CAUTION
*1: When performing the Insulation Resistance Test or the
Withstand Voltage Test, please obey the following
caution.
• Following the relevant test, wait for more than 10
seconds after the power supply has been turned off
before removing the cover.
• Remove all wires from terminals before testing.
• When the power terminal has a lighting protector
(optional code A), remove the short bar at the ground
terminal.
• After testing, be sure to discharge by using a resistance
and return all wires and the short bar to its correct
position.
• Screws must be tightened to a torque of 1.18 N-m or
more.
• After closing the cover, the power supply can be
restored.
Safety Requirement Standards:

Note: Fluids with large flow noise (pure water, fluid with low
conductivity and low viscosity such as alcohol) cause
the output fluctuation. Be careful that it affects the
flow rate measurement. It is recommended to use the
CA capacitance magnetic flowmeter.
