5.2 Maintenance connector for high-voltage
system - TW-
The maintenance connector for high-voltage system - TW- -1- is
an electrical bridge between the two battery banks of the hybrid
battery unit - AX1- .
When the maintenance connector for high-voltage system - TW-
is unplugged, the link between the battery banks is disconnected
and the remaining voltage in the high-voltage system dissipates.
The system is de-energised at this point.
The maintenance connector for high-voltage system - TW- is al‐
ways unplugged if the high-voltage system needs to be de-ener‐
gised ⇒ page 9 .
