Xantrex XPower 3000 Installation Guide
NOTICE
REVERSE POLARITY
DC power connections to the XPower inverter must be
positive to positive and negative to negative. A reverse
polarity connection (positive to negative) will blow a fuse in
the XPower inverter and may permanently damage the
XPower inverter. The fuse is not user replaceable and the
XPower inverter may need to be returned for servicing.
Damage caused by a reverse polarity connection is not
covered by your warranty.
Failure to follow these instructions can result in equipment
damage.
Observe the polarities carefully while completing the
installation. Use a wrench to tighten to a torque of 216–240
inch-pounds (24–27 Nm). Test that the cable is secure.
NOTICE
EQUIPMENT DAMAGE
n
Do not over-tighten the nut on the DC input terminals.
Damage to the DC input terminals may result.
n
Loose connections cause excessive voltage drop and
may cause overheated wires and melted insulation.
Failure to follow these instructions can result in equipment
damage.
6. Connect one connector on the negative cable to the
negative terminal on the DC end. Before proceeding, check
that cable polarity is correct, and then connect the other end
of the cable to the negative (–) terminal on the battery.
This is the last cable connection you make. If the disconnect
switch or breaker is not turned off, a spark is normal when
the connection is made. Use a wrench to tighten to a torque
of 216–240 inch-pounds (24–27 Nm). Test that the cable is
secure.
7. Attach the DC terminal covers.
8. Before proceeding, double check that you have connected
the cables properly—positive to positive, negative to
negative.
9. Turn on the battery disconnect switch or breaker.
10. If you have installed a battery selector switch, use it to
select one of the batteries or battery banks (house bank
preferred over start bank).
11. Turn the XPower inverter’s On/Off switch to the On
position.
12. Test sample loads by plugging appliances into the AC
receptacles and check to see if they work properly.
Alternatively, if a load sub-panel or additional AC outlets are
hardwired into the inverter AC output, test that appliances
plugged into the additional outlets are working properly.
