8 Wiring Instruction 

8.1 Preparations 

8.1.1 Please note the following safety precautions before use:

 

The instrument wiring is only permitted when it is powered OFF.   
If overvoltage occurs to the wire, please install overvoltage protection device to protect the 
instrument. 

 

8.1.2 Connecting cable

 

The instrument can be connected with the general 2-core wire without the shielding layer 
available on the market.   
If electromagnetic coupling phenomenon occurs to the installation and wiring environment, and 
the value exceeds the inspection value of EN61326-1 Standards applicable to the industrial 
field, the cable with shielding cable should be used. For the instrument with housing and cable 
screw thread connector, please use the cable with circular cross-section. Please check the 
external diameter of the cable applicable to the cable screw thread connector, so as to ensure 
the sealing on the cable screw thread connector (IP protection method). Please use the cable 
screw thread connector matching with the cable diameter.   
 

Note!   

When wiring, please follow the requirements of DIN EN 61140 VDE 0140-1(Protection against 
electric shock - Common aspects for installation and equipment), to guarantee the safety 
isolation between the power circuit and the grid circuit.   
When the cable with shielding isolated mesh is used, it is recommended setting up the 
shielding isolated mesh on both sides of earth potential. In the sensor, the shielding isolated 
mesh must be directly connected with the internal grounding terminal. The external grounding 
terminal on the housing must be connected with the low impedance of the earth potential. For 
explosion-proof equipment, it should perform grounding based on the requirements on the 
license.   
For the electroplating and KKS equipment (cathodic anticorrosion protection), the great 

potential difference should be considered. When the shielding isolated mesh is grounded on 

both sides, it may cause the current of the shielding isolated mesh to exceed the permitted 

scope.   

 

 

8.1.3 Power supply

 

The product is connected with a 2-core wire to supply power and send current signal   
Working voltage (Vs):   
With display adjustment module: 16~30VDC 
Load impedance:(Vs-Vmin)/0.022A 
For example: When supplying 24VDC for the instrument with display adjustment module: 
(24-16)/0.022 = 363
