*1
*1: Power terminal "G" on TB820D must be grounded (ground resistance: 100 ohm or less).
In case of selecting -NN as Relay box for solenoid valve, power supply cable connects with L(101), N(102)
and G(001) in TB820D.
*2: The connection cables are 1 m in length normally.
They are available with /L02, /L03, /L05, /L10 or /L20 depending on the length you need.
*3: When suffix code -U1 is specified, PG400 should be purchased separately.
Neither Ultrasonic oscillator cables nor power cable are supplied with the product. Purchase them separately.
See GS 19C01B05-01EN.
