Safety Precautions, continued
Do not allow live battery wires to contact the enclosure chassis. Shorting battery wires can result in a fire
•
or possible explosion.
Always replace batteries with those of an identical type and rating. Never install old or untested batteries.
•
Avoid using uninsulated tools or other conductive materials when handling batteries or working inside the
•
enclosure.
Remove all rings, watches and other jewelry before servicing batteries.
•
Spent or damaged batteries are environmentally unsafe. Always recycle used batteries. Refer to local
•
codes for proper disposition of batteries
The XM2-300HP has been investigated by regulatory authorities for use in various Alpha enclosures. If
•
you are using a non-Alpha enclosure, it is your responsibility to ensure your combination conforms to your
local regulatory requirements, and that the XM2-300HP power supply remains within its environmental
specifications.
Battery Safety Notes
Always refer to the battery manufacturer’s recommendation for selecting correct “FLOAT” and “ACCEPT”
•
charge voltages. Failure to do so can damage the batteries.
Verify the Power Supply’s battery charger “FLOAT” and “ACCEPT” charger voltage settings.
•
Batteries are temperature sensitive. During extremely cold conditions, a battery’s charge acceptance
•
is reduced and requires a higher charge voltage; during extremely hot conditions, a battery’s charge
acceptance is increased and requires a lower charge voltage. To compensate for changes in temperature,
the battery charger used in the power supply is temperature compensating.
If the batteries appear to be overcharged or undercharged, first check for defective batteries and then
•
verify the correct charger voltage settings.
To ensure optimum performance, inspect batteries every three to six months for signs of cracking, leaking
•
or unusual swelling (note that some swelling is normal).
Check battery terminals and connecting wires. Clean battery terminal connectors periodically and
•
retighten to approximately 110 inch-pounds (or to manufacturer’s specifications if not AlphaCell). Spray
the terminals with an approved battery terminal coating such as NCP-2.
Check battery voltages UNDER LOAD. Use a load tester if available.
•
Refer to the battery manufacturer’s recommendation for correct charger voltages and the power supply
•
operation manual for corresponding charger settings.
Establish and maintain a battery maintenance log.
•
Always verify proper polarity of cables before connecting the batteries to the power module. The batteries are
clearly marked for polarity. If the cables become interchanged at the battery the power supply will not operate
in inverter mode.
