DC Wiring
Safety Instructions
The inverter’s maximum peak current requirements are high. If battery cables are
too small and/or connections are loose, efficiency and maximum output power are
degraded. Small cables or loose connections can also cause dangerous
overheating of the wire and/or terminals.
Make the battery cables as large and as short as possible. Tape the battery cables
together. This reduces the inductance of the wire, resulting in a better waveform
and reduced stress on the inverter’s filter capacitors.
Refer to Table 2-2 on page 2–12 for recommended battery cable size. Crimped
and sealed copper ring terminal lugs with a 5/16" hole should be used to connect
the battery cables to the DC terminals of the inverter/charger. Soldered cable lugs
are also acceptable.
Code your battery cables with colored tape or heat-shrink tubing.
No DC disconnects are provided as an integral part of this inverter. DC
disconnects must be provided as part of the system installation.
Battery Requirements
Type Lead-acid deep-cycle battery or group of batteries. The batteries may be a
flooded, gel, or AGM type.
Volts 12 volts

For detailed information about specific brands of batteries, you will need to
consult individual battery manufacturers.
DC Over-Current Protection
DC fusing In order to comply with the U.S. NEC, an approved form of battery over-current
protection is required. These installation parts are not supplied with the unit.
Standard-type DC fuses or circuit breakers may be obtained from your dealer,
electrical supply houses.
Xantrex offers a DC rated fuse and holder designed specifically for the RV Series
inverters. This fuse holder is available in a 200, 300, 350 and 400-amp sizes (refer
to Table 2-2 for proper fuse size). See the latest Xantrex RV Catalog or visit
www.xantrex.com for more information.
CAUTION: Equipment damage
THIS INVERTER IS NOT REVERSE POLARITY PROTECTED. If the positive
terminal of the battery is connected to the negative terminal of the inverter the probable
result is failure of the whole power stage. This type of failure is not covered under
warranty.
