1. Overview and Features
1.3 Optional Features
1.3.1 Operational Considerations
1. Cold Starting – This unit will cold start only at 60Hz. Do not use this feature if the connected equipment cannot handle a
60Hz frequency.
2. The unit continues to draw from the DC source in OFF mode in order to keep the microprocessor active. The batteries
may be depleted if in the unit is in OFF mode for extended periods of time. The unit will charge the batteries if placed in
STANDBY mode with an active A/C source.
1.3.2 Battery Temperature Port
This port allows connection of a Battery Temperature-Sensing Cable (sold separately). The sensing function prolongs battery
life by adjusting the charge float voltage level based on battery temperature. Connect the sensor cable to the RJ11 port
labeled BATTERY TEMP SENSOR. With user-supplied cyanoacrylate adhesive (“Super Glue”), secure the sensor to the top of
the battery near the negative terminal. Make sure that nothing, not even tape, comes between the sensor and the side of the
battery. If the sensor cable is not used, the Inverter/Charger will charge according to its default 25°C values.
1.3.3 Communication Port (for APSRMSW Remote Control)
This unit allows connection of the APSRMSW Remote Control (sold separately) through the inverter’s ASNET port for
remote monitoring. The remote control allows the Inverter/Charger to be mounted out of sight in a compartment or cabinet
and operated conveniently from a remote location. See the instructions packed with the remote control module for more
information.
2. Battery Charger
2.1 Mode of Operation
The internal battery charger and automatic transfer relay allow the unit to operate as a battery charger, an inverter or a switch.
An external AC power source (e.g. utility power or generator) must be connected to the inverter’s AC input in order to allow
it to operate as a battery charger. When the unit is operating as a charger, AC loads are powered by the external AC power
source.
2.2 Transfer Switching Speed
Transfer time is approximately 20 milliseconds.
3. Battery
3.1 Select Battery Type
Select “Deep Cycle” batteries to receive optimum performance from your Inverter/Charger. Do not use ordinary car or starting
batteries or batteries rated in Cold Cranking Amps (CCA). If the batteries you connect to the Inverter/Charger are not true Deep
Cycle batteries, their operational lifetimes may be significantly shortened. If you are using the same battery bank to power the
Inverter/Charger as well as DC loads, your battery bank will need to be appropriately sized (larger loads will require a battery
bank with a larger amp-hour capacity) or the operational lifetimes of the batteries may be significantly reduced.
Batteries of either Wet-Cell (vented) or Gel-Cell /Absorbed Glass Mat (sealed) construction are ideal. 6-volt “golf cart”, Marine
Deep-Cycle or 8D Deep-Cycle batteries in series-parallel connection are also acceptable. Auxiliary batteries must be identical
to the vehicle batteries if they are connected to each other.
