5) Connect the cables to the quick-fit screwless (clamp)
terminal blocks as follows:
1. Insert a slotted screwdriver into a smaller square hole
(for clamp release) on the terminal blocks located on the
upper and lower side of the front surface.
2. Tilt the screwdriver while pushing it into the hole. (Make
sure the direction to tilt, as shown in Fig. 9.)
When the screwdriver is proceeded to the deep end,
the clamp is completely released.
3. Insert a bare wire (5-6 mm long) into a larger square
hole.
4. Pull out the screwdriver with the bare wire inserted.
Figure 9. Connecting a wire to a quick-fit screwless terminal.
Note:
Regarding wire connection of FCU ON/OFF output, control valve
output, and other inputs, refer to
Wiring for FCU ON/OFF
output, control valve output, and other inputs
section.
6) Bind the cables with cable ties. If an unbound cable is
strongly pulled, Infilex FC may get damaged. Be sure to
bind the modular cables separately from power cables.
Figure 10. Correct and incorrect cable binding.
IMPORTANT:
Do not position any connected cable on the front
surface of Infilex FC, as shown in Fig. 10.
Precautions for Installation
For Infilex FC installation, tightly fix with the screws.
Leave clearance as shown in Figs. 11 and 12. Vertically
mount the Infilex FC (lengthwise). Be sure to mount it in
a location where parts identification indication on the
front surface can be checked.

Figure 12. Clearances for maintenance (mm): side view
To replace a currently installed IFC (Intelligent Fan Coil Unit
Controller) or Microstat
with Infilex FC, a screwdriver with
long grip may not be usable. In such a case, a screwdriver
with short grip or wiring before the installation is required.
1. Insert.
2. Tilt.
3. Insert.
4. Pull out.
Releasing the clamp:
When pushing the screwdriver, tilt
it along the curving surface inside
the square hole.
