WARNING
Risk of serious personal injury or damage to equipment and
property. Observe the following:
•
Use a battery with rating and capacity appropriate for the
model of power supply in use.
•
Use an appropriate DC overcurrent protection device in line
with the backup battery connection.
•
Use wire and connectors rated for the maximum load
current.
•
Ensure battery polarity is correct before connecting.
•
Do not attempt to charge a frozen battery.
•
Always install batteries in well-ventilated areas.
•
Handle batteries with care, never short circuit battery
terminals.
•
Always consult with battery manufacturer and observe all
battery manufacturer recommendations.
•
When connecting a battery, ensure the nominal battery
voltage is correct, and that the battery positive is connected
to a positive terminal and the battery negative is connected
to a negative terminal.
•
Note that the BAT terminal on the BMMD is internally tied to
either the (+) or (−) system output through the LVD
contactor, depending on the polarity of the power system
used.
•
Check system model polarity before connecting a battery to
the BMMD.
