Wiring of connector with terminal block :
The wire size that can be connected on this terminal
block is AWG26 to 20. Remove 8mm of outer sheath, and
while pressing
Ⓐ
in the terminal hole with a flat-blade
screwdriver, insert it until the wire is placed, and then
remove the screwdriver.
Cable :
For the output cable, use a cable with a shield structure equivalent to
AWG26 to 20 as shown in the figure below. Fix the shielded wire to the
expansion unit fixing screw on the LY71 side.
Input connector
(set number, latch input)
Shielded wire processing :
Connect the shielded wire on the expansion unit side to either of the
two screws that secure the expansion unit. Of course, the LY71 body
must be firmly grounded. If the connector case used on the device side
is of the type that contacts the FG, connect the shielded wire to the
connector case. If not, wire the shield with a lead wire so that it drops
on the FG on the device side.
