Cable Wiring Procedure In Control Panel - Sharp JW-21MN User Manual

7-3 Cable wiring procedure in control panel

(1) Fixing of the cable
In order not to put any force on the cable and the
JW-21MN, fasten the cable to an line nearby input of
a control panel or a "T" branch point to the JW-
21MN 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-21MN
The connector to the JW-21MN 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.
(5) Grounding of power supply module (JW-22PU/31PU)
Make sure to use a class-3 grounding to connect the GND terminal of the power supply module.
- If the power supply module is not grounded, the JW-21MN cannot conduct with the ground after
turning "ON" the shield ground switch.
