Power supply cable (C) Relay box
*1: Power terminal "G" on Relay box must be grounded (ground resistance: 100 ohm or less).
In case of selecting -A5, power supply cable connects with L(101), N(102) and G(001) in Relay box.
*2: 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.
*4: In case of selecting -A5, purchase the solenoid valve corresponding input power supply and frequency.
See ● Solenoid valve (SV1 to SV4).
