3. When attaching the DC inverter cables to the power input terminals on the rear panel
of the power inverter. The (+) terminal is positive and (-) terminal is negative. Tighten
the terminal bolt or nut to clamp the wires securely. Ensure connections are tight.
4. Connect the ground cable to the appropriate location; see section 4.6 Grounding.
5. Connect the cable from the negative terminal of the inverter to the negative terminal
of the battery. Make a secure connection.
Loose connections result in excessive voltage drop and may cause
overheated wires and melted insulation. Ensure connections are tight.
6. Before proceeding further, carefully check that the cable you have just connected is
going from the negative terminal of inverter to the negative output terminal of the
power source (battery).
7. Install the inverter fuse into the positive lead. Fuse should be located within 12”
(31 cm) of battery. Ensure all connections are tight and secure.
8. Connect the cable from the positive terminal of inverter to the positive terminal of the
battery. Make a secure connection. Check your polarity.
This inverter cannot supply power to any AC distribution wiring or AC
loads in which the neutral and ground are connected (bonded). Doing so
will destroy the unit and void the warranty. If you do not understand
neutral to ground bonding then please have a professional install your
system for you. See “Grounding” for more information.
9. Set the power switch to the ON position. Check the meters and indicators on the front
panel of the inverter. The voltage bar graph should indicate 11 to 14 V depending on
the voltage of the power source. If it is does not, check your battery bank and the
connections to the inverter. The other indicators should be OFF.
10. Set the power inverter switch to the OFF position. The indicator lights may blink and
the internal alarm may sound momentarily. This is normal. Plug the test load into the
AC receptacle on the front panel of the inverter.
11. Set the power inverter switch to the ON position and turn the test load on; the inverter
should supply power to the load. If you plan to measure the output voltage of the
inverter, a true RMS meter must be used for accurate readings.
