4 SYSTEM START-UP AND TESTING PROCEDURES
WARNING: THESE PROCEDURES ARE TO BE PERFORMED ONLY BY A QUALIFIED
INSTALLER.
After the IQ series inverter has been properly mounted with sufficient ventilation, DC cables have been
connected, AC wiring has been completed, and all remote connections have been checked, the Start-up and
Testing procedure may now be performed.
4.1 Inverter Start-up and Testing
1. Place the System On/Off switch on the inverter and remote LED panel in the OFF position.
2. Remove the front cover of the inverter to access the Programming Switch.
3. Place the Load Demand switch on the internal Programming Switch 2 to the ON position to test Load
Demand function. It can be changed later if this feature is not used.
4. Verify that the external GFCI breaker, breakers, or receptacles are reset and connect an AC load, such
as a 100-Watt light.
5. FOR IQC MODELS - Place the Wet/Gel Setup switch to the correct position for the installed battery type
and place the Equalizer Setup switch to the OFF position.
6. Connect both battery cables to battery and turn on the battery DC power to the inverter (if battery switch
is used).
7. FOR IQC MODELS - Do not connect shore/utility (generator) power at this time.
8. Place the System On/Off switch on the Inverter panel to the START position.
9. Place the System On/Off switch on the Remote panel (if used) to the ON position.
10. Plug AC output test light (eg. 100 watt trouble light) into 15A convenience receptacle and turn on to verify
inverter produces AC power and the Load Demand function powers up from stand-by mode. Applying any
AC load greater than 5 Watts should start inverter from Load Demand “stand by” mode.
11. FOR IQC MODELS - Connect and activate AC shore/power (or generator).
12. FOR IQC MODELS – When shore/utility power (or generator) has been connected the inverter the
following should occur:
If AC test light is off.
Inverter LED will blink slowly
Charge Bulk or Charge Float mode LEDs will illuminate. (If the battery is fully charged, it will
advance from Bulk mode to Float mode after a time delay).
If AC test light is on.
