A. Safety Measures
You must know whether your heliport lighting system is powered by AC or DC before
installing the fixture. AC models work on either 120VAC or 240VAC if Halogen or on a
range of 100 to 240VAC if LED. DC models operate from 10 to 30VDC. The lights are
designed to be installed in a parallel circuit, which maintains a constant voltage and
brightness for all lights.
Ensure power is off before installing or servicing heliport fixtures!
Follow the local NEC code!
Make sure the equipment is rated and approved for the environment in which you are
intending to use it. Do not operate this equipment in humid, flammable, or explosive
environments unless it has been rated for safe operation in these environments.
Use only electrical wire of sufficient gauge and insulation to handle the rated current and
voltage demand.
Route electrical wiring along a protected path. Make sure they will not be damaged by
moving equipment.
Protect components from harsh environment conditions.
Protect equipment with safety devices as specified by applicable safety regulations.
Before starting this equipment, check all safety interlocks, fire –detection systems, and
protective devices such as panels and covers. Make sure all devices are fully functional. Do
not operate the system if these devices are not working properly.
Never operate equipment with a known malfunction.
Do not attempt to operate or service electrical equipment if standing water is present.
Do not touch exposed electrical connections on equipment while the power is ON!
