Wiring
1. CONNECTING THE INVERTER AC INPUT (FIGURE 1)
The Inverter AC Input leads (designated “Input Leads”) serve as your normal power sense and charging input for the
internal battery, therefore the
EAC ISSM 375 SM
requires an unswitched AC input of either 120 or 277 VAC. If a local
switch is present on the designated emergency circuit, the
EAC ISSM 375 SM
input must be wired ahead of the switch.
A. For 120V supply, connect the AC line wire to the BLACK lead coming from the inverter housing labeled INPUT
WIRES.
For 277V supply, connect the AC line wire to the ORANGE lead coming from the inverter housing
labeled INPUT WIRES.
CAUTION: Cap the unused BLACK or ORANGE input wire. Failure to do
so may result in equipment failure and void the warranty.
B. Connect the Neutral wire to the WHITE lead labeled INPUT.
C. Connect the ground wire in accordance with local and national codes. A GREEN wire is provided for this purpose.
DO NOT ENERGIZE THE CIRCUIT AT THIS TIME.
2. CONNECTING THE NORMAL AC INPUT (FIGURE 1)
The Normal AC input leads (designated “Flying Leads”) provide normal power to the designated emergency circuit. If
the designated circuit is for Normally-Off fixtures (ie. emergency operation only - come on only during power failure), the
Normal AC input leads are not required and should be capped separately.
A. NORMALLY-ON FIXTURES - Select the proper voltage “flying lead” (BLACK for 120V, ORANGE for 277V)
and connect to the unswitched AC input. Cap the unused lead. Connect the Neutral (WHITE) “flying lead” to the
unswitched AC input neutral of the supply line feeding the input wires. Refer to
Figure 1.
B. FIXTURES ON LOCAL SWITCH (fixtures may be turned on and off locally, but will come on during power
failure regardless of switch position) - Connect the load side of the switch to the proper voltage “flying lead” from
(BLACK for 120V, ORANGE for 277V). Cap the unused lead. Ensure the the Inverter AC Input (“Input Leads” are
connected ahead of the local switch. Refer to
Figure 1.
INSTALLATION INSTRUCTIONS
CAUTION: Before installing, make certain the A.C. power is off.
NOTE: The battery is shipped in separate packaging for ease of handling. Store the battery in a cool, dry and safe
location until ready for installation. The battery may be kept in storage for up to 3 months without recharging.
CAUTION: This is a dual input and output voltage unit. It can be connected to either a 120 or 277 volt supply.
The input and output voltages must match.
NOT FOR USE WITH HID LIGHTING
Mounting the
EAC ISSM 375 SM
1) Remove the front cover of the
EAC ISSM 375 SM
by removing the two (2) screws located at the top of cover.
2) Knock out the keyhole slots at the rear of the unit and use for mounting the
EAC ISSM 375 SM
securely to the wall. There
is an additional round hole for a #10 screw in the cabinet. Code requires that an additional screw be used through this
hole to prevent the unit from being inadvertently lifted up off the keyhole slots.
Do not drill any holes in this unit. If a
recessed junction box is to be mounted in the wall behind the unit, make sure an unswitched AC supply of proper rated
voltage is extended to the box, and that the remote wiring to the emergency fixtures is also extended to the box prior to
mounting the unit. A 1/2
″
conduit knockout is provided in the back of the unit for wires to pass through. Sixteen inches of
wire should be routed into the unit from the recessed junction box. NOTE: Input and output wires must be run in separate
conduits.
CAUTION: Do not drill holes into the cabinet; drill filings may damage the unit and keep it from operating. If larger
knockouts are required, use a chassis-punch through the appropriate knockout to punch out a larger knockout.
3) If the wiring is to be external to the wall, extend both the unswitched supply, the normally-on lamp supply (if used),
and the load wires to the unit at this time.
CAUTION: The
EAC ISSM 375 SM
must be mounted securely. Do not rely on the junction box for supporting the
weight of the unit. Mount the
EAC ISSM 375 SM
securely to the wall using the keyhole slots provided.
ALWAYS CONSULT LOCAL CODES FOR STRUCTURAL REQUIREMENTS WHEN MOUNTING THE UNIT.
