WARNING
•
Handle batteries with care, never short circuit the 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 — one of which will be connected with
the BMM BAT terminal.
•
Note that the BAT terminal on the BMM is tied internally to
either the (+) or (−) shelf output through the LVD contactor,
depending on the polarity of the power system used.
•
Check shelf model polarity before connecting a battery to
the BMM.
•
Only use the Equalize Charge setting for flooded lead-acid
batteries in a well-ventilated location. Do not use Equalize
Charge on sealed batteries. Always consult with battery
manufacturer and observe all battery manufacturer
recommendations.
•
Do not tie either of the unit’s main outputs to the BAT
terminal on the BMM, as this may short circuit the battery or
will bypass the internal LVD circuitry in the BMM.
•
Do not ground both the load and battery as this may bypass
the internal LVD circuitry or create a short circuit to the
system.
•
Use wire and connectors appropriately rated for the highest
possible system current when making connections to the
battery, BMM, and unit.
•
If a lithium-ion battery is used, it must utilize an integrated
battery management system (BMS) to protect the battery
cells from inappropriate voltage or current levels.
CAUTION
Leave BMM breaker turned off until the software has been
configured (see Section 3.2.3 or Section 4.2.2).
4.4.1 STATUS
