1.3 Electrical Safety
WARNING!
WARNING!
Before working with any live battery or power system, follow these precautions:
a. Remove all metallic jewelry, such as watches, rings, metal rimmed glasses, or necklaces.
b. Wear safety glasses with side shields at all times during the installation.
c. Use OSHA approved insulated hand tools. Do not rest tools on top of batteries.
Lethal voltages are present within the 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 installa-
tion or removal procedure.
Follow battery manufacturer’s safety recommendations when working around battery
systems. Do not smoke or introduce an open flame when batteries (especially vented
batteries) are charging. When charging, batteries vent hydrogen gas, which can explode.
WARNING!
Hazardous voltages are present at the input of power systems. The DC output from rec-
tifiers and batteries, though not dangerous in voltage, has a high short-circuit current
capacity that may cause severe burns and electrical arcing.
• 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 before 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.
• The enclosure which contains the DC or AC power system must remain locked at all times, except
when authorized service personnel are present.
• Always assume electrical connections or conductors are live. Turn off all circuit breakers and double-
check with a voltmeter before performing installation or maintenance.
•
• At high ambient temperature conditions, the internal temperature can be hot so use caution when
touching the equipment.
1.4 Battery Safety
• Never transport an enclosure with batteries installed. Batteries must ONLY be installed after the enclosure has
been securely set in place at its permanent installation location. Transporting the unit with batteries installed may
cause a short circuit, fire, explosion, and/or damage to the battery pack, enclosure and installed equipment.
• Servicing and connection of batteries must be performed by, or under the direct supervision of, person-
nel knowledgeable of batteries and the required safety precautions.
• 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.
• Batteries are hazardous to the environment and should be disposed at a recycling facility. Consult the battery
manufacturer for recommended local authorized recyclers.
