●
Avoid installing this instrument near an electrical unit (high frequency furnace or electric welder)
that generates much electrical noise. If using the instrument near such a noise generating unit is
unavoidable, use a different power line to avoid noise.
●
Mount a noise suppressor such as varister or spark killer
as shown at right figure to the noise generating unit when
noise is generated from relays or solenoid valves.
Mount the suppressor near the noise generating source, or
it will have no effect.

(1) Power supply (standard terminal 1 to 2)
Connect the given power supply to the power terminal, and connect the ground wire to the ground-
ing terminal (standard terminal 3). Be sure to perform protective earth connection. Use solderless
terminals (for M3.5) for connection to the terminals (power and earth).
