Recommended Inverter and Battery Care
The MM-AE Series inverter/charger is designed to provide you with
years of trouble-free service. Even though there are no user-service-
able 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 the batteries for cracks, leaks, or swelling –
replace if necessary.
•
Use baking soda to clean and remove any electrolyte spills or
buildups.
•
Check and tighten all battery holddown clamps.
•
Clean and tighten (10 to 12 foot-pounds) all DC terminals
(battery and inverter) and connecting cables.
•
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 cha
fi
ng – replace if necessary.
•
Check the inverter’s cooling vents – clean as necessary.
