X1 and X2 connectors
These connectors belong to the auxiliary power supply integrated into the
main RPS power supply. This auxiliary power supply is fed through connec-
tor X1.
This electrical power is received from the three-phase line to the power
supply connected to a point before the power connection operation (before
power contactor - KM1). It admits a voltage between 400 and 460 V AC.
The following table shows the values for gap, tightening torque, sections
of the screws and other data of the plug-in connector for X1.
At the same time, pin 1 of connector X2 outputs 24 V DC, 8 A to feed the
control circuits of the module itself and of the modular drives connected to
the bus.
