Instruction Manual
Thank you for your purchase of the Larson Electronics HALS-48-2L-LED Hazardous Location LED Light. Please follow
the steps below in order to operate and maintain this product.
WARNING!
1. TO PREVENT RISK OF ELECTRICAL SHOCK DEACTIVATE/DISCONNECT POWER SUPPLY BEFORE
INSTALLING, MAINTAINING OR RELAMPING FIXTURE.
2. DO NOT INSTALL WHERE THE MARKED OPERATING TEMPERATURE EXCEEDS THE IGNITION
TEMPERATURE OF THE HAZARDOUS ATMOSPHERE(S). KEEP TIGHTLY CLOSED WHEN IN OPERATION.
3. THIS FIXTURE SHOULD BE INSTALLED BY QUALIFIED TECHNICIANS IN STRICT ACCORDANCE WITH THE
NATIONAL ELECTRICAL CODE AND ANY LOCAL REQUIREMENTS.
INSTALLATION
This fixture can be installed directly to any flat surface using the mounting brackets provided. For installation on structural
members like beams, angles or channels, it may be necessary to install beam clamps on the mounting brackets.
1. Install fixture to mounting surface at mounting locations (mounting hardware not included).
2. For supply connection, use wire suitable for at least 90°C
3. Connect black lead to the incoming line lead, white lead to incoming neutral and green lead to incoming ground lead.
Voltage must match product label!
4. Use the wiring diagram printed on the ballast label for reference.
To change lamp, release latches to remove front lens from fixture. Keep hold of lens when removing!
Remove old lamps and replace with compatible lamps matching fixture ratings. Tighten latches.
MAINTENANCE
Electrical and mechanical inspection of all components must be performed on a regularly scheduled basic, determined by
the environment and frequency of use. It is recommended that inspection be performed a minimum of once a year.
WARNING: ELECTRICAL POWER SUPPLY MUST BE “OFF” BEFORE AND DURING INSTALLATION AND
MAINTENANCE. INSTALLATION AND MAINTENANCE PROCEDURE MUST BE PERFORMED BY A TRAINED AND
COMPETENT ELECTRICIAN.
1. Inspect all contact wire terminals for tightness. Discoloration due to excessive heat is an indicator of a possible
problem and should be thoroughly investigated and repaired as necessary.
2. Inspect contacts for signs of wear and replace if necessary.
3. Clean exterior surfaces making sure nameplates remain legible.
If any part of the light appears to be missing, broken, or show signs of damage—discontinue use immediately! This
condition could cause serious or fatal personal injury due to electrocution and/or equipment damage. Repair with the
proper replacement part(s) before continuing service.

EMERGENCY BACKUP BALLAST OPERATION
During normal operation, AC power is supplied to the ballast through the backup micro inverter and the inverter charges
the battery. Connecting the inverter wires (red and white) enables the emergency circuit and supplies power to the
control/monitor circuit. The backup micro inverter detects AC input voltage (120-277V AC) and automatically set the
output voltage during emergency operation.
When AC power fails, the backup micro inverter automatically switches to emergency mode, keeping the load illuminated
for a minimum of 90 minutes. When AC power is restored, the backup micro inverter returns to charge mode to recharge
the battery. The backup micro inverter consists of a low- battery voltage disconnect which is reset when AC power is
restored. The unit can also detect an abnormal load condition (open or shorted load) during emergency mode operation
and will protect the inverter from damage.
