♦Cautions

•Welding current
This product has no immunity against D.C. magnetic fields, so it is not suitable for use in applications
where welding takes place using D.C. inverter/rectified source. If using in conjunction with a D.C.
welding application, use it at a distance from the conductor, as with ordinary switches.

Rough guide for distance from conductor to prevent malfunction (10,000A: 30cm or more).
