.
Tightening torque: <1Nm.
Cable: double insulated, UL 94 V-1 flammability classification and
VW-1 flame rating.
Ferrule: certified, 1.5 mm

conductor area with 14 mm overall
length and 8 mm pin length.
Connector pins:
• PW: 24VDC power output to the sensor,
• S: signal input,
• COM: internal common reference point of Sensformer
Connectivity Device.
4. Connect the PT100 temperature sensor
Do not use the cables without ferrules. The ferrules must be
certified.
For more information, see the Installation
requirements chapter.
The using cables on the PT100 input must be double insulated
and must have UL 94 V-1 flammability classification and VW-1
flame rating.
For more information, see the Installation
requirements chapter.
Connect the PT100 sensors to the PT100 input of the Sensformer
Connectivity Device.

conductor area with 14 mm overall
length and 8 mm pin length.
Connector pins:
• PW: power output with 1mA current to the PT100 sensors.
• S+: positive signal point,
• S-: negative signal point,
• FSH: shielding point which is connected to the internal
common reference point (COM).
5. Connect antennas
Connect the antennas to the SMA ports of the Sensformer
Connectivity Device. Check the label on the cables. For proper
functionality, the cables must be connected to the appropriate
ports.
Figure 7 – Example for connecting antennas
6. Connect the ModBus device
Do not use the cables without ferrules. The ferrules must be
certified.
For more information, see the Installation
requirements chapter.
The using cables on the RS485 communication port must be
double insulated and must have UL 94 V-1 flammability
classification and VW-1 flame rating.
For more information, see the Installation
requirements chapter.
The Sensformer Connectivity Device cans communication on
ModBus. It is a three-pole screw terminal (D+, D- and COM). If it
is necessary, wired up the ModBus port. For example:
