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:
● A separate braking resistor must be connected to each Central Braking Module.
● Only Central Braking Modules of the same rating may be connected in parallel.
● Asymmetric load distribution (possibly tolerance-related) will result in a drop of 10% in
