4.2 Connecting the signal converter
Both grounding terminals 7 and 8 are equally effective from a technical point of view.
The following procedures are to be performed:
• Unscrew the housing cover 1 of the electrical terminal compartment.
• Thread the connection cable through the leadthrough in the housing.
• Connect the cable for the current output and the cable for the optional pulse output as shown
in the cable terminal diagrams below. To facilitate installation the connection plug can be
removed from the device. The plug is configured in such a way as to prevent reverse polarity.
• Connect the grounding to terminal 7 alternatively use the PE terminal on the connection
piece between measuring sensor and signal converter 8.
• Tighten the cable glands.
• Hand-tight the housing cover with gasket.
