Installation and Wiring
1) Open the mounting hole.
Open two holes for M4 screws with a 139 mm
1 mm
interval for valve ON/OFF control type / a 189 mm
1
mm interval for valve proportional control type.

2) Mount Infilex FC with two M4 screws. Make sure that
Infilex FC is tightly fixed with the screws.

IMPORTANT:
Mounting screw tabs of Infilex FC are 5 mm thick
each. When you reuse the mounting screws for
IFC (Intelligent FCU Controller), you may damage
the mounting wall/panel (behind Infilex FC) since
the screws used for IFC are inserted 15 mm
deeper inside the wall/panel.
3) To mount Infilex FC on a threaded rod (
9 mm) in the
ceiling, use two cable ties. Put a cable tie through two
holes on the bilateral sides of the M4 screw hole on a
screw tab. Instead of cable ties, two fasteners can be
used to mount Infilex FC on the threaded rod. Refer to
Fig. 8 for mounting with cable ties / fasteners.
Infilex FC mounted on the treaded rod may rotate as an
axis. Do not allow the tension on the cables when wiring.

4) Crimp M3.5 terminal lugs on the power cables, and
connect them to the screw terminals. Connect the
modular cables of LS-bus, user I/F, and Pt100 to the
modular jacks (on Infilex FC) until they click. Pull lightly
out the cables to make sure the modular plugs are
completely connected to the modular jacks.
IMPORTANT:
Do not apply 98 N
cm or larger torque for
connecting the screw terminals.
WARNING
To prevent electrical shock, be sure to turn off
the power supply to Infilex FC before connecting
the power cables.
