8.3.5 Placement Of The Power Force 150™
For best operating results, the inverter should be properly installed (as directed in this manual) in the
INDUSTRIAL 900™. The combined unit should only be used in locations that meet the following criteria:
DRY—Do not allow water or other liquids to come into contact with unit.
COOL—Ambient air temperature should be between -20° C and 40° C—ideally between 15° C and 25° C
(60 - 80° F). Do not place the unit on or near a heating vent or any piece of equipment which is generating heat
above room temperature. Keep the unit away from direct sunlight, if at all possible.
VENTILATED—Keep the area surrounding the
Power Force 150™ 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 temperature exceeds 90° C.
Restart the unit once it cools down sufficiently.
SAFE—Do not use the unit near flammable materials or in any locations that may accumulate flammable fumes
or gases.
8.4 OPERATING TIPS
8.4.1 Rated versus Actual Current Draw of Equipment
Most electrical tools, appliances and audio/video equipment have labels that indicate the power consumption in
amps or watts. Be sure that the power consumption of the item you wish to operate is rated at 200 watts or less.
(If the power consumption is rated in amps, simply multiply by the AC volts (110) to determine the wattage).
Example: AMPS (1) X VOLTS (110) = 110 WATTS
The inverter has overload protection, so it is safe to try to operate equipment rated at 200 watts or less. The
inverter will shut down if is overloaded, and will restart once the overload is rectified.
Resistive loads are the easiest for the
Power Force 150™ to run; however, larger resistive loads, such as electric
stoves or heaters, usually require more wattage than the
Power Force 150™ can deliver on a continuous basis.
Inductive loads, such as TVs and stereos, require more current to operate than do resistive loads of the same
wattage rating. Induction motors, as well as some televisions, may require 2 to 6 times their wattage rating to start
up. The most demanding in this category are those that start under load, such as compressors and pumps. Testing is
the only definitive way to determine whether a specific load can be started and how long it can run. The unit will
simply shut down if it is overloaded. To restart the unit after a shutdown due to overloading, momentarily turn off
the power to the unit.
THIS UNIT WILL NOT OPERATE APPLIANCES AND EQUIPMENT THAT PRODUCE HEAT, SUCH AS
HAIR DRYERS, MICROWAVE OVENS, AND TOASTERS.

8.5 TROUBLESHOOTING
8.5.1 Protective Features of the Power Force 150™
The Power Force 150™ monitors the following potentially hazardous conditions:
Low Battery Voltage - This condition is not harmful to the inverter but could damage the INDUSTRIAL 900™.
An audible alarm will sound when input voltage drops to 10.6. The
Power Force 150™ automatically shuts
down when input voltage drops to 10.0-volts. The
INDUSTRIAL 900™ must be fully recharged. Then the unit
may be restarted.
Over Voltage Protection—The
Power Force 150™ will automatically shut down when the input voltage exceeds
15-volts DC.
Short Circuit Protection—Reverse polarity or a short circuit condition will usually result in the fuse being blown.
Immediately disconnect the shorted load and replace the fuse of the
Power Force 150™ as described in the
VEC023
Power Force 150™ operation manual.
Overload Protection—The inverter will automatically shut down when the continuous draw exceeds 150 watts.
Over Temperature Protection—When the temperature sensor inside the
Power Force 150™ reaches 150° F, the unit
will automatically shut down. Allow the unit to cool for at least 15 minutes before restarting after a heat-related
shutdown. Unplug unit while cooling.
CAUTION: LOW BATTERY ALARM
An alarm will sound when the voltage from the battery drops to 10.6-volts. This is an indication that the battery
needs to be recharged.
STOP OPERATION OF THE ELECTRONIC DEVICE IMMEDIATELY since the Power
Force 150™
will shut down automatically shortly thereafter, when the battery voltage drops to 10-volts. Recharge
the
INDUSTRIAL 900™, per the instructions in this manual.
8.5.2 Common Problems
“Buzzing” sound in audio systems
Some inexpensive stereo systems and “boom boxes” emit a buzzing sound from their speakers when operated from
the
Power Force 150™ power inverter. This occurs because the power supply in the electronic device does not
adequately filter the modified sine wave produced by the
Power Force 150™. The only solution to this problem is
to use a sound system that incorporates a higher quality power supply.
T
elevision Interference
The Power Force 150™ is shielded to minimize interference with TV signals. However, in some instances, some
interference may still be visible, particularly with weak TV signals. Try the following corrective measures:
Position the unit as far as possible from the television, the antennae and the antennae cables. Use an extension
cable, if necessary. Adjust the orientation of the unit, the antennae cables and the TV power cord to minimize
interference. Make sure that the antennae feeding the television provides an adequate (“snow free”) signal and that
high quality, shielded antennae cable is used.
