1. SAFETY

Please take a moment to review these safety precautions. They are provided for your protection and to prevent

damage to the controller.

This safety information applies to all operators and service personnal.

After you have read this manual, always observe the procedures described in the explanations and store it with

the installation manual in a location that is easy to find. If the controller is going to be operated by another per-

son, make sure that this manual is given to them.

Symbols and Terms

Specific Precautions

WARNING

CAUTION

Statements identify condition or practices that could result in personal injury or loss of life.

Statements identify condition or practices that could result in damage to the controller or other property.

• Do not install the controller in a place where inflam-

mable gas could leak.

If gas leaks and collects around the controller, it may cause

a fire or explosion.

• Do not wash the controller with water.

It may cause an electric shock or malfunction.

• Do not touch the switch with wet hands.

It may cause an electric shock.

• Do not use the controller for special applications.

This product is designed for use with the MITSUBISHI

ELECTRIC BUILDING AIR CONDITIONING CONTROL

SYSTEM. Do not use the system for other air condition man-

agement operation or applications. It may cause malfunc-

tions.

• Do not apply insecticide or flammable sprays to the

controller.

Do not place flammable spray near the controller and make

sure it does not blow directly on the controller as this may

cause in fire.

• Do not use the controller in special environments.

The performance may be reduce or parts may be damaged

if the controller is used in locations subject to large quanti-

ties of oil (including machine oil), steam, sulfide gas.

• Do not touch the switches with sharp objects.

It may cause an electric shock or malfunction.

• Operate the controller within the specified temperature

range.

Observe the specified temperature range when operating

the controller. If the controller is used outside the specified

temperature range, it may cause serious damage. Be sure to

check the operation temperature range in the operation

manual.

WARNING

• Ask your dealer or technical representative to install.

If incorrect inatallation is done by a customer, it may cause

an electric shock, fire, etc.

• Make sure that the controller is connected to a rated

power supply.

If the controller is not connected to a rated power supply, it

may cause a fire or damage to the controller.

• Never remove the cover during operation.

Touching the charged parts of the controller may cause

severe burns or other personal injury.

• Stop the operation if any malfunction occurs.

If malfunction occurs (burning smell, etc.) stop the operation

and turn off the power supply. Contact your dealer or techni-

cal representative immediately. If the controller continues to

operate after a malfunction occurs, this may cause damage,

electric shock or fire.

• Do not remodel or repair by yourself.

If the controller is redesigned or repair is not correct, it may

cause an electric shock, fire, etc.

Consult your dealer if repair is necessary.

• Stop the operation immediately and notify the your deal-

er if an error code is displayed or malfunction occurs.

Fire or damage may be caused if the controller is operated

in this condition .

CAUTION

• Do not move and re-install the controller by yourself.

If installation is incorrect, it may cause an electric shock,

fire,etc. Ask your dealer or technical representative.

• Contact your dealer if the controller will not be used any

more or will be scrapped.

• Securely install in a place which can withstand the

weight of the controller.

If it is not enough, the controller may fall and cause an

injury.

In addition, room temperature can be displayed at the unit of each group upon request.

Access to specific control functions, such as ON/OFF operation, mode selection ,temperature setting and filter

sign reset operation can be prohibited for the local remote controls collectively or per group.

Operation setting can be performs collectively or per group.

In addition, it is possible to set ON time only (prohibition time only) and OFF time only (permission time only).

Daily operation patterns and weekly schedules for one group can easily be copied to the other groups.

The central controller is supplied power from the PAC-SC50KUA Power Supply Unit via the M-NET transmission line and

DC power line. The DC power between the PAC-SC50KUA Power Supply Unit and the central controller should be 10m

or less. The central controller allows to be connected to M-NET transmission line at any position. (M-NET transmission
