Warning

This symbol refers to a hazard or unsafe procedure or practice that can result in severe personal injury or

death.

Caution

This symbol refers to a hazard or unsafe procedure or practice that can result in personal injury or product or

property damage.

* 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.

Warning

●

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.

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

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.
