WARNING
•
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 BMMD, as this may short circuit the battery or bypass
the internal LVD circuitry in the BMMD.
•
Use wire and connectors appropriately rated for the highest
possible system current when making connections to the
battery, BMMD, 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 BMMD breaker turned off until the software has been
configured (see Section 3.2.2 or Section 4.5.2).
The BMMD dual breaker module provides a convenient and safe way to
connect an external lead-acid or lithium-ion backup battery to the Hybrid
Ultra. A 100-amp hydraulic-magnetic circuit breaker provides overcurrent
protection, while an internal 150-amp 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.
