3.5.1 Connecting the sensor cable to the signal converter

The pH electrodes are available with or without integrated Pt100 temperature sensor.
Electrodes without integrated Pt100 temperature sensor are connected to the signal converter
using a coax cable. Electrodes with integrated temperature sensor use a SixPlug cable.

When ordering the one channel version, only the interface "Pos.A" is populated. In the version
with two channels the interfaces "Pos.A" and "Pos.B" are populated.

DANGER!
All work on the electrical connections may only be carried out with the power disconnected. Take
note of the voltage data on the nameplate!

INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order.
Check for the correct supply voltage printed on the nameplate.
