Cable specification, connecting cable
The specifications of the cable connecting the transmitter and the sensor of the remote version are
as follows:
• 2 x 2 x 0.5 mm² (AWG 20) PVC cable with common shield (2 twisted pairs)
• Conductor resistance:
≤
40
Ω
/km [
≤
131.2
Ω
/1000 ft]
• Operating voltage:
≥
250 V
• Temperature range: –40 to +105 °C [–40 to +221 °F]
• Overall nominal diameter: 8.5 mm [0.335"]
• Maximum cable length: 100 m [328 feet]
!
Note!
• The cable must be installed securely to prevent movement
• The cable should be of sufficient diameter to provide adequate sealing of the cable gland

Warning!
• Risk of electric shock. Switch off the power supply before opening the device. Do not install or
wire the device while it is connected to the power supply. Failure to comply with this precaution
can result in irreparable damage to the electronics.
• Risk of electric shock. Connect the protective earth to the ground terminal on the housing before
the power supply is applied unless special protection measures have been taken
(e.g. galvanically isolated power supply SELV or PELV).
• Compare the specifications on the nameplate with the local supply voltage and frequency.
The national regulations governing the installation of electrical equipment also apply.
1.
Unscrew the connection compartment cover from the transmitter housing.
2.
Feed the power supply cable, the fieldbus cable and the power supply cable for external
termination (optional) cable through the appropriate cable entries.
3.

Caution!
– Risk of damage to the fieldbus cable!
Observe the information about shielding and grounding the fieldbus cable
– We recommend that the fieldbus cable not be looped using conventional cable glands.
If you later replace even just one measuring device, the bus communication will have to
be interrupted.
4.
Screw the cover of the connection compartment back onto the transmitter housing.
