Functional earth (FE)

Ground the FE wire of the supply line connected to X70.

The FE potential is forwarded to the FE pin of X71. If several devices are connected in series, only the FE wire of the first supply line must therefore be grounded.

EP7402-0057

You can tap the FE potential at the connector housings of X70 and X71: use the nuts of X70 and X71 to screw on a metal sheet. In this way, EP7402-0057 can be connected to the grounded machine bed.

EP7402-0167

The EP7402-0167 has a separate ground connection. See chapter FE connection (EP7402-0167 only).
