3.2Monthly Maintenance

•Check the electrolyte level of each Wet-Cell battery cell monthly after the batteries have been charged. The level should be about one-half inch above the top of the plates, but not completely full. Note: This check is not necessary for maintenance- free batteries.

•Check the battery connections for tightness and corrosion. If any corrosion is noted, disconnect the cables and clean them with a mild solution of baking soda and water. DO NOT ALLOW THE SOLUTION TO ENTER THE BATTERY. When finished, rinse the top of the battery with clean water.

•To reduce corrosion on the battery terminals, coat them with a thin layer of petroleum jelly or anti-corrosion grease. Do not apply any material between the terminal and the cable lugs; the connection should be metal to metal. Apply the protective material after the bolts have been tightened.

3.3 Battery Installation

Caution! Batteries can produce extremely high currents. Review both the important safety instructions at the beginning of this manual and the battery supplier’s precautions before installing the inverter and batteries.

3.3.1 Battery Location

Batteries should be installed in an accessible location with good access to the battery caps and terminals. At least two feet of overhead clearance is recommended. Batteries must be located as close as possible to the inverter. Do not install the inverter in the same compartment with non-sealed batteries (sealed batteries are acceptable). The gasses produced by non-sealed batteries during charging are highly corrosive and will shorten the life of the inverter.

3.3.2 Battery Enclosure

Batteries should be installed in a locked enclosure or room. The enclosure should be well ventilated to prevent accumulation of hydrogen gasses that are released during the battery charging process. The enclosure should be made of acid-resistant material or coated with an acid-resistant finish to prevent corrosion from spilled electrolyte and released fumes. If the batteries are located outdoors, the enclosure should be rainproof and have mesh screens to prevent insects and rodents from entering. Before installing the batteries in the enclosure, cover the bottom with a layer of baking soda to neutralize any acid spills.

3.4 Battery Connection

3.4.1 Connect your Inverter/Charger to your batteries using the following procedures:

•Connect DC Wiring: Though your Inverter/Charger is a high-efficiency converter of electricity, its rated output capacity is limited by the length and gauge of the cabling running from the battery to the unit. Use the shortest length and largest diameter cabling to provide maximum performance (see­ table below). Shorter and heavier-gauge cabling reduces DC voltage drop and permits maximum transfer of current. Your Inverter/Charger is capable of delivering peak wattage at up to 200% of its rated continuous wattage output for brief periods of time. Heavier-gauge cabling should be used when continuously operating heavy-draw equipment under these conditions. Tighten your Inverter/Charger and battery terminals to approximately 3.5 Newton-meters of torque to establish an efficient connection and to prevent excessive heating at the connection. Insufficient tightening of the terminals could void your warranty.
