1. CONNECTING THE BATTERY CHARGER INPUT (FIGURE 1)
Battery Charger Input leads serve as your normal power sense and charging input for the battery. They require
unswitched
AC
input of 120 or 277 VAC. If a local switch is present on the designated emergency circuit, the battery charger input leads must
be wired ahead of the switch.
A.
For 120V
supply, connect the AC line wire to the BLACK Battery Charger Input lead.
For 277V
supply, connect the AC
line wire to the ORANGE Battery Charger Input lead.
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 Battery Charger Input lead.
C. Connect the ground wire in accordance with local and national codes. A GREEN wire is provided for this purpose.
2. CONNECTING THE NORMAL AC INPUT (FIGURE 1)
Normal AC Input leads allow for your fixture(s) to operate in normal power situations while maintaining emergency
capabilities. Before connecting the Normal AC Input leads, see
Figure 1
to determine which normal power situation best
fits your application. In all applications:
A.
For 120V
supply, connect AC line input to the BLACK Normal AC Input lead.
For 277V
supply, connect the AC line
input to the ORANGE Normal AC Input lead.
Cap the unused lead.
B. Connect the AC line Neutral to the WHITE Normal AC Input lead.
3. CONNECTING EMERGENCY FIXTURES (FIGURE 1)
A. Connect emergency fixtures to the output leads 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
IIS 550 I
.
When making connections to the IIS 550 I, DO NOT connect the Input Neutral (WHITE) to the Output
Neutral (GRAY).
B Connect the Fixture Supply Ground to the
IIS 550 I
Ground.
Consult the
IIS 550 I
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 (FIGURE 2)
A. 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 5, make sure that all unused wires are properly capped.
Failure to do so may result in an unsafe condition and equipment failure.
5. INSTALLING THE BATTERY (FIGURE 2)
ATTENTION:
Use only battery part number
IIS 550 I BAT
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.
Battery Torque Ratings:
initial torque is 65 in/lbs, annual is 52 in/lbs.
B. Install the battery into the
IIS 550 I
with the terminal posts facing toward the front of the unit. NOTE: The
IIS 550 I
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 IOTA Engineering
Customer Service to purchase this accessory if needed.
