5.7 Central Braking Modules
Parallel connection of Central Braking Modules
To increase the braking power, it is permissible for Central Braking Modules to be connected
in parallel under the following conditions:
● Only Central Braking Modules of the same rating may be connected in parallel.
● A separate braking resistor must be connected to each Central Braking Module.
● Asymmetric load distribution (possibly tolerance-related) will result in a drop of 10% in
● The maximum number of Central Braking Modules per DC busbar should be limited to
5.7.3

Description
The Central Braking Module has the following interfaces:
● Control terminals (Disable/Reset, Ready, Fault)
● Braking resistor connection
● Reset key
● Threshold switch
● Braking resistor monitoring
● Switch-on ratio of the braking resistor
240
terms of the total braking power provided by the Central Braking Modules that are
connected in parallel.
four with regard to the power split. Higher numbers are in principle available on request
after the boundary conditions have been checked on a case-for-case basis.
