Installing the XPower Plus
3–21
.
11. Connect the cable from the negative post of the battery to the negative
DC terminal of the inverter.
12. Install the lock washer and nut that are supplied. Tighten the nut to a
torque of 6.3–6.6 foot pounds (8.5–9.0 Nm). Make the connection snug
enough so the ring terminal does not move around on the DC terminal,
but do not overtighten.
This the last cable connection. If you do not have a battery selector
switch that is between the inverter and batteries, and that is in the Off
position, a spark is normal when you make the connection. The
connection sequence in Step 12 ensures that the spark happens away
from the batteries, reducing the risk of fire or explosion.
13. 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).
14. Move the inverter’s On/Off switch to the On position.
The Power light should come on, indicating that the XPower Plus is
ready for operation.
15. Check the
INPUT VOLTAGE DISPLAY. It should read between 12 and
13 volts, depending on the condition of the battery. If it does not, check
your battery and the connection to the inverter, and the state of charge of
the battery.
WARNING: Explosion or Fire
Do not complete the next step if flammable fumes are present.
Explosion or fire may result. Thoroughly ventilate the battery
compartment before making this connection.
