HBC-series V7 LV+MV
When is used additional capacitors for HBC 25063-3 (140120-3)
controller, necessary using this connecting with
external antispark resistor.
*)
The possibility of emergency disconnecting by using
BMS-2 system
(output
PO 1
of the
BMS-2
unit).
In this case, it is necessary to cancel the jumper
K20/2 to K20/4.
To indicate turn-on the main power contactor
(= traction power supply connection) can be used
either bulb 12V / or 1 to 5W LED with
corresponding serial resistor.
