300/600W Mini Inverter
INSTALLATION
a. Remove the front cover of the Mini Inverter by removing the two screws at the top of the cover.
b. Extend the unswitched, properly-rated voltage AC supply and remote fixture wires to the installation area.
c. Use keyhole slots at the rear of the unit and mount the Mini Inverter securely to the wall.
d. Connect the conduit containing the AC supply and remote fixture leads to the Mini Inverter. Use the provided knock-outs on the
side of the Mini Inverter for connecting the incoming wires.
e. Install the batteries at this time, but do not connect the battery leads until other wiring is completed.
a. For 120V supply, connect the AC Line wire to the 120V (UN-SWT) position of the INPUT POWER section of the terminal block.
For 277V or 347V supply, connect the AC Line wire to the 277V or 347V (UN-SWT) position of the INPUT POWER section of the
terminal block.
b. Connect the NEUTRAL wire to the NEUTRAL position of the INPUT POWER section of the terminal block.
c. Connect the ground wire in accordance with local and national codes.
d. For Nexus wired (option): Refer to the “WIRING FOR NEXUS
®
” on the page 4.
a. Connect the remote emergency fixtures to the correct position of the LOAD terminal block, respecting the operating voltage. All
remote circuitry is to be wired in accordance with Article 700 of the National Electric Code.
Do not exceed the total rating of the
Mini Inverter. Unit is rated at maximum Watt and maximum VA, where Max.W = Max.VA. Total load (W) must be derated
when load power factor (PF) is less than 0.9 (for maximum rating).
Special attention shall be taken when load consists of LED
lamps with no built-in power factor correction. Example: most of the single LED lamps (Screw-on, GU-10, etc.) have a power
factor of less than 0.6. This translates to a derating close to 50%.
b.
NORMALLY-OFF FIXTURES (only come on during power failure)
- Connect the AC Line input wire of the fixtures to the
appropriate position of the LOAD terminal block (120V OR 277V OR 347V). Connect the fixture Neutral to the Neutral position of
the LOAD terminal block. Refer to Figure 2B.
c.
UN-SWITCHED NORMALLY-ON FIXTURES
- Connect the AC Line input wire of the fixtures to the appropriate position of the
LOAD terminal block (120V OR 277V OR 347V). Connect the fixture Neutral to the Neutral position of the LOAD terminal block.
Refer to Figure 2C.
d.
SWITCHED NORMALLY-ON LOAD
(fixtures may be turned on and off locally, but will come on during power failure regardless of
switch position) - Follow Step 3B above. Connect the Line side of the switch to the (UN-SWT) position of the INPUT POWER
terminal block, respecting the operating voltage (120V OR 277V OR 347V). Connect the load side of the switch to the (SWT)
position on the INPUT POWER terminal block, respecting the operating voltage (120V OR 277V OR 347V). Refer to Figure 2A.
e. Connect the Fixture Supply Ground to the Mini Inverter Ground.
a. Position the battery(s) in the unit.
b. Refer to figures 1A or 1B. Connect the RED wire to the positive (+) post of the battery. Connect the BLUE wire to the negative (-)
post of the battery. Tighten all bolts to a recommended torque of
78 lbf-in ± 4 lbf-in
.
NOTE: THE EMERGENCY LIGHT AND INDICATORS WILL NOT TURN ON AT THIS TIME.
a. Energize the AC supply. The Status Indicator will illuminate. Refer to the operation information below for more information about
the Status Indicator.
b. Normally-ON fixtures shall be ON, Normally-OFF shall be OFF. Switched Emergency Fixtures shall be ON only when the switch is
in the ON position.
c. Manually test the unit by pressing the test switch for 1 second and then release it. (Refer to “MANUAL TEST” for more details).
d. If status LED is not green, reset the system. (Refer to “SYSTEM RESET”).
e. Properly re-install the cover of the Mini Inverter using all the original hardware.
STEP 1: MOUNTING THE MINI INVERTER TO THE WALL
STEP 2: CONNECT THE NORMAL AC INPUT (SEE FIGURE 2A, 2B, 2C OR 2D)
STEP 3: CONNECT THE REMOTE EMERGENCY FIXTURES (SEE FIGURE 2A, 2B, 2C OR 2D)
STEP 4: CONNECT THE BATTERY(S)
STEP 5: SWITCH ON THE INVERTER MODULE (SWITCH IS LOCATED ON THE RIGHT SIDE OF
THE INVERTER MODULE).
STEP 6: COMPLETE THE INSTALLATION
