4.6 BATTERY PRECAUTIONS
1. Wear splash-resistant ANSI-approved safety goggles and electrically-insulated gloves
while working near batteries.
2. Charge, store, and maintain batteries according to supplier’s instructions.
3.
Locate batteries in a clean, well-ventilated area, away from ignition sources and flammable
materials. Vented lead-acid batteries release explosive hydrogen gas while charging.
4. Only connect similar batteries together. Do not connect old and new batteries together,
flooded and gel cells together, or batteries of different capacities together.
5.
Only connect this Inverter to a 12V nominal battery bank. Do not attempt to connect
the Inverter to any other power source other than a battery with a nominal output
voltage of 12 volts or damage to the Inverter may occur and will void the warranty.
6. Connect batteries in parallel ONLY (negative terminals together to one cable; positive
terminals together to the other cable).
7.
Install a properly rated fuse on the positive output of the battery bank. See section
4.7 DC WIRING SIZE.
The following points must be observed for the DC Wiring.
•
The DC positive and negative cables connected to the Inverter from the battery
bank should be linked together with zip ties or electrical tape every 6”. This helps
to reduce radio frequency interference and reduces the effects of inductance both
of which improve the Inverter waveform and reduces the wear of the Inverters
filter capacitors.
•
To ensure optimum Inverter performance the number of connections between
the battery bank and the Inverter unit should be minimized except from the
over-current and battery disconnect devices. All additional connection points
will cause extra voltage drops.
•
The Battery bank voltage must match the DC voltage required by the Inverter,
which is 12V.
•
All DC cable wire terminations should use a crimped and sealed copper ring
terminal lugs.
•
Make sure all cables have a smooth bend radius and no kinks are present.
•
Colour code all DC Cables coming to/from the battery bank. Use coloured
electrical tape or heat shrink tubing. Red for positive (+), Black for negative (-)
and Green for DC ground.
