© 2010 Magnum Energy, Inc.2.0 Installation25Ground-Fault Circuit Interruption (GFCI) BreakersIf installing this inverter in the wiring system of a mobile application(RV, boat, or truck), a Ground Fault Circuit Interrupter (GFCI) mustbe installed to protect all branch circuits powered by this inverter. Incompliance with UL standards, Magnum Energy tested the followingGFCIs and found that they function properly when connected to theinverter’s AC output.Shock SentryTM #XGF15V-SPLeviton Smart Lock #8899-AHubbel #GF520EMBKAWARNING: Risk of electric shock. Use only the GF-CIs [receptacles or circuit breaker(s)] specified in thismanual. Other types may fail to operate properly whenconnected to this inverter.Functional TestAfter all electrical connections to the inverter, batteries, AC source,and loads (using a sub-panel) have been completed, follow thesesteps to test the installation and the inverter’s operation.1. Check the battery voltage and polarity before connecting the bat-teries to the inverter. Use a multimeter to verify 10 to 14 VDC at thebatteries’ positive and negative terminals.2. Apply battery power to the inverter by switching the DC disconnectON (or close the DC circuit-breaker). The inverter will remain OFF,but the green status indicator on the front of the inverter will quicklyblink once to indicate that DC power has been connected and is readyto be turned on.3. Prior to turning on the inverter, make sure all connected loads (e.g.,appliances) are switched OFF or disconnected from the AC outlets.4. a. If a remote switch is connected, press the ON/OFF switch toturn the inverter on.b. If there is not a remote switch connected, lightly press andrelease the inverter’s ON/OFF power switch — located on the top ofthe inverter — to turn the inverter on.Verify the inverter’s status indicator is blinking – indicating the in-verter is providing AC power.5. Check the output voltage of the inverter by connecting a true RMSmultimeter to the outlets powered by the inverter. Verify the voltageis 120 VAC +/- 5 VAC. If not using a true RMS meter the output ACvoltage could indicate from 90 to 130 VAC, depending on the bat-tery voltage.
