3 Installation
k To achieve a good shielding effect for the cable, only use cables that have
shielding made with tinned or nickel-plated copper braiding. The coverage
of the shielding should be at least 70%; the lay angle should be 90°.
Screens made of steel braiding are not suitable. Earth the shielding of the
load cable on both ends.
k The shielding of the control inputs must only be earthed at one end (IPC
side). If potential differences exist, install an additional equipotential
bonding conductor.
EMV compliant
design The user/owner is responsible for compliance of the specific application with
the EMC directive. The diagram below illustrates such a design for type
709050/X3-12-400-XXX-200/XXX with a Phase / Phase supply configuration.
