Don’t Push It.
Although your WHISTLER inverter has the capacity to pro-
vide power output (excess current) equal to approximately
two times its rated wattage capacity for a very brief period,
it is designed to operate equipment and appliances with
start up load wattage ratings no higher than its own maxi-
mum continuous wattage rating.
For example, the 400 watt model has a maximum continu-
ous rating of 400 watts. Although this model has the capac-
ity to briefly provide up to 800 watts of power (that is, excess
current), it is designed to operate equipment and appli-
ances with start up load requirements of 400 watts or less.
Consequently, if the start up load rating of your equipment
or appliance is the same or approximately the same as the
maximum continuous rating of the inverter, the inverter will
attempt to start loads above the continuous rating for up to
10 seconds.
The inverter is designed to shut down automatically in the
event of a power overload. Testing appliances and equip-
ment with start up load ratings comparable to your inverter
wattage rating will not damage it. However, make sure the
appliance you are testing is compatible with modified sine
wave inverters. See page 4 for more information.

If a piece of equipment or an appliance will not operate, first
confirm that the inverter has been properly connected to
the 12 volt power source (See "Making The Connection"). If
all connections have been properly made, turn the inverter
rocker switch ON (l), OFF (O) and ON (l) again in quick suc-
cession. If this procedure is unsuccessful, it is likely that the
inverter does not have the required start up capacity to
operate the equipment or appliance in question.
Note:
• Most heat generating appliances require start up loads
in excess of 1000 watts and this inverter will not operate
such appliances as coffee makers, irons, hair dryers or
heaters.
