4.2.4.2 Control of a 150...300 Vdc brake
Optional output to direct control of a brake with a rated voltage of 150...300 VDC (operating
voltage max. 420 Vdc; depending on dc link voltage).

Attention
There is no internal inrush current limiting at the terminals BT+ and BT-. Therefore energy
storages supposed to connect only, if they are discharged. Instructions for switchgear use
at these terminals and for the recommended switching sequence on request at KEB.
observance may lead to damage the switching unit or at the terminals of the COMBIVERT P6.
4.2.6

Connection of an external braking resistor

The COMBIVERT P6 provides internal braking resistors as standard. If the COMBIVERT P6
included the option "for external braking resistor", the braking resistor must be connected
with shielded cable at RB+ und RB-. If the braking resistor isn't intrinsically safe, it must be
thermically monitored.
