Electrical connection
The electrical connection of the device must be carried out according to the respective country specific
standards.
Incorrect installation or adjustment could cause applicationally conditioned risks.
Potential equalization - earthing
The device must be grounded.
The metallic parts of the device are electrically connected with the socket of the plug M12.
Connection cable
Use only shielded signal and measurement wires and install these wires separated from power leading
wires.
Connect the cable shield of a connected cable only at one side to earth, ideally at the installation place
of the device.
Supply voltage
The voltage applied to the terminal contacts may not exceed the maximum permitted supply voltage
to avoid damage of the electronic.
The maximum permitted supply voltage range at the respective setting is:
Signal 0/4…20mA
9…33V
DC
Signal 0…10V
14…35V
DC
All connections are reverse polarity protected.
Load resistor
Signal 4…20 mA
A load resistor, e.g. the measuring shunt of an evaluation device, requires a minimum supply voltage.
Dependent on the connected supply voltage, it results in a maximum value for this resistor, where a
correct function is still possible.
This resistor can be calculated by the following term:
R
Lmax
= (U
S
- 7 V) / 20mA
R
Lmax
= maximum load resistor
U
S
= connected supply voltage
