Input/Output Connections
After the A75R is mounted, the input and output connections can be made. The A75R is equipped with ¼” AAR
style hardware for the input/output connections. The wire should be sized based on the AC Draw listed on the
front of the unit and DC Breaker size.
Figure 4 - Input/Output Connections
Using Figure 4 above, Connect the AC input to the terminals shown as “1A” and “1B”. For a 120Vac input;
connect the Neutral to the terminal “1A” and connect the AC Phase 1 to “1B”. For a 240Vac input; connect the
AC Phase 2 to the terminal “1A” and connect Phase 1 to “1B”. Before making the DC connections, make sure
the DC Breaker is off, then verify the DIP switch settings for DC output (Section 2.2). Connect the DC output
(observe proper polarity). DC negative connects to the terminal shown as “1D”. DC positive connects to “1E“.
Connect the ground to the center ground terminal.

Customer Connections
The A75R include customer connections for Remote Charger
Shutdown as well as a shared set of form C contacts for the
Charger Fail and Low Current Alarms. See Section 2.3 for
further information on the operation of the alarm contacts.
The Remote Shutdown and Alarm connections are made via a
spring type connector that accepts 16-22 AWG wire. The
contacts are rated for up to 2A @ 12VDC (1A @ 24VDC).
To install wires, simply depress the spring with a small flathead
screwdriver (about 0.1 inch diameter) in the upper slot and plug
the signal wire into the circular connectors below the slot.
