WARNING
•
Note that the BAT terminal on the BMM is internally tied to
either the (+) or (−) shelf output through the LVD contactor,
depending on the polarity of the power system used.
•
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 main outputs to the BAT terminal
on the BMM, as this may short circuit the battery or 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 main DC output.
•
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 3.2.2 or Section 4.2.2).
The optional BMM, or BMMD dual breaker module, provides a convenient
and safe way to connect an external lead-acid or lithium-ion backup battery
to the Modular Power Series. A 100-amps hydraulic-magnetic circuit
breaker (BMM) provides overcurrent protection, while an internal 150-amps
LVD contactor will disconnect the battery should it discharge below a
voltage level which is set in the Battery Backup section of the GUI. Internal
battery current monitoring provides a full suite of remote battery charge
monitoring features.
1.
Check that the default system output voltage and current limit match the
requirements of the battery and the loads to be connected. Adjust the
system Output Voltage and Current Limit (see Section 3.2.1 or Section
4.2.2) to match the combined battery and system load requirements
before making final connections, if required.
