Internal shield should be connected through the multi-stranded drain wire.
It is recommended to use "RVVP" shield cables as electrical connection cables. The power cord
should be connected from the hole on one side and the signal cable should come out from the
hole on the other side.
Special shield cable connecting the transducer and the transmitter should be placed far away
from strong electromagnetic to avoid interference; DO NOT place it with HV cables. Special
cables should be minimum with no coiling to eliminate the distributed inductance.

Connecting electrical cables
Warning!
Signal cables and power cables must be connected while the power is off.
Warning!
As specified, the meter must be connected to the protective ground terminal to protect
operators from electric shock.
Warning!
As for the meters to be used in hazardous areas, please pay attention to the safety and technical
prompts as specified in the professional explosion-proof instructions.
Caution!
Please strictly obey the local occupational health and safety regulations. Only trained personnel
are allowed to operate on electrical equipment.
Warning!
Voltage difference is not allowed between the measuring transducer and the housing or
protective ground cable of the electronic system.
The measuring transducer must be well grounded according to related standard DESIGN CODE
OF INSTRUMENT GROUNDING (HT/T 20513-2014).
The ground conductor shall not transmit any disturbance voltage.
The ground conductor is not allowed to connect other electrical equipment.
