DC link connection

Connecting an external Braking Module
PM330 Power Modules permit an external Braking Module to be connected via the DCP and
DCN DC link connecting terminals.
Characteristic data of the connecting terminals (@ Uline rated 380 V – 480 V / 500 V – 600 V
/ 690 V):
● Supply voltage: up to 780 V / 970 V / 1160 V DC
● Current carrying capacity:
– At a 45 °C ambient temperature:
– At a 55 °C ambient temperature:
Supplementary rectifier for higher pulse line harmonics
When using DC link connecting terminals DCP and DCN as infeed for an external
supplementary rectifier (current carrying capability, see the appropriate table in the Technical
data), the rectifier must have as a minimum a fully-controlled 6-pulse diode three-phase
bridge or a 6-pulse thyristor three-phase bridge and a 2 % line reactor.
The system (infeed transformer, reactor, busbars, fuses, ...) must be designed so that the
current distribution of the individual subrectifiers corresponds to the theoretically expected
value.
The short-circuit and overload protection must be adapted.
Note
It is only permissible to switch on the supplementary rectifier if the DC link has been
precharged by the Power Module.
Signal X9.8:"DC Link Charged" can be used for this purpose.
