Prosine 2.5/3.0 Installation & Operation Guide 55
Section 5: Operation
After all the AC and DC wiring has been installed, you can follow the instructions below to perform
the initial startup. First, take a moment to go back over all connections and make sure they are secure
and in the proper terminal. If the system utilizes flooded lead-acid type batteries instead of sealed gel-
cell type, use the ACS or the DIP switch settings to change the set-up for battery type from gel-cell to
flooded lead-acid. If you don’t know which battery type you have, use the gel-cell setting just to be
safe, and then contact the battery manufacturer.
1. Verify that the DIP switch settings are correct for
your system. See “Section 3: Configuration” if
you have the standard control panel, or the ACS
Control Panel section if you have that.
2. Check to see that the inverter BYPASS/ON slide
switch is in the BYPASS position.
3. Connect the battery cable (or close the battery disconnect switch) to complete the
battery circuit. Turn the inverter BYPASS/ON slide switch to the ON position. The
System Startup Default is set at the factory at INV OFF/ CHG ON. Press the Inverter
ON/OFF switch on the control panel to enable the inverter. When the DC connection is
completed, the inverter will begin inverting if there is an AC load and the AC
shorepower has not been connected.
4. Place a load on the inverter (plug in a light or other load to an outlet the inverter is
powering), and make sure it works. The inverter should run a load without AC
shorepower connected (battery only).
5. If the inverter does not come on or go through the start-up, check all connections.
Check the inverter’s DC voltage on the positive (+) and negative (–) terminals. If the
DC voltage is low or if the battery bank needs to be charged, go directly to Step 6.
6. To charge your batteries, connect shorepower to the inverter by plugging in the
shorepower cord and turning on the shorepower breaker. After a few seconds delay, the
utility/shorepower LED should light and the Charge LED on the front of the inverter
should indicate it is charging. This indicates the charger is working properly. Any AC
loads connected to the AC output should also work at this point.
The delay before connecting to the utility AC supply is the inverter sampling the
shorepower to see that it is within acceptable frequency and voltage limits. This delay
also allows time for a generator to spin up to a stable operating condition before the
inverter/charger places a load on it.
7. Disconnect shorepower by turning the shorepower breaker off, or unplugging the
shorepower. The inverter should transfer to inverter mode immediately. This will be
indicated by a clicking sound as the internal transfer relays change position. The loads
should continue to operate uninterrupted.
The preceding steps will complete a functional test of the inverter. If all areas pass, the inverter is
ready for use. If any area fails, determine why before proceeding. “Appendix C: Troubleshooting”
will help you solve problems you encounter.
