INSTALLATION INSTRUCTIONS
Communication Adaptor
Model No. CZ-CFUNC1U
For your safety
Read the following instructions carefully, and carry out secure installation and electrical work.
■
The precautions given in this manual consist of specifi c “Warnings” and “Cautions”. They provide important safety-related information. Be
■
sure to strictly observe all safety procedures. The labels and their meanings are as described below.
Warning
Caution
* After installation is completed, perform a test run to check for operating trouble. Explain operating procedures to the customer following the
central control device Operating Instructions and then request the customer to store this Instructions for the Electrical Installer together with
the central control device Operating Instructions.
Be sure to arrange installation by the dealer where the system was purchased or by a professional installer. Electric shock or fi re may result
●
if an inexperienced person performs any installation or wiring procedures incorrectly.
Be sure that this unit is securely installed in accordance with this Instructions for the Electrical Installer. Electric shock or fi re may result if
●
any installation or wiring procedures are incorrectly performed.
Only a qualifi ed electrician should attempt to connect this system, in accordance with the instructions in this manual. Insuffi cient electrical
●
circuit capacity or incorrect installation may cause electric shock and fi re.
Use the specifi ed cables for the electrical connections, and connect the cables securely. Run and fasten the cables securely so that
●
external forces or pressure placed on the cables will not be transmitted to the connection terminals. Overheating or fi re may result if
connections or attachments are not secure.
Depending on the installation conditions and location, an earth leakage breaker may be required. If an earth-leakage breaker is not
●
installed, there is a danger of electric shock or fi re.
This symbol refers to a hazard or unsafe procedure or practice that can result in severe personal injury or
death.
This symbol refers to a hazard or unsafe procedure or practice that can result in personal injury or product or
property damage.
Warning
Caution
Ground yourself to discharge static electricity before performing any wiring.

Note:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: To assure continued compliance, follow the attached installation instructions. Any changes or modifi cations not expressly
approved by the party responsible for compliance could void the user’s authority to operate this equipment.
Installing
1
Note
Do not run the indoor/outdoor communication lines, input/
●
output lines, and power cables through the same conduit, or
twist those cables together, or place the cables near one
another. It can cause malfunction.
Install the main unit away from any sources of electrical
●
noise.
Avoid installing in any locations where the unit may come
●
into contact with water, or in any extremely humid locations.
Avoid installing in any location that is subject to excessive
●
vibration or physical impacts.
(1) After determining the attachment position, secure the
installation hardware as shown in the dimensions diagram. If
the included screws will not work for the installation, prepare
appropriate screws (such as metric ones) for use at the site.
(2) Attach the main unit and fasten the installation hardware as
illustrated.
(3) If the installation hardware is loose or appears like it will fall
out, remove the upper case on the unit and secure with
screws in the failsafe screw holes.

(1) Connecting the power supply
The unit can use AC power sources between 100 and 240 V.
Connect the power supply to terminals 2 (N) and 3 (L) on the power terminal strip CN1. (Connect the AC neutral end to N.)
Connect the ground line securely.

(2) Connecting the communication line
For the Communication Adaptor control wires, use only two-conductor shielded wire with a cross-section between AWG#20 and AWG#14
●
(MVVS or CPEVS).
Be sure to ground only one end of the shielding.
●
The overall length of each line should be 3280 ft. or less.
●
Do not run the communication line through the same conduit as the power supply, use the same cable as the power supply, or run close to
●
the power supply line (maintain at least 11-13/16 in. separation).
Do not run the LINK1 and LINK2 signal lines through the same conduit, use the same cable for wiring, or run them close together.
●
Use different communication and power cables so they can be differentiated visually.

terminals have polarity. Connect so
the positive and negative elements
are correct.
When connecting, be sure to use
crossover wiring, not a branching
confi guration.
(Some items are duplicated in other sections.)
(1) The overall length should be 3280 ft. or less.
(2) The communication wire has polarity. Connect so the positive and negative elements are
correct.
(3) Use only shielded wire. Be sure to ground only one end of the shielding.

(6) Do not hook more than 16 units up
to the Communication Adaptor. The
system you are using (such as an
Intelligent Controller) may have
further restrictions. Consult the
Installation Instructions for your
system.
* The Intelligent Controller has a
maximum restriction of seven
units.
(7) Make sure that high voltage AC
lines are not connected to the
Communication Adaptor control
wire or the inter-unit control wiring
terminals.
* If high voltage AC is accidentally
applied to the inter-unit control
wiring terminals, a fuse will blow to
protect the controller board.
If this happens, disconnect the AC
line, and connect the U2 terminal
wire of the inter-unit control wiring
to the spare terminal. (Do not
change the U1 terminal wire.)
Spare terminals are located right
next to U2.
