2. Wiring Customer Interlocks

Wire the Customer Interlock as shown in Figure 2.25. Both the 24V
Regulator Board Terminal Strip and the 115VAC CON2 Terminal
Strip utilize terminal #9 and #11 as the connection point for a
Customer Interlock. All customer interlocks must be closed for
Drive operation and CANNOT be masked.

3. Wiring the Motor Thermostat/Brush Wear Circuits

Either a 24VDC or 115VAC input can be used to receive an external
voltage for a normally closed contact used in a motor thermostat
circuit. As shown in Figure 2.26, Terminal 13 is used for the motor
thermostat circuit on both 24VDC and 115VAC configurations. If
the motor thermostat circuit is open, the Drive will display a fault
and coast to a stop.

Terminal 12 is used for a level sensitive input that triggers a motor
brush wear alarm. The Drive will continue to operate under this
condition. Both the MOTOR BRUSH WEAR and MOTOR
THERMOSTAT inputs are always active and CANNOT be masked.
