Whistler WATT PRO-800W - Manual (Page 7)

OPERATION
Making the Connection.
This inverter is designed to connect to your 12 volt battery
by the supplied #8 AWG gauge cables.
1. Make certain that the inverter’s rocker switch is in the
OFF (O) position.
2. Connect the cables to the power input terminals at
the rear of the inverter and tighten the screws to make
a secure connection. Do not use tools to tighten
these screws.
3. Connect the cable from the (BLACK) Negative (-)
terminal on the inverter to the Negative (-) terminal on
the 12 volt power source. Make certain the
connection is secure.
4. Confirm that the cable you have just installed is
properly connected. Specifically, make certain that
the cable is connected to the Negative (-) terminals on
both the inverter and the 12 volt power source.
5. Connect the cable from the (RED) Positive (+) terminal
on the inverter to the Positive (+) terminal on the
power source.

OPERATION

Note:
• Loose connections can result in a severe decrease in
voltage which may cause damage to the wires and
insulation.
• Failure to make proper connection between the
inverter and the power source will result in reverse
polarity. Reverse polarity will blow the internal fuses
in the inverter and may cause permanent damage to
the inverter. Damage caused by reverse polarity is
not covered under the Whistler warranty.
• Making the connection between the Positive (+)
terminals may cause a spark as a result of current
flowing to the capacitors in the inverter. This is a
normal occurrence. Due to the potential for
sparking, however, it is extremely important that both
the inverter and the 12 volt battery be well removed
from any possible source of flammable fumes or
gases.
Failure to heed this warning could result in fire or
explosion.
6. For safe and proper operation of the inverter when
not using the supplied cables, connect the inverter
to the power source with the proper gauge wire
available and in the shortest length practical. When
the inverter and the battery are set up within four feet of
each other, use a minimum of #8 gauge wire to make
the connections. Within four to six feet, use #6 gauge
wire. At distances between six feet to ten feet, use #4
gauge wires connected to the battery.
