wish to operate is rated at 750 watts or less (If the power consumption is rated in amps AC,
simply multiply by the AC volts (120) to determine the wattage). The inverter has overload
protection, so it is safe to try to operate equipment rated at 750 watts or less. The inverter
will shut down if it is overloaded. The overload must be removed before the inverter will
restart. Resistive loads are the easiest for the Vector Power Inverter to run. However, larger
resistive loads, such as electric stoves or heaters, usually require more wattage than the
Vector Power Inverter can deliver on a continuous basis. Inductive loads, such as TV’s 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, remove the overload.
CAUTION: This inverter will not operate high wattage appliances or equipment that
produce heat, such as hair dryers, microwave ovens, and toasters.
5.2 BATTERY OPERATING TIME
With a typical vehicle battery, a minimum operating time of 2 to 3 hours can be expected.
In most instances, 5 to 10 hours of operating time is achievable. However, Vector
recommends that the operator start the vehicle every half hour to recharge the battery
system. This will guard against any unexpected shut-down of the equipment and will ensure
that there is always sufficient battery capacity to start the vehicle’s engine. The inverter will
sound it’s alarm when DC voltage drops to 11.0V.
The inverter may be used whether or not the vehicle’s engine is running. However, the
inverter may not operate while the engine is starting since the battery voltage can drop
substantially during cranking.
The inverter draws less than 1.4 amps from the battery when it is not supplying power to a
load and switch is in ON position. In most instances, the inverter can be left connected to
the battery when not in use since it draws so little current. However, if the vehicle is to
remain unused for several days, disconnect the inverter from the battery.
6. PROTECTIVE FEATURES OF THE INVERTER
Your Vector Power Inverter monitors the following potentially hazardous conditions:
Low Battery Voltage - This condition is not harmful to the inverter but could damage the
power source. An alarm will sound when input voltage drops to 11.0 Volts. The Vector
Power Inverter automatically shuts down when input voltage drops to 10 volts. When the
condition is corrected, the unit may be restarted.
Overvoltage Protection - The Vector Power Inverter will automatically shutdown when the
input voltage exceeds 15.5 volts DC.
Short Circuit Protection - Reverse polarity or short circuit condition may cause external
or internal fuses to open and may cause irreversible damage to the inverter. Take extra care
to insure a proper polarity hook-up.
Overload Protection - The inverter will automatically shut down when the continuous draw
exceeds 750 watts. When the overload is removed, the inverter will self-start.
Over Temperature Protection - If the temperature inside the Vector Power Inverter
reaches 150 degrees 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.
If the low voltage alarm sounds when the battery is fully charged, follow the steps for
