DCPS, DCNS connection for a dV/dt filter with Voltage Peak Limiter

Table 4- 5
With frame sizes FX and GX, the connecting cables are routed down through the Power
Module and out.
4.7.5 Adjusting the fan voltage
The power supply for the device fan (1 AC 230 V) in the Power Module is generated from the
line supply using a transformer.
The transformer is fitted with primary taps so that it can be fine-tuned to the line voltage.
If necessary, the connection fitted in the factory, shown with a dashed line, must be
reconnected to the actual line voltage.
For the position of the setting terminals, see the "Connection overview" section.
Note
Number of transformers
One transformer is installed in frame sizes FX, GX and HX; two transformers are installed in
frame size JX. The two primary terminals on these devices must be set together.
