IMPORTANT SAFEGUARDS
When using electrical equipment, basic safety precautions should always be followed including the following:
1. READ AND FOLLOW ALL SAFETY INSTRUCTIONS
2. Disconnect power before performing work on electrical equipment.
3. Do not use outdoors.
4. Do not let power cords touch hot surfaces and do not mount near gas or electric heaters.
5. Use caution when servicing batteries. Battery acid can cause burns to skin and eyes. If acid is spilled on skin or
eyes, flush with fresh water and contact a physician immediately.
6. Equipment should be mounted in locations and/or at heights where unauthorized personnel will not readily subject it
to tampering.
7. The use of replacement parts or accessory equipment not furnished by Beluce Canada Inc., may cause equipment
failure and will void the warranty.
8. Do not use this equipment for other than its intended purpose.
9. Servicing of this equipment should be performed by qualified service personnel.
10. SAVE THESE INSTRUCTIONS!

Input/Output:
120VAC / 120VAC, 60Hz
NO transformer if both input and output voltages are 120V
Batteries MUST be connected for Inverter to turn ON
N-ON (Normally ON): unit will always provide AC output to lighting load when AC input is available, and during AC input failure
N-OFF (Normally OFF): unit will provide AC output to lighting load only when AC supply input fails
MAXIMUM SURGE VALUES: Inrush / Peak current factor of the lighting load should be considered while sizing
lighting load for the inverter

CAUTION
1. Verify on Lighting load wiring that the neutral conductor IS NOT BONDED OR CONNECTED to the ground wiring.
2. Inverter’s AC output MUST be wired by its own line and neutral wires. DO NOT connect the AC output neutral wire
to any neutral wires in the building.
3. If more than one inverter is installed, DO NOT CONNECT the neutrals of multiple AC outputs together.
4. DO NOT CONNECT the AC output line and neutral to the mains AC input line and neutral.
5. Observe battery polarity. RED is “+” POSITIVE and BLACK is “-” NEGATIVE.
6. The battery charging current has been factory set. DO NOT adjust it.
7. Disconnect ALL electrical sources including the inverter’s AC and DC inputs before servicing.
MAINTENANCE
1. Allow 24 hours recharge time after installation or power failure before full load testing.
NOTE: DO NOT LEAVE BATTERIES CONNECTED TO INVERTER, WITHOUT AC INPUT SUPPLIED OR WITH
UNIT SHUTDOWN, FOR A LONG DURATION.
2. Batteries may stop charging if unit detects a fault / error code; seek qualified support as soon as possible.
3. Beluce Canada Inc. recommends that the equipment be tested and that written records be maintained according to
the local building code.

INSTALLATION
Airflow is vital to the performance of this product.
Install with AT LEAST 12" (30cm / 300mm) clear space on both ends and do not block ventilation holes.
1. Extend un-switched 24-hour AC supply of rated voltage to the unit, installed in accordance with all applicable codes
and standards. This circuit should NOT be energized/live at the time.
2. Unscrew the cover screws on the sides of the unit. Lift and remove the front cover .
3. Knockouts are stamped into the back and side of the cabinet. Knock out the appropriate hole(s) and bring wires
through them into the cabinet.
4. Mount the unit securely into place. This unit is FLOOR MOUNT ONLY!
5. Make proper wiring connections between the AC supply and terminal blocks within the unit (see AC Wiring
diagram, page 2).
6. Make proper load connection to the terminal block (see AC wiring diagram above).
7. Batteries are shipped separately. Install batteries into the cabinet and complete the appropriate connection:
Red wire to positive battery terminal (+) and Black wire to negative battery terminal (-).
8. Route wires and secure in place.
9. Select Load Operation Mode (N-ON / N-OFF) from the internal toggle switch .
10. Replace cover and secure with cover screws .
11. Turn on AC line voltage supply.
UNIT RESET
1. Disconnect AC input, disconnect batteries from inverter, disconnect load.
2. Wait 10 seconds; measure battery voltage during wait period to verify condition.
3. Reconnect batteries, and then reconnect AC input.
4. If unit turns ON with no error notifications, turn OFF unit with power button and disconnect AC before reconnecting
lighting load.
TROUBLESHOOTING
Problems Reasons Solutions
No AC output voltage
during emergency
Surge (or inrush) of lighting load exceeds
inverter’s maximum, causing unit shutdown
• Reduce number of connected lighting
fixtures, or replace with lower-surge
fixtures
• Reset unit
No AC output voltage,
with AC input present
(N-ON mode only)
Lighting load exceeds inverter’s maximum
capacity, causing unit shutdown
• Reduce number of connected lighting
fixtures
• Reset unit
Short-circuit, causing AC output circuit
breaker to trip
• Locate and clear short-circuit
• Reset circuit breaker located on inverter
box inside the unit enclosure
Unit does not turn ON,
with AC input present
Battery voltage is lower than acceptable
threshold
• Disconnect battery and recharge by
separate means; battery may need
replacement
Battery is not connected to inverter box • Connect 12V battery terminals to
inverter
Unit does not last up to
required emergency
duration
Battery is not fully charged • Allow battery recharge for up to 24
hours
Lighting load exceeds unit rating • Reduce number of connected lighting
fixtures to below unit power rating
Batteries are defective, or aging • Replace batteries
