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:
x Remove all metallic jewelry, such as watches, rings, metal rimmed glasses, or necklaces.
x Wear safety glasses with side shields at all times during installation.
x 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
x Battery Installation and servicing should be performed or supervised by personnel knowledgeable about
batteries and the required precautions performed.
x Be extra cautious when connecting or adjusting battery cabling. An improperly connected battery cable or an
unconnected battery cable can result in arching, fire or explosion.
x Before attaching the batteries to the Alpha FXM350 or Micro350, make sure that the polarity is correct.
x Use new batteries when installing a new unit. Verify that al batteries are the same type with identical date
codes
x When replacing batteries, use sealed lead acid batteries, rated 12 V. Never install old or untested batteries
x Batteries that show signs of cracking, leaking or swelling must be replaced immediately by authorized
personnel using a battery of identical type and rating.
CAUTION: Never open, damage or mutilate batteries. Released Electrolyte is harmful to the skin
and eyes. It may be toxic and hazardous to the environment.
x Never dispose of batteries in a fire. The batteries may explode. Follow the manufacturer’s directions and
check with your local jurisdictions for safe battery disposal.
x If electrolyte splashes on your skin, immediately wash the affected area with water. If electrolyte gets into your
eyes, wash them for at least 10 minutes with clean running water or special neutralizing eye wash solution.
Seek medical attention at once.
x Neutralize spilled electrolyte with special neutralizing solution and a “spill kit” or solution of 1 lbs (0.45KG) of
baking soda (bicarbonate of soda) in 1 gallon (3.8 L) of water.
CAUTION: A battery can present a risk of electrical shock and high short-circuit current. The
following precautions should be observed when working on batteries:
