The number of anti-condensation heaters is set in accordance with the number of cabinet
panels.
The converter monitors and signals if the external supply for the anti-condensation heating fails.

3.9.18 EMERGENCY STOP Category 0 (option L66)
The Emergency mushroom-head pushbutton is connected with the safety relay.
The circuit-breaker disconnects the power supply to the converter. The motor coasts down.
Because not all auxiliary circuits are disconnected when you press the mushroom-head
pushbutton, you must switch off the auxiliary power supply at the plant. Otherwise the pre-
charging device or the pre-magnetization equipment (when present) can cause medium-
voltage (>1 kV) to be present in the converter.

3.9.19 Braking Module (option L72)
Using a connected braking resistor, the Braking Module prevents an overvoltage condition in
the DC link. The braking resistor is not part of the scope of supply of the Braking Module. You
must externally mount the braking resistor.
The Braking Module employing M2C technology consists of identical power cells connected in
series. The number of cells in the Braking Module is equal to the number of cells in one branch
of the Motor Module. For example, a Motor Module with 36 cells has a Braking Module with 6
cells.
