The protective conductor connection must be in compliance with national regulations. As a
minimum, the cross-section required is the cross-section of the line feeder cable of the assigned
devices.
USB upstream port X125
Interface X125 is implemented as "high powered interface" (5 V/ 500 mA). As a consequence,
the X125 can only be connected to USB interfaces which have their own power supply and
whose downstream ports are capable of supplying a 500 mA current. A standard USB 2.0 Hi-
Speed cable of max. 3 m long (recommended: 1.5 m) is supported.
