2FG
Using a drain wire, connect CA50 (05) to the FG terminal of the connection panel.
Connect the FG terminal of the connection panel to the frame ground by using a twisted–pair
cable that is 100 to 300 mm long with a cross–sectional area of at least 2 mm
2
.
3 The external diameter of the cable used with connector CA50 is 8.5 mm. If the external
diameter of the cable is less than 8.5 mm, increase the diameter to 8.5 mm by using
heat–shrinkable tube or taping at the connector joint to ensure a dustproof connection.
