EMIU 400W - 4 Option Mini Inverter

a.   Confirm load is not connected. 
b. Follow start-up procedure in Step 7.

   

    

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 mains supply. Status Indicator on the left side of electronic cabinet will illuminate. For more information about the Status 

Indicator, see information section FEATURES AND OPTIONS.

c. If status LED Indicator is not green, reset the system. (Refer to “SYSTEM RESET” on page 7).
d. Manually test unit by pressing test switch for 1 second. (Refer to “MANUAL TEST” on the page 7).
e. Measure and record voltage at the output of circuits 1, 2, 3 and 4. 
f. Confirm measured output voltages match voltage rating of the loads.
g. Following the 1 minute test, simulate a power outage by turning off the AC mains circuit breaker feeding the Mini Inverter. 
h. Measure and record voltages at the output of circuits 1, 2, 3 and 4. 
i. Confirm measured output voltages match voltage rating of the loads. If voltages do not match, check the wiring or call Technical 

Support. 

a.   Turn off switch located on right-hand side of inverter module. 
b. Turn off AC mains circuit breaker in the service panel feeding the Mini Inverter.      

a.   Before proceeding, confirm all circuits are de-energized.
b. Upon confirmation that measured output voltage of Mini Inverter matches voltage rating of loads, wire load.
c. Identify output terminal block (refer to figures 6, 7, 8 and 9).
d. The neutrals of circuit# 1, circuit# 2, circuit# 3 and circuit# 4 are shorted.
e. Connect Ground wires from loads to Ground Bus Bar.
f. Connect neutral wires from loads to neutral terminals of output terminal block. 
g. The neutrals of emergency fixtures must be wired to output terminal block.
h. Do not connect the neutral wire of emergency fixtures to neutral wire of normal non-emergency lighting. 
i. Connect hot wires from emergency lighting loads to the "HOT" terminals of OUTPUT terminal block.   

a.   With loads connected, follow the start-up procedure in Step 7. 
b. Normally-ON fixtures must be ON, Normally-OFF must be OFF. Switched Emergency Fixtures must only be ON when switch is in ON 

position. 

c. Re-install the cover of the Mini Inverter using original hardware.

STEP 6: START-UP WITH NO LOAD CONNECTED.

STEP 7: START-UP PROCEDURE

STEP 8: SHUT DOWN PROCEDURE.

STEP 9: CONNECT THE LOAD.

STEP 10: START-UP WITH LOAD CONNECTED.
