Plug the line cord into an outlet providing 120V AC, 60 Hz. power. Make sure that the circuit
you connect your APS to has adequate overload protection, such as a circuit breaker or a fuse.
Simply plug your equipment into the unit’s AC receptacles.
• Switch to “AUTO/REMOTE” when you are using connected equipment. ADVANTAGE:
APS will automatically switch from providing connected equipment with utility power to
providing connected equipment with power inverted from external batteries when utility
power is unavailable.
Note: When the switch is in the “AUTO/REMOTE” position, you can operate a user-supplied switch to transfer
between battery-backup and charge-only modes. (See Remote Connector manual for more information.)
• Switch to “CHARGE ONLY” when you are not using connected equipment. (WARNING!
APS will not provide battery backup!) ADVANTAGES: A) Continues to charge battery
when power is present, and B) Turns OFF the APS’s inverter, preventing battery drain
during blackouts or brownouts.
• Switch to “OFF” to completely turn off the APS and connected equipment or to reset the
APS after it has shut down due to overload or overheating.
(See Diagrams 10a and 10b, p. 38-39, to locate the following switches, indicator lights and other
features.)
1. Operating Mode Switch: This switch selects the APS operating mode (either
“AUTO/REMOTE”, “OFF” or “CHARGE ONLY”). See “Set Operating Mode Switch”, p. 11
to select the optimum setting for this switch.
2. “CONFIGURATION SWITCHES”—DIP Switch Group A: These four switches must be
set for the type of battery your APS will be connected to and the voltage points at which your
APS will switch to battery power. See “Configuration”, p. 5 to select the optimum settings for
these switches.
3. “CONFIGURATION SWITCHES”—DIP Switch Group B: These DIP Switches allow
you to equalize the internal resistance of your battery’s cells and set the percentage of your
model's maximum load at which the APS will limit battery charging. See “Configuration”, p.
6 to select the optimum settings for these switches.
