General Operation
The TruePower400PS Inverter is a sine wave inverter which converts 12 volt directcurrent (DC) power from your batteries to 120 volts alternating current (AC) power. This
AC power is the same quality as the electricity you get from your utility. The TruePower400 PS
Inverter comes equipped with numerous protection features to guarantee safe and
worry-free operation.
GENERAL OVERVIEW
The TruePower400PS provides 400 watts of clean sine wave AC power for your sensitive
entertainment electronics.
Offering superior quality sine wave output, the TruePower400PS sine wave inverter is
designed to power entertainment systems in boats and recreational vehicles. Its clean
utility-grade output does not produce noise and distortion on televisions, LCD and Plasma
TV’s, VCR’s, DVD’s and stereo’s. The TruePower400 PS supplies up to 400 watts of
continuous power and with a surge rating of 1000 watts, it can power complete
entertainment systems including two 27” televisions, or it could also power small appliances,

PROTECTION FEATURES
Low Voltage Shutdown protects the battery from becoming completely discharged by
shutting down automatically if the input voltage drops below 10.5 volts. The TruePower400PS
recovers automatically when the input voltage comes up to 12.4.
High Voltage Shutdown protects the TruePower400 PS by disabling the AC output when the
input voltage rises to 15.6 volts or more. The AC output is enabled when the input voltage drops
to 15.5 volts. Over-temperature Shutdown disables the AC output of the TruePower400 PS
when the internal temperature rises or overloading occurs. The TruePower400PS recovers
automatically after it cools down.
Overload Protection disables the AC output of the TruePower400PS if the appliance
connected to the inverter exceeds the 400 watt rating of the inverter. The TruePower 400PS
will then automatically reset after the overload has been removed.
Short Circuit Protection disables the AC output of the TruePower400PS when a short
circuit is applied on the last AC output. Once the short circuit is cleared, the TruePower400PS
will automatically be reset.
(GFCI) Ground Fault Circuit Interrupter trips and disables the output of the TruePower400PS
when a ground fault current is detected. The output can be enabled again by resetting
the GFCI, once the ground fault is cleared. (GFCI is available in the 79400 model only)

OPERATION CONTINUED
Resetting the Inverter: To reset the TruePower 400PS, turn the ON/Off switch to Off and
then back to ON.
Resetting the Supplemental Circuit Protection Button: If there is a short circuit or an
overload condition, the supplemental circuit protection button trips. To reset the TruePower 400PS,
clear the overload condition then press the supplemental circuit protection button.
Resetting the Ground Fault Circuit Interrupter (GFCI): Function- The GFCI receptacle
protects the receptacle output against a ground fault.
Correcting a Ground When a ground fault condition is detected, the Reset button on the
GFCI receptacle Fault- will trip and the power to an appliance is interrupted. To resume
normal operation, determine and correct the ground fault, then press the Reset button.
Monthly Testing - Once a month, with either shorepower or the TruePower 400PS turned
ON, press the Test button on the GFCI receptacle. The Reset button should trip. Press
it to reset the GFCI and to continue with normal operation. If the Reset button does not
trip, the GFCI may have failed. Contact your dealer or ProMariner to have a qualified
technician inspect the unit.
Resetting as the Result of an Overload:
The TruePower400PS has a high surge capacity of 1000 watts for 5 seconds.
If the appliance(s) connected to the unit try to draw excess power for more than
5 seconds, the TruePower400PS will shut down and the Red Fault light will illuminate.
After removing the overload condition, the TruePower400PS will cycle through a
15 second self check and automatically reset to operating levels.
Operating Several Appliances at the Same Time:
If you are going to operate several appliances from the TruePower400PS at the
same time, turn them on independently, after you have powered up the inverter.
This action ensures that the TruePower400PS does not have to deliver the starting
current for all of the appliances at once. The TruePower400PS can accommodate
several appliances at once as long as they do not exceed more than a combined
total of 400 watts.
Recharging Your Batteries:
We recommend you recharge your batteries before they are 50% discharged. This
will provide a much longer life cycle than recharging them when they are almost
completely discharged. It is recommended to use a Remote Battery Status indicator
to monitor the battery levels and determine optimum recharge times and cycles.
