5.10 Connection of an external braking resistor
The COMBIVERT P6 provides internal braking resistors as standard.
If the COMBIVERT P6 is equipped with the option "for external braking resistor", the
braking resistor must be connected with shielded cable at RB+ und RB-.
NOTICE
Only intrinsically safe braking resistors permitted !
Only "intrinsically safe" braking resistors are permitted, as these inter-
rupt themselves like a fuse, in case of fault, without the risk of fire.

NOTICE
Damage by overvoltages !
Overvoltage protection must be installed in the power supply of the
heater to limit overvoltages to values for category II (
).
The COMBIVERT P6 contains the heater elements only. The control and mon-
itoring suitable for the application must be carried out by the customer by the
heater contactor K2.
