The braking resistor for all modules is connected at terminals DCP/R1 and R2. Since it
generates heat, it should be mounted to the side of the Power Modules.
The braking resistors for the PM340 Power Modules in frame sizes FSA and FSB are
designed as base components. If the PM340 Power Modules of the FSA or FSB frame size
are operated without a line reactor, the braking resistors can also be installed under the
Power Modules.
The braking resistors for the PM340 Power Modules of the FSC to FSF frame sizes should
be placed outside the control cabinet or the switchgear room to lead the resulting heat loss
away from the Power Modules. This reduces the level of air conditioning required.
The braking resistors can be installed horizontally or vertically. The power connections on
vertically installed resistors must be at the bottom.

Note
PE connection
The PE connection for the braking resistor is established via the shield connection for
frame
For installation according to EN 60204
-1 and EN 61800-5-1, the PE connection on the
housing must be used. The PE conductor in the pigtail is, in this case, not to be used, but
can be suitably tied off or cut off.
