interface drawing provides a visual reference of the terminal board positions with the detailed descriptions
as follows:

This operator is used to shut off the panel output in case of Emergency.
To restart the panel, Reset the E-stop by turn to release.
This white light on the panel door indicates that the circuit breaker/disconnect
switch is closed and that AC power is present at the panel input terminals.
Absence of light from this indicator when it should be "ON" may indicate the
presence of a blown fuse(s) on the primary or secondary of the control power
transformer or a blown bulb.
This green light on the panel door indicates that the drive1 output contactor is
energized and the drive1 may output power to the motor. The conditions that
will cause this light to become energized are – Drive1-Off-Drive2 is in the
"Drive1". Note that this light only means that the drive1 output contactor is
energized and the panel is operating in "Drive1" mode. If the motor's shaft is
not rotating then it may be due to 1) no run command provided to the drive1
(i.e. H-O-A switch in the "Off" position) 2) No Speed ref. 3) an open load side
disconnect

This blue light on the panel door indicates that the Drive2 contactor is
energized. In order for this to happen the Drive1-Off- Drive2 selector must be
in the "Drive2" position and the H-O-A switch must be in either the "Hand" or
"Auto" positions (if "Auto" then remote run contacts must also be closed).
This amber light on the panel door indicates that the Drive-1 is reporting a
fault condition.
This amber light on the panel door indicates that the Drive-2 is reporting a
fault condition.
WARNING: When the disconnect handle is turned to the "On"
position, terminal board points can be at 115 VAC with respect to
ground. Therefore, prior to making any connections to these points lock
the disconnect handle in the "Off" position. In fact, good safety practice
dictates that prior to servicing any electrical equipment that all sources
of electrical energy be disconnected and "locked out" to avoid
reconnection by a third party unaware of the maintenance efforts
underway.
NOTE: Terminal CTB1-1 through CTB1-3 will be at 115V.
