3.8 Battery connection
Bus circuit capacitor C-ZW:
560 µF at 700 V
Discharge resistance R-ZW:
50 kΩ
Series resistor:
RV approx. 40 Ω , 50 W
Charging current via K2:
< 20 A
Note:
Enable (RUN) only after the main
contactor K1 is activated.
The max. supply voltage (battery voltage) 740 V=
must not be exceeded at any time (not even for short intervals)!
Danger of damage!
Error message: OVERVOLTAGE
F1 = safety fuse
Programming of an output for the pre-charging:
The output Dout1 switches the relay K3 when the bus circuit voltage (DC-BUS) is greater than the
variable 1.
Warning:
The power supply connection has no protection against reverse polarity.
If the polarity of the connection is wrong, the device will be destroyed!
