Installation 6-21
Be sure to connect the feed and return cable shields to the shield
connections on the metal connection box.
When necessary, extend sensors with the 30-foot (10-m) fixed cable using A2Y(L)2Y
with “X“ • 2 • 0,8 alternatively. X represents the number of wire pairs, depending on
length of the line. Leave 15 percent of the wire for reserve.
Use a single wire to extend each signal line (RxTx).
To extend the power supply UE and earth UE-GND, use one or more parallel
connected wires per line, depending on the distance.
The following table lists the minimum number of wires per connection. Two
required: 1x for UE + and 1x for UE-GND.

*Solder the parallel wires for UE + and GND together based on the supply line.
Equivalent extension cables with other cross-sectional areas are available upon
request.
Connection boxes used to extend cables must be metal. Always
connect the feed and return cable shields to the shield connections
on the metal connection box.
Establishing improper connections that create higher transition
resistance or using other cables may lead to signal disruptions and
erroneous measurements.
