. End sleeves (without
plastic collars, length 10 mm) should be used on the strands to connect the
wires to the terminals. Strands must not be tinned, irrespective of whether end
sleeves are used or not.

Plug‐in terminals
The transducer cable and the signal output cables must be shielded. The cable
shield must be connected to or to the shielding of the surrounding housing.
The shielding must be connected extensively. With other connection tech
niques, an EMC‐proof shield should be applied in the wire area and this shield
should also be connected extensively (see also HBM Greenline Information,
brochure i1577). The surrounding housing must be EMC‐proof. All cables that
lead into this housing must be shielded and/or equipped with filters.
The four plug‐in terminals are labeled with numbers to prevent confusion when
attaching them to the four sockets. The connection diagram is printed on the
housing lid as shown in the tables below.
Six‐wire configuration must be used for connecting the transducer. The factory
setting is with four‐wire configuration, see Section 5.2, Page 13.
