Wiring of the BMS to the CMEV.4eHT
(See Figure 6)
1)
Remove the three screws connecting the lid.
2)
Carefully remove the lid to expose the PCB.
3)
Carefully pierce through the ‘closed’ top hole within the lids cable grommet and pass through the BMS
cable (not provided).
4)
Remove the internal cable clamp in readiness for the BMS wiring.
5)
Using a 5 or 6 core cable, sized between 0.326mm

, insert wires into the BMS terminal
block on the PCB (as per table 1.2 below). Pin 2 is a volt free contact for additional sensors.
6)
Secure the cable within the internal cable clamp provided.
7)
Carefully realign the lid to the ‘pot controls’ and respective screw connections and secure with the three
connecting screws.
