Loads backed up by the inverter will need to be rerouted from the main electrical
panel to a sub-panel. This can be done several different ways, depending upon the
installation. Always refer to electrical codes for safe wiring practices.

Install a DC disconnect breaker or fuse in the positive (+) battery line. This
breaker protects the DC wiring in the event of an accidental short. Size the
breakers/fuses in accordance with the size of the battery cables in accordance with
your local electrical codes. Switch this breaker/disconnect OFF whenever
servicing the batteries.

The Trace Series can support either 12-volt or 24-volt battery banks, depending on
the model. The battery voltage MUST match the voltage requirements of the
inverter. To determine the correct voltage for the system see the table in “Model
Numbering” on page iv.

Locate the batteries in an accessible location. Two feet (61 cm) clearance above
the batteries is recommended for access to the battery caps. They should be
located as close to the inverter as possible without limiting access to the inverter’s
disconnects. Install the batteries to the left of a wall mounted inverter for easy
access to the DC side of the inverter and shorter cable runs.
For safety and to limit access to the batteries, a lockable, ventilated, battery
enclosure or dedicated room should be used. If an enclosure is used, it should be
vented to the outside by a 1 in. (25.4 mm) vent pipe located at the top of the
enclosure. Install an intake vent at the bottom of the enclosure to promote air
circulation. These vents exhaust explosive hydrogen gases and must not be
overlooked when designing an enclosure.
The enclosure should be made of an acid resistant material or have a finish that
resists acid to prevent corrosion. It should be capable of holding the electrolyte
from at least one battery should a leak occur.
Place a layer of baking soda on the shelves to neutralize any acid that may be
spilled in the future (lead-acid batteries only).
Enclosures located outside must be rainproof and screened to prevent access by
rodents or insects.
