OPERATION
7. Turn the inverter rocker switch to the OFF (O) position.
(The GREEN LED Power Indicator light may "blink"
briefly and/or the internal audible alarm may make a
momentary "chirp". This is normal).
8. Confirm that the equipment or appliance to be oper-
ated is turned off. Plug the equipment or appliance
into one of the three AC receptacles on the front
panel of the the inverter.
9. Turn the inverter to the ON (I) position. Turn on the
equipment or appliance.
Note:
• As indicated in Step 7 above, the audible alarm may
make a momentary "chirp" when the inverter is
turned OFF (O). The same alarm may also sound
when the inverter is being connected to or discon-
nected from the 12 volt power source. Again, this is
normal.
• The use of an extension cord from the inverter to the
appliance or equipment being operated will not sig-
nificantly decrease the power being generated by the
inverter. For best operating results, the extension
cord should be no more than 50 feet long.
• Check frequently to ensure that the input and output
connections are secure. Loose connections may dam-
age the inverter, the power source, or may generate
excessive heat.

OPERATION
Important Information on Battery Chargers
Using your inverter to re c h a rge units designed to charge such
p o rtable equipment as power tools, flashlights, video cameras
and laptop computers may cause damage to the inverter
or the charging unit. Check with the appliance manufacture r
for compatibility with sine wave inverters if you're unsure .
Although we advise against it, if you attempt to re c h a rge a
c h a rging unit, monitor the temperature of the charging unit
for approximately 10 minutes. If the charging unit becomes
unusually warm, disconnect it from the inverter immediately.
Don't Blow A Fuse.
The PP750AC is equipped with three 35 amp spade type
fuses. With reasonable care, it should not be necessary to
replace the fuse(s) in your invert e r.
Most blown fuses are the result of reverse polarity or a short
c i rcuit within the appliance or equipment being operated. If
the fuse(s) does blow, turn off and disconnect the appliance
or equipment from the inverter immediately, repair the
related problem and replace the fuse(s). The fuse compart-
ments are easily accessed at the back of the unit undern e a t h
the "lift up" covers.
