3.5.1 Connecting the sensor cable to the signal converter
The pH sensors are available without internal Pt100 temperature sensor. The pH sensors
without internal Pt100 temperature are connected to the signal converter using a coax 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.
