,
then connect it to chassis ground.
If terminal 8 is not present on
your control, then this type of
grounding is not necessary.
