Recommended Inverter and Battery Care
The CSW3012-X inverter is designed to provide you with years of trouble-free
service. Even though there are no user-serviceable parts, it is recommended
that every 6 months you perform the following maintenance steps to ensure
optimum performance and extend the life of your batteries.
WARNING: Prior to performing these checks, switch both the AC
and DC circuits OFF.
•
Visually inspect batteries for cracks, leaks, or swelling – replace if
necessary.
•
When possible, recharge your batteries when they are about 50%
discharged or earlier. This gives them a much longer life cycle than
recharging when they are almost completely discharged.
•
Use baking soda to clean and remove any electrolyte spills or buildups.
•
Check and tighten all battery hold down clamps.
•
Clean and tighten all DC terminals (battery and inverter) and connecting
cables.
•
If used, check and ensure the screws on the AC input terminals are tight.
•
Check and fi ll battery water levels (Liquid Lead Acid batteries only).
•
Check individual battery voltages (replace those that vary more than 0.3
VDC of each other).
•
Check all cable runs for signs of chafi ng – replace if necessary.
•
Check the inverter's cooling vents – clean as necessary to prevent the
accumulation of dust and dirt.
RV/Marine Off -Season Storage
When placing your coach or boat into seasonal storage, it is recommended
that you perform the following to ensure the system is properly shut down
(or properly confi gured for seasonal storage). This is especially important for
maintaining the batteries.
•
Perform the recommended maintenance steps noted above.
•
Fully charge the batteries; if available, connect a battery charger to
maintain the batteries.
•
Verify the inverter is switched OFF.
•
Switch OFF all unnecessary AC and DC loads.
Testing the GFCI Outlet
Use the steps below to periodically test the GFCI outlet to ensure it is
operating properly.
1.
Turn the inverter on.
2.
Plug a small AC load (e.g., 40W light bulb) into the GFCI's outlet.
3.
Check that the AC load is on (i.e., the bulb lights).
4.
Press the GFCI's TEST button. The GFCI's RESET button should pop out,
and the power should shut off (light bulb goes out).
Note: If the bulb remains lit or the RESET button does not pop out, the
GFCI may not be functioning properly.
5.
Press the RESET button. The AC load should come back on (bulb lights
again).
