Figure 4: User Installed Auxiliary Relay Card (Frames D, E, & F Only)
Important: If using auxiliary motor control, ensure that wiring and parameter
configuration are correct before wiring contactor outputs. All relays
on the Auxiliary Relay Card will energize on power-up by default.
Failure to verify proper wiring and parameter configuration can result
in improper motor operation or drive damage. Refer to Appendix D
for more details.
