4. Wiring
4.1 Preparation of wiring
You should read and connection method of supporting the use of thermal mass flowmeter
or other unit instrument system and requires careful - before connection;
The external cable recommended two core shielded cable and cable connection and
good sealing;
The explosion-proof products should be selected in accordance with the relevant
standard of BenAn instrument cable and make sure that the cable parameters meet the
explosion-proof instrument system requirements;
Working voltage range of DC18~30V. When the voltage is higher than DC30V, the
instrument will be damaged, and measures should be taken to prevent the supply voltage
from above 30V;
To the 24V DC power supply thermal mass flowmeter shall meet the requirements of
IEC-1010-1 or equivalent standard SELV safety extra low voltage;
Before the connection with the voltmeter to measure the power supply voltage, the
voltage is DC24V;
