Option 2 - Parallel operation:
▪
The entire system consists of a minimum of two and a maximum of four parallel
•
battery systems.
The drive connector of the first battery system is connected to the
•
vehicle/charger as in Figure 3.
The connector for termination of the first battery system is connected to the drive
•
connector of the second parallel battery system. The connector for the
termination of the second parallel battery system again with the drive connector
of the third parallel battery system and so on.
The termination plug of the last parallel battery system (maximum 4) is
•
connected to the supplied termination for parallel operation.
Figure 3 shows the wiring of the entire system with n individual battery systems
•
in parallel operation.

GROUNDING CONCEPT
The ground of the battery electronics is internally referenced to the battery negative potential.
The customer must ensure that the housing is externally grounded to the same potential
(battery minus potential) by means of a potential equalization cable.
