An additional external 24 V power pack can be connected via the X1S2 interface. If the mains
power supply is switched off, this supplies the electronics in the 350 tightening system
(external field buses such as e.g. ProfiBus remain ready for operation).

* The external power pack at this interface is connected in parallel to the internal 24 V
power supply. The internal isolating diode ensures that with equally high supply voltages
(internal = external), the internal power supply bears the load. The power pack must be
stabiled and protected against short circuit and overload. Maximum ripple voltage
240 mV , 150 mV
