2. STEP-BY-STEP: SERIAL COMMUNICATION (CAN) CONNECTIONS
2.1 To connect your BMAC to a single (non-paralleled) Standard Product Range battery, simply connect the
BMAC’s BMS CAN port to any one of the two available CAN ports on the battery with a straight 1-to-1 pin
RJ45 network cable.
2.2 To connect you BMAC to a parallel battery configuration, first daisy-chain connect the batteries to each
other from any one of the available two CAN ports on each battery to the next one. This should leave one
available CAN port remaining on the first and last battery in the parallel configuration. Connect the BMAC’s
BMS CAN port to either one of the two remaining CAN ports on either battery at the end of the string with a
straight 1-to-1 pin RJ45 network cable.
2.3 The BMAC can then be connected to a serial communication-compatible inverter or peripheral device from
the BMAC’s INV CAN port to the appropriate port on the peripheral device.
IMPORTANT: The above instructions are only applicable to connections between the BMAC module and
BlueNova’s Standard Product Range. For serial communication connections between the BMAC and products
from other BlueNova product ranges (i.e. RacPower etc.), please reference the latest relevant product manuals.
