Wiring
Wiring to the power supply terminals
Crimp the M3 terminal lugs to the wire ends, and connect
them to the M3 screw terminals.
Wiring to I/O modules and expansion bus terminals
Since screwless push-in terminals are adopted for the I/O
modules and the expansion bus terminals, the procedure for
connection is specified as follows.
1) Strip the wire sheath 8 mm. (The gauge for the strip
length is located at the front lower part of Infilex BC I/O
control unit. If the stripped part is longer than 8 mm, the
conductor will be exposed, causing electrical shock or
short circuit between adjacent terminals. If it is shorter,
the conductor may not contact the connector.)
2) Make sure that no wire fiber is protruded from the
conductor (stripped wire).
3) Press the clamp release button on the terminals deeply
enough to insert the wire using a slotted screwdriver.
(Maximum button-pressing force is 14 N.)
4) Release the button, and gently pull out the wire
horizontally to make sure that it is tightly fastened. (If you
pull out the wire diagonally, it may be disconnected.)
Make sure that no wire fiber is protruded from the
conductor (stripped conductor).
Positions for connected wires
Neatly place the wires, using cable ties or the like, connected
to Infilex BC I/O control unit so as not to hide LED, Data
Setter connector,

mark, S1 switch, battery holder, or
indication tag, as shown in Fig. 8.
Make sure there is no slack in the wires from the cable ducts
to Infilex BC I/O control unit.

Tube marker
Since Infilex BC I/O control unit adopts a screwless push-in
terminals, wires are connected without crimp terminals.
Therefore, if normal tube markers are used, they may come
off when the wires are disconnected. To prevent this, use the
following Flat Tube Marker. It is held on a wire by friction and
thus does not come off easily.

Protective sheet
After connecting the wires, be sure to peel off the protective
sheet before turning on the power.
1) Adhesive is applied to the sheet approximately 20 mm
from the front edge. Peel off this area.
2) Tear off the sheet along the perforations.
