Larson Electronics ITX-40 Instruction Manual

WARNING:
READ CAREFULLY BEFORE INSTALLING FIXTURE. RETAIN THESE INSTRUCTIONS FOR FUTURE REFERENCE.
CRITICAL SAFETY INSTRUCTIONS:
• INSTALLATION SHOULD ONLY BE CONDUCTED BY A QUALIFIED ELECTRICIAN IN ACCORDANCE WITH
NEC AND ANY RELEVANT LOCAL BUILDING CODES.
• RISK OF FIRE OR ELECTRIC SHOCK. FIXTURE INSTALLATION REQUIRES KNOWLEDGE OF FIXTURE'S
ELECTRICAL SYSTEMS. IF NOT QUALIFIED, CONTACT A QUALIFIED ELECTRICIAN.
• BE CERTAIN ELECTRICAL POWER IS OFF BEFORE AND DURING INSTALLATION AND MAINTENANCE.
• MAKE SURE THE SUPPLY VOLTAGE IS THE SAME AS THE FIXTURE'S RATED VOLTAGE.
• TO PREVENT WIRING DAMAGE OR ABRASION, DO NOT EXPOSE WIRING TO EDGES OF SHEET METAL OR
SHARP OBJECTS. SUITABLE FOR DAMP LOCATIONS.
The Larson Electronics ITX-40 Single Output Power Supply is designed to convert commonly used AC electrical current
to 12VDC @ 40 amps or 24VDC @ 20 amps (voltage selectable below). This unit features forced air cooling by built-in
fan, high power density of 4.9w/in3 and a built-in remote sense function. The device may be used to convert mainstream
AC voltages to 12VDC or 24VDC, to operate a wide range of equipment, such as LED lights and other electronics with
low voltage DC requirements.
Installation
•
Before any installation or maintenance work, please disconnect
your system from the utility. Ensure that it can't be re-connected
inadvertently!
•
Keep enough insulation distance between mounting screws and
internal components of power supplies. Please refer to case
drawing on specifications to receive the maximum length of
mounting screw.
•
Mounting orientations other than standard orientation or operate
under high ambient temperature may increase the internal
component temperature and will require a de-rating in output
current. Please refer to the specification sheets to receive the
optimum mounting position and information about the de-rating
curve.
•
Fans and ventilation holes must be kept free from any
obstructions. Also a 10-15 cm clearance must be kept when the
adjacent device is a heat source.
•

If above mentioned suggested torque is not sufficient due to special application, then Nylok Blue Patch screws can be
used, and more torque can be added if needed.
