STO line
For the STO signals, it is possible to use separate jacketed cables or a protected routing. Shielded
lines must be used in each case, The shield must be placed on both sides. The shielding of the STO
lines must be connected to earth potential over a large area on the inverter side. Earthing clips are
provided in the ZETADYN 4 for this (see

g.).
See the chapter "Safe Torque Off(STO) function" for further information.
