Safety Precautions
∗ The following is intended for the installer responsible for
installation and test operations of the LonWorks Interface,
and should be carefully read before beginning.
∗ The precautions given in this manual consist of specifi c
"Warnings" and "Cautions." They provide important
safety-related information and are important for your safety,
the safety of others, and trouble-free operation of the

※
After installation is completed, perform a test run to check
for operating trouble. As you do, use the central control
device Operating Instructions and explain operating
procedures to the customer. Then request that the customer
store this manual together with the central control device
Operating Instructions.
• Be sure to arrange installation from the dealer where the
system was purchased or using a professional installer.
Electric shock or fi re may result if an inexperienced
person performs any installation or wiring procedures
incorrectly.
• Please install and ensure construction according to Installation
Instructions of LonWorks Interface.
• Only a qualifi ed electrician should attempt to connect this
system, in accordance with the instructions in this manual.
If the electrical circuit capacity is insuffi cient a danger of
electric shock and fi re may be present.
• Use the specifi ed cables (type and wiring diameter) 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.

Installation Method
• The screws used to install the main unit must be provided by
the installer.
• Install the LonWorks Interface away from any sources of
electrical noise.
Wiring Specifi cations
• For the inter-unit control wiring use twin-core AWG#20 –
AWG#14 cables.
• For the LonWorks communication line cables, use twisted-
pair cables with a wire diameter of 0.51 mm(AWG#24) or
larger as recommended by Echelon Corp.

• Do not use the same cable for the inter-unit control wiring, the
LonWorks communication lines, and the power cable. Do not
run them through the same conduit or place the cables near
one another.
• Connect the cables so that there is no miswiring.
(Miswiring can cause malfunction.)
LonWorks Interface Structure
• This interface contains 4 LonWorks communication boards (nodes).
• Up to 4 indoor unit groups (maximum 32 units) can be
