Electrical Safety
WARNING
Hazardous voltages are present at the input of a power system. The DC output from rectifiers and
batteries, though not dangerous in voltage, has a high short-circuit current capacity that may
cause severe burns and electrical arcing.
Before working with any live battery or power system, follow these precautions:
x Remove all metallic jewelry; e.g., watches, rings, metal rimmed eyeglasses, necklaces.
x Wear safety glasses with side shields (and prescription lenses if necessary) at all times during installation.
x Use OSHA approved insulated hand tools.
DANGER
Lethal voltages are present within a power system. Never assume that an electrical connection or
conductor is not energized. Check the circuit with a voltmeter with respect to the grounded
portion of the enclosure (both AC and DC) prior to any installation or removal procedure.
Do not work alone under hazardous conditions.
A licensed electrician is required to install permanently wired equipment. Input voltages can range
up to 240Vac. Ensure that utility power is disabled before beginning installation or removal.
Ensure no liquids or wet clothes contact internal components.
Hazardous electrically live parts inside this unit are energized from batteries even when the AC input power is
disconnected.
WARNING
High leakage current – Earth connection essential before connecting supply.
Battery Safety
Servicing and connection of batteries shall be performed by, or under the direct supervision of, personnel
knowledgeable of batteries and the required safety precautions.
Always wear eye protection, rubber gloves, and a protective vest when working near batteries. Remove all
metallic objects from hands and neck.
Use OSHA approved insulated hand tools. Do not rest tools on top of batteries.
Batteries contain or emit chemicals known to the State of California to cause cancer and birth defects or other
reproductive harm. Battery post terminals and related accessories contain lead and lead compounds; wash hands
after handling (California Proposition 65).
WARNING
Follow battery manufacturer’s safety recommendations when working around battery systems.
WARNING
Do not smoke or present an open flame when batteries (especially vented batteries) are on
charge. Batteries vent hydrogen gas when on charge, which creates an explosion hazard.
Batteries are hazardous to the environment and should be disposed of safely at a recycling facility. Consult the
battery manufacturer for recommended local authorized recyclers.
Post Installation Weather Proofing
After installing conduit and removing any of the knockouts to accommodate conduit locations, it is important to
ensure that any gaps between conduit fittings and the shroud are sealed when the rear shroud is re-installed.
Where gaps are present, a weatherproof caulking should be applied to ensure compliance to wind driven rain
requirements.
