INSTRUCTION MANUAL

IMPORTANT SAFEGUARDS

When using electrical equipment, basic safety precautions should always be followed, including the following:

READ AND FOLLOW ALL SAFETY INSTRUCTIONS

1. DO NOT USE OUTDOORS.

2. Do not mount near gas or electric heaters.

3. Do not use this equipment for other than its intended use.

4. The IIS-550-I should be mounted securely and in locations and at heights where it will not readily be sub
jected to tampering by unauthorized personnel.

5. The use of accessory equipment and replacement parts not recommended by IOTA Engineering, LLC may
cause an unsafe condition and void the warranty.

6. The AC voltage rating of this equipment is specified on the product label. Do not connect the
IIS-550-I equipment to any other voltage.

7. Use only the battery part number specified for use with the IIS-550-I. Failure to do so may result in an un
safe condition, will void warranty, and result in non-compliance with UL specifications.

8. The IIS-550-I uses sealed valve regulated lead acid batteries. Batteries can be punctured if not handled
properly, therefore use caution when servicing batteries. In the event battery acid comes in contact with
eyes or skin, flush with fresh water and consult a physician immediately.

9. Install in accordance with the National Electrical Code and local regulations.

10. Installation and servicing should be performed by qualified personnel.

11. Electricians and end-users need to ensure product system compatibility before final installation.

SAVE THESE INSTRUCTIONS

THIS UNIT CONTAINS A

RECHARGEABLE VALVE-REGULATED

LEAD ACID BATTERY. PLEASE

RECYCLE OR DISPOSE OF

PROPERLY.

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

1) Remove the front cover of the IIS-550-I 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 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 IIS-550-I must be mounted securely. Do not rely on the junction box for supporting the

weight of the unit. Mount the IIS-550 securely to the wall using the keyhole slots provided.

ALWAYS CONSULT LOCAL CODES FOR STRUCTURAL REQUIREMENTS WHEN MOUNTING THE UNIT.

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 Figure 1 and STEP 2 below.

DO NOT ENERGIZE THE CIRCUIT AT THIS TIME.

2. CONNECTING REMOTE EMERGENCY FIXTURES (FIGURE 1)

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. When making connections to the IIS-

550-I, 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 Figure 1.

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 sup­ply line feeding the input wires. Refer to Figure 1.
