Wiring example with self-driven line contactor (recommended)
! Notice: When an emergency battery disconnect switch is fitted, the key switch must be fed through an auxiliary
switch to prevent over voltage damage due to disconnect during regen.
! Notice: No load other than the DMC Controller should be connected under the line contactor (between line
contactor output and B+ terminal).
Wiring example with external line contactor management
! Notice: the above scheme has to be followed strictly. Any variation must be agreed with DMC engineering first.
