Surge absorbing devices（diodes, varistors, etc.）are necessary if inductive loads such as relays or solenoids are connected to the same circuit as the PG- 35L.
If using a DC power supply unit such as a switching power supply, the FG terminal should be earthed. Do not wire in parallel to high tension cables or power lines, or use cable ducts which contain high tension cables or power lines.
Be careful not to crimp any wires during handling, or put any pressure on the display area of the main body while assembling piping.
