The Utility Tie Breaker contact input must be wired so it is closed when the utility
tie breaker is closed.
The Configurable Alarm or Shutdown Inputs must be wired so they are closed
when the alarm or shutdown condition is true.

Do NOT apply external power to the Discrete Inputs. The application
of an external voltage to terminal 65 will result in permanent damage
to the control.

Relay Outputs
Twelve (Form C type) Relay Outputs are used by the EGCP-2 control to interface
with system devices. Before installation verify that the EGCP-2’s relay contacts
meet the power requirements of the circuit with which it is being interfaced.
Interposing relays are required in cases where the interfaced circuit demands
relay contacts with a higher power rating. If interposing relays are required, it is
recommended that interposing relays with surge (inductive kick-back) protection
be used. The following is a list of the available EGCP-2 Relay Outputs:
