1. Check to be sure the inverter’s power switch is turned off and that
no flammable fumes are present.
2. Identify the positive (+) and negative (-) DC power source
(battery) terminals.
3. Install a fuse holder or breaker dose to the positive (+) terminal of
the DC source (battery).
4. Connect a length of wire on one side of the fuse holder or circuit
breaker. Connect the other end of the wire to the Positive (+)
terminal of the inverter.
5. Connect a length of wire between the inverter’s negative (-)
terminal and the DC power source negative (-) terminal.
6. Connect a short length of wire to the other terminal of the fuse
holder or circuit breaker. Mark it “POSITIVE” or ‘+’.
7. Connect the free end of the fuse or breaker wire to the positive
terminal of the DC power source (battery).
8. Insert an 150 to 200 Amp fuse in the fuse holder.
9. Test the inverter by turning it on and plugging in a 100 watt lamp
or equipment.
l0.lf the inverter is not properly operating, then refer to the trouble-
shooting sections of this manual.
CAUTION:
Loose connectors may cause overheated wires and melted
insulation. Check to make sure you have not reversed the polarity.
Damage due to reversed polarity is not covered by our warranty.
4.3 CONNECTION TO LOAD
The SI-750HP is equipped with triple standard North American AC power
receptacles. Plug the cord from the equipment you wish to operate into
the AC receptacle. The green LED indicator lights to indicate that the
inverter is functioning. Make sure the combined load requirement of your
equipment does not exceed 750 watts.
The SI-750HP is engineered to be connected directly to standard
electrical and electronic equipment in the manner described above
Do
Not Connect
the Power Inverters to household or RV AC distribution
wiring.
Do not connect the Power Inverter to an AC load circuit in
which the neutral conductor is connected to ground (earth) or to
the negative of the DC battery) source.

WARNING: Do not connect to AC distribution wiring!
CAUTION: RECHARGEABLE APPLIANCES
Certain rechargers for small nickel cadmium batteries
can be damaged by the modified sine wave form of the
input voltage. For example, small battery operated ap-
pliances such as flashlights, razors and night lights
which are directly plugged into the AC outlet or, cer-
tain battery chargers for battery packs used in hand
power tools.
This problem does not occur with the majority of battery-oper-
ated equipment. Most of these devices use a separate charger
or transformer that is plugged into an AC receptacle. The SI-
750HP is easily capable of running most chargers and trans-
formers.
4.4 PLACEMENT OF THE INVERTER
For best operating results, the inverter should be placed on a
flat and/or solid surface. The inverter should only be used in
locations that meet the following criteria:
DRY - Do not allow water and/or other liquids to come into
contact with the SI-750HP inverter.
COOL - Ambient air temperature should be between 30°F (-1
°C) non-condensing, and 105°F (40°C). Do not place the in-
verter on or near a heating vent or any piece of equipment
which is generating heat above room temperature. Keep the
inverter away from direct sunlight, if at all possible.
VENTILATED - Keep the area surrounding the inverter clear to
ensure free air circulation around the unit. Do not place items
on or over the inverter during operation. A fan is helpful if the
inverter is operating at maximum power outputs for extended
periods of time. The unit will shut down if the internal tempera-
ture exceeds 90°C. The unit will restart after it cools.
SAFE - Do not use the inverter near flammable materi-
als or in any locations that may accumulate flammable
fumes or gases.
