Electrical safety
WARNING: Hazardous voltages are present at the input of power systems. 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:
•
Remove all metallic jewelry, such as watches, rings, metal rimmed glasses, or necklaces.
• Wear safety glasses with side shields at all times during installation.
• Use OSHA approved insulated hand tools.
DANGER: Lethal voltages are present within a power system. Always assume that an electrical
connection or conductor is energized. Check the circuit with a voltmeter with respect to the grounded
portion of the enclosure (both AC and DC) before performing 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 240 Vac. Ensure that the utility power is disconnected and locked out performing any installation or
removal procedure.
Ensure that no liquids or wet clothes come into contact with internal components.
Hazardous electrically live parts inside this unit are energized from the batteries even when the AC input power is
disconnected.
Battery safety
Servicing and connection of batteries must 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 your hands and neck.
Use OSHA approved insulated hand tools. Do not rest tools on top of batteries.
Batteries contain or emit chemicals known to cause cancer and birth defects or other reproductive harm. Battery
post terminals and related accessories contain lead and lead compounds. Wash your hands after handling
batteries.
WARNING: Follow battery manufacturer’s safety recommendations when working around battery
systems.
WARNING: Do not smoke or introduce an open flame when batteries (especially vented batteries) are
charging. Batteries vent hydrogen gas when charging, 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 the conduits and removing any knockouts to accommodate conduit locations, ensure that any gaps
between the conduit fittings and the shroud are sealed. Apply a weatherproof caulking to gaps to prevent wind
driven rain from reaching the electrical equipment.
