3. CONNECTING EMERGENCY FIXTURES (FIGURE 1)
A. Connect emergency fixtures to the correct output leads. The color code is as follows: YELLOW/VIOLET for
120/277V and GRAY for NEUTRAL. 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
EAC ISSM 375 SM
.
When making connections to the
EAC
ISSM 375 SM
, DO NOT connect the Input Neutral (WHITE) to the Output Neutral (GRAY).
B Connect the Fixture Supply Ground to the
EAC ISSM 375 SM
Ground.
DO NOT ENERGIZE THE CIRCUIT AT THIS TIME.
Consult the
EAC ISSM 375 SM
Application Notes for connecting the unit to specific lighting loads. Application Notes are
available on the internet or through Customer Service.
4. CONNECTING THE INTERNAL CIRCUIT BREAKER
A. Two leads are provided for connection to the internal circuit breaker. Select the proper voltage lead (VIOLET
for 120VAC or YELLOW for 277VAC) and connect it to the circuit breaker. Cap the unused lead. Push the circuit
breaker switch to the ‘closed’ position so that the indicator on the circuit breaker shows RED.
CAUTION: Before proceeding to Wiring Step 4, make sure that all unused wires are properly capped.
Failure to do so may result in an unsafe condition and equipment failure.
DO NOT ENERGIZE THE CIRCUIT AT THIS TIME.
5. INSTALLING THE BATTERY
ATTENTION:
Use only battery part number
ELB AC04 with the unit. See Page 1 of this instruction manual.
A. Before installing the battery, check the torque on the hardware that connects the polarized connector to the
terminals as these connections may have loosened in transit and storage. The proper torques should be
70 in/lbs for a
Screw Stud terminal, and 65 in/lbs for an L Flag terminal.
B. Install the battery into the
EAC ISSM 375 SM
with the terminal posts facing toward the front of the unit. NOTE:
The
EAC ISSM 375 SM
battery is heavy. To avoid injury, exercise caution when handling the battery.
C. Plug the battery connector together.
Note: Neither the indicator lights nor the emergency fixtures will illuminate at this time. Also, please note that
there are 2 battery tie down lugs in the event that it is required that the battery be held in place. Please contact
Customer Service to purchase this accessory if needed.
For Screw Stud batteries, initial torque is 70 in/lbs, annual is 65 in/lbs.
For L-Flag batteries, initial torque is 65 in/lbs, annual is 52 in/lbs.
NOTE: The emergency indicator lights will not illuminate at this time.
6. COMPLETING INSTALLATION
A. Energize the AC supply. The Ready (Yellow) Indicator and the Charging (Red) Indicator will illuminate.
The Inverter On (Green) Indicator will not illuminate at this time.
