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.
4.1
Potential equalization - earthing
The device must be grounded.
The earthing can be carried out by the process connection.
4.2
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.
4.3
Supply voltage
The voltage applied to the terminal contacts may not exceed the maximum permitted supply voltage
(see chapter „Technical data“) to avoid damage of the electronic. The connection is reverse polarity
protected.
4.4
Load resistor
4.4.1
Electronic output – 2-wire, current 4…20mA
A load resistor, e.g. the measuring shunt of an evaluation device, requires a minimum supply voltage
[U
Smin
]. Dependent on the connected supply voltage [U
S
], it results in a maximum value for this
resistor [R
Lmax
], where a correct function is still possible.
4.4.2
Elektronik Ausgang – 3-Draht, Spannung 0…1
0
V
A load resistor, e.g. the measuring shunt of an evaluation device, requires at a definitive output
voltage [U
out
] an output current. Due to the limitation of that output current, it results in a minimum
value for this resistor [R
Lmin
], where a correct function is still possible.
