1.2 General Warnings and Cautions
You must read and understand the following warnings before installing the Alpha Micro and its components. Fail-
ure to do so could result in personal injury or death.
• Read and follow all instructions included in this manual.
• Do not work alone under hazardous conditions.
• Only qualified personnel are allowed to install, operate and service this system and its components.
• Use proper lifting techniques whenever handling equipment, parts, or batteries.
• Always assume electrical connections or conductors are live. Switch off all circuit breakers and double-
check connections with a voltmeter before performing installation or maintenance.
• Place warning label(s) on the utility panel to tell emergency personnel a UPS is installed.
• The Alpha Micro uses more than one live circuit. AC power may be present at the outputs even if the system
is disconnected from line or battery power.
• The Alpha Micro’s surface can be very hot to the touch.
• Battery installation and servicing should be done or supervised by personnel knowledgeable about batteries
and their safety procedures.
• 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 a special neutralizing eye wash
solution. Seek medical attention at once.
• Neutralize spilled electrolyte with special neutralizing solutions in a “spill kit” or a solution of 1 lb. (0.45 kg) of
baking soda (bicarbonate of soda) in 1 gallon (3.8 L) of water.
• Be extra cautious when connecting or adjusting battery cabling. An improperly connected battery cable or
an unconnected battery cable can result in arcing, fire, or explosion.
• Use new batteries when installing a new unit. Verify that all batteries are the same type with identical date
codes.
• Always replace batteries with ones of identical number, type and rating. Never install old or untested batter-
ies. One sealed lead-acid battery is rated to a maximum voltage of 12 VDC.
• A battery that shows signs of cracking, leaking or swelling must be replaced immediately by authorized per-
sonnel using a battery of identical type and rating.
• Keep the chassis area clear and dust-free during and after installation.
• Keep tools away from walk areas where you or others could fall over them.
• Wear safety glasses when working under any conditions that might be hazardous to your eyes.
• Do not work on the unit or connect or disconnect cables during periods of lightning activity.
• Do not smoke or introduce sparks in the vicinity of a battery.
• Never open or damage the batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic
and hazardous to the environment.
• A battery can present a risk of electrical shock and high short-circuit current. The following precautions
should be observed when working on batteries:
a. Remove watches, rings, or other metal objects.
b. Use tools with insulated handles.
c. Wear rubber gloves and boots.
d. Do not lay tools or metal parts on top of batteries.
e. Disconnect the charging source before connecting or disconnecting battery terminals.
f. Determine if the battery is inadvertently grounded. If inadvertently grounded, remove the source from the
ground. Contact with any part of a grounded battery can result in electrical shock. The likelihood of such
shock can be reduced if the grounds are removed during installation and maintenance (applicable to
equipment and remote battery supplies not having a grounded supply circuit).
