1
The module must be mounted on a grounded metal frame. The S7-200 must be grounded directly over
the metal frame. With the exception of the 24 V power supply line, shielded cable must be used for all
lines. The cable shielding must be grounded on both ends at low resistance.
2
The S7-200 must be installed in a closed metal housing. For all cables, shielded cable must be used. The
cable shielding must be grounded on both ends at low resistance.
3
To meet requirements, an external protection element should be used (e.g.: Blitzductor VT
AD24V, by Dehn&Söhne)
