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 and DC fuse sizes
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 AC Phase 1 to the terminal “1A” and connect the Neutral to “1B”. For a 240Vac input; connect the
AC Phase 1 to the terminal “1A” and connect Phase 2 to “1B”. Before making the DC connections, 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.

The A75R includes customer connections for Remote
Charger Shutdown as well as a single set of form C
contacts for the Charger Fail Alarm. See Section 2.3 for
