5.1.4 Mounting
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.
