2. WIRING
1. CONNECTING THE NORMAL AC INPUT (FIGURE 1)
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.
Note: If the emergency fixtures are to be NORMALLY ON or SWITCHED, you may have to connect their flying
lead wires to these wires as well. Refer to DIagrams 1 and 2 and STEP 2 below.
DO NOT ENERGIZE THE CIRCUIT AT THIS TIME.
2. CONNECTING REMOTE EMERGENCY FIXTURES (DIAGRAMS 1 and 2)
A. Connect remote emergency fixtures to the correct output leads. The color code is as follows: neutral is GRAY,
120V is VIOLET, and 277V is YELLOW. 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
IIS-550-I-DR. When making connections to the
IIS-550-I-DR, DO NOT connect the Input Neutral (WHITE) to the Output Neutral (GRAY).
B. NORMALLY-OFF FIXTURES (only come on during power failure) - Connect the AC line input wire of the fixtures
to the appropriate output wires as above (120V or 277V). Connect the load neutral wire to the GRAY neutral
wire labeled OUTPUT. Refer to
Diagrams 1 and 2.
C. NORMALLY-ON FIXTURES - Follow Step 2B above. Then select the proper voltage flying lead from heatsink
assembly (BLACK for 120V, ORANGE for 277V) and connect to the unswitched AC input wires. Connect the
Neutral (WHITE) flying lead coming from the heatsink assembly to the unswitched AC input neutral of the sup-
ply line feeding the input wires. Refer to
Diagrams 1 and 2.
D. FIXTURES ON LOCAL SWITCH (fixtures may be turned on and off locally, but will come on during power
failure regardless of switch position) - Follow Step 2B above. Connect the line side of the Switch to the
unswitched AC input wires. Connect the load side of the Switch to the proper voltage flying lead from the heat-
sink assembly (BLACK for 120V, ORANGE for 277V). Refer to
Diagrams 1 and 2.
CAUTION: If connected to 277 volt 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 equipment failure.
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.
1. MOUNTING THE IIS-550-I-DR
1) Remove the front cover of the IIS-550-I-DR 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 IIS-550-I-DR 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 un-
switched 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 IIS-550-I-DR must be mounted securely. Do not rely on the junction box for supporting the
weight of the unit. Mount the IIS-550-I-DR securely to the wall using the keyhole slots provided.
ALWAYS CONSULT LOCAL CODES FOR STRUCTURAL REQUIREMENTS WHEN MOUNTING THE UNIT.
