When connecting the power cable, pay attention to select the appropriate voltage level wiring. For
different voltage levels, select 220V AC or 24V DC wiring to avoid power wiring faults.
When wiring, select the corresponding power terminal to connect to the power line according to the
product specifications, and then connect to the signal line according to the required output form. See
Table 3 for the specific meaning of the integrated electromagnetic flowmeter wiring terminals.
