[1] Fixing of the cable
In order not to put any force on the cable and the
JW-20CM, fasten the cable to an line nearby input
of a control panel or a “T” branch point to the JW-
20CM using saddles etc.
[2] Extra length of cable
Provide an extra length of the cable of 2 to 3 m
inside a control panel for easier processing of the
cable end and easier wiring when changing module
positions.
[3] Connection to the JW-20CM
The connector to the JW-20CM should be turned
right to secure locking, not merely inserted.
[4] Insulation cover
When the connector touches with a high voltage
section or external enclosures, communication
errors may occur. Make sure to install an insulation
cover.
