Electrical Wiring (1)
Introduction
Connecting posi-
tions for the elec-
tromagnetic
flowmeter main
body
Figure 2-5 (below) shows the terminal block of the electromagnetic
flowmeter main body.
• During wiring, turn OFF the power supply before opening the cover
in order to prevent the danger of electric shock.
• DO NOT perform wiring work while the power is ON, as it may
result in electric shock.
Warning
Notes :
• Perform wiring according to the directions in order to prevent
equipment damage.
• Be sure to check the power line wiring positions carefully, as a
high-voltage power flow is used.
