Set LG (shield ground) switch
· For communication lines, use a coaxial cable.
· As coaxial cable is an unbalanced circuit,
ground its shield by turning “ON” the shield
ground switch.
• Make sure to provide a class-3 grounding for the GND terminal of the power supply module.
Without grounding the power supply module, the JW-20CM cannot become conductive with
the ground after turning “ON” the shield ground switch. (See page 7·2.)
• Prior to any electric welding around the JW-20CM, take out the coaxial cable from the JW-
20CM. While the coaxial cable is connected to the JW-20CM, any electric welding nearby the
JW-20CM will cause the welding current to the JW-20CM and may damage part of its circuit
pattern.
