PS4-200 (left-hand socket) using the
programming cable ZB4-303-KB1.

Jumpers
If identical ground potentials cannot be achieved,
either connect the PC to the mains supply via an
isolating transformer or use a laptop powered by an
internal battery.

Warning!
In order to avoid potential equalization currents
between the PLC and the PC, devices attached
to the PRG and Suconet K interfaces must have
the same ground potential. If the ground
potentials differ, the interfaces can be destroyed.
