STEP 7: START-UP PROCEDURE
a. Turn on switch located on right hand side of inverter module in the electronic cabinet. Emergency lights and indicator will not
illuminate.
b. Energize AC main supply. Status Indicator on the left side of electronic cabinet will illuminate. For information on the Status
Indicator, see Information Section: FEATURES AND OPTIONS.
c. If status LED Indicator is not green, reset the system. (Refer to "SYSTEM RESET" - page 7).
d. Manually test unit by pressing test switch for 1 second. (Refer to "MANUAL TEST" - page 7).
Note: this will initiate a 1 minute manual test.
e. Measure and record voltage at the output terminal block.
f. Confirm measured output voltage matches voltage rating of the loads.
g. Following the 1 minute test, simulate a power outage by turning off the AC main circuit breaker feeding the Mini Inverter.
h. Measure and record voltage at the output terminal block.
i.
Confirm measured output voltage matches voltage rating of the loads. If voltages do not match, check the wiring or call Technical
Support.
STEP 8: SHUT DOWN PROCEDURE.
a. Turn off switch located on right-hand side of inverter module in the electronic cabinet.
b. Turn off AC main circuit breaker in the service panel feeding the Mini Inverter.
STEP 9: CONNECT THE LOAD.
a. Confirm all circuits are de-energized.
b. Confirm that measured output voltage of Mini Inverter matches voltage rating of loads. Wire load.
c. Identify output terminal block (refer to figures 5, 6 and 7).
d. Connect Ground wires from loads to Ground Bus Bar.
e. Connect neutral wire from load to neutral terminal of output terminal block.
f. The neutral of emergency fixtures must be wired to output terminal block.
g. Do not connect the neutral wire of emergency fixtures to neutral wire of normal non-emergency lighting fixtures.
h. Connect hot wire from emergency lighting loads to the "HOT" terminal of OUTPUT terminal block.
STEP 10: START-UP WITH LOAD CONNECTED.
a. With loads connected, follow the start-up procedure in Step 7.
b. A Normally-ON fixture must be ON, Normally-OFF must be OFF. A Switched Emergency Fixture must only be ON when switch is
in ON position.
c. Re-install the cover of the Mini Inverter using original hardware.
NO WIRING IS REQUIRED FOR THE NEXUS
See Nexus® addendums: 750.1532 and 750.1641 for more information and antenna installation.
See Nexus®Pro addendums: 750.1641 and 750.2060 for antenna installation and important information before powering up unit.
Press test switch for 1 second to initiate a 1 minute manual test. Status Indicator will flash green. All normally-ON lamps (switched or
unswitched) will turn ON. All normally-OFF lamps shall also be ON. After 1 minute test, lamps will revert to normal operating mode and
unit will revert to recharge mode. Status indicator will be steady ON green if no fault has been detected. If a fault is detected, refer to the
FEATURES AND OPTIONS pp. 9-10 for diagnostics and auto test features.
Allow the batteries to charge for a minimum of 48 hours after installation or power failure before conducting a 90-minute discharge test.
The Life Safety Code and the Authorities having Jurisdiction require an annual 90-minute discharge test.
