EMIU 400W - 4 Option Mini Inverter
The Mini Inverter model with -4 option can be configured for various modes of operation as described below.
a.
Normally-On Operation
(Refer to Figure 6 for wiring details) - Fixtures remain illuminated in normal AC and emergency modes.
b.
Normally-Off Operation
(Refer to Figure 7 for wiring details) - Fixtures illuminated only upon loss of utility AC power.
c.
Switched Load Operation
(Refer to Figure 8 for wiring details) - Fixtures can be externally controlled and will illuminate upon
loss of utility AC power regardless of the state of the external control device (switch, motion sensor, dimmer, etc.).
d.
Combination of Normally-On, Normally-Off and Switched Load Operation
(Refer to Figure 9 for wiring details - Each circuit in
the Mini Inverter with the -4 option can be configured in one of the previously described modes of operation.
Refer to the applicable wiring diagram in figures 6, 7, 8 and 9 to connect the utility AC power and external control devices (where
applicable). Perform all wiring procedures in accordance with applicable codes. The unit is shipped configured to operate in Normally-On
mode by using an assembled jumper. This jumper can be removed to configure the SWITCHED INPUTS as desired.
Do not connect the load to the Mini Inverter at this point of time.
a. Position the batteries in the unit.
b. Refer to figure 4. 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
.
STEP 4: WIRING TO SWITCHED INPUT
CAUTION:
POWER SUPPLIED TO THE SWITCHED INPUTS MUST BE FED FROM THE SAME BRANCH CIRCUIT AS
THE UNSWITCHED INPUT.
CAUTION:
ALL FOUR SWITCHED INPUTS HAVE BEEN JUMPERED AND IS PRESET FOR 120VAC TO OPERATE
NORMALLY ON LOADS. IF THE UNIT IS TO BE WIRED FOR 277VAC, REMOVE THE JUMPER WIRE FROM
THE 120VAC INPUT POWER TERMINAL AND REINSTALL THE JUMPER WIRE INTO THE 277VAC INPUT
POWER TERMINAL.
CAUTION:
IF CONNECTED TO 277V SWITCHED INPUT, USE A 277V RATED SWITCH. FAILURE TO USE THE PROPER
VOLTAGE SWITCH MAY RESULT IN SWITCH FAILURE, A SHOCK HAZARD, AN UNSAFE
CONDITION AND/OR EQUIPMENT FAILURE.
STEP 5: CONNECT BATTERIES (SEE FIGURE 4)
