Ask your dealer or technical representative to install the
unit.
Any deficiency caused by your own installation may result in
an electric shock or fire.

Install in a place which is strong enough to withstand
the weight of the PAC-SC30GRA.
Any lack of strength may cause the PAC-SC30GRA to fall
down, resulting in personal injury.

Firmly connect the wiring using the specified cables.
Carefully check that the cables do not exert any force
on the terminals.
Improper wiring connections may produce heat and possi-
bly a fire.

Never modify or repair the PAC-SC30GRA by yourself.
Any deficiency caused by your modification or repair may
result in an electric shock or fire.
Consult with your dealer about repairs.

Safety Precautions

The following two symbols are used to denote dangers that may be caused by incorrect use and their degree:

WARNING

This symbol denotes what could lead to serious injury or death if you misuse the PAC-SC30GRA.

CAUTION

This symbol denotes what could lead to a personal injury or damage to your property if you misuse the PAC-SC30GRA.

After reading this installation manual, keep it in a place where the final user can see it anytime he or she wants to it.
When someone moves, repairs or uses the PAC-SC30GRA, make sure that this manual is forwarded to the final user.

WARNING

WT02948X01

Ensure that installation work is done correctly follow-
ing this installation manual.
Any deficiency caused by installation may result in an elec-
tric shock or fire.

All electrical work must be performed by a licensed tech-
nician, according to local regulations and the instruc-
tions given in this manual.
Any lack of electric circuit or any deficiency caused by in-
stallation may result in an electric shock or fire.

Do not move and re-install the PAC-SC30GRA yourself.

NOTE: The remote controller cord is supplied on site.

Use a electric cable in accordance with the following specifications.
Electric cable specifications (CVV or CVVS)
With CVVS, be sure to insulate the cable shield so that it does not contact the terminal block.
The 1.25mm

Do not install in any place where acidic or alkaline solu-
tion or special spray are often used.
Doing so may cause an electric shock or malfunction.

Use standard wires in compliance with the current ca-
pacity.
A failure to this may result in an electric leakage, heating or
fire.

Do not touch any PCB (Printed Circuit Board) with your
hands or with tools. Do not allow dust to collect on the
PCB.
Doing so may cause fire or an electric shock.

Do not remove the insulation sheet on the PCB.
Doing so may cause an electric shock.

Do not touch any control button with your wet hands.
Doing so may cause an electric shock or a malfunction.

Do not press any control button using a sharp object.
Doing so may cause an electric shock or a malfunction.

Never contact the power supply with the control wiring
terminals.
Doing so will certainly cause the controller to catch fire.

Do not install in any place exposed to flammable gas
leakage.
Flammable gases accumulated around the body of PAC-
SC30GRA may cause an explosion.

Do not use in any special environment.
Using in any place exposed to oil (including machine oil),
steam and sulfuric gas may deteriorate the performance sig-
nificantly or give damage to the component parts.

Wire so that it does not receive any tension.
Tension may cause wire breakage, heating or fire.

Completely seal the wire lead-in port with putty etc.
Any dew, moisture, insects entering the unit may cause an
electric shock or a malfunction.

Do not wash with water.
Doing so may cause an electric shock or a malfunction.

Do not install in any place at a temperature of more than
40

°

C or less than 0

°

C or exposed to direct sunlight.

Do not install in any steamy place such a bathroom or
kitchen.
Avoid any place where moisture is condensed into dew. Doing
so may cause an electric shock or a malfunction.

PAC-SC34KUA

CAUTION

1. This diagram shows the configuration of transmission wiring, and omits power supply wiring for clarity.
2. Establish one shield ground for M transmission wiring within the system.
3. The number of system controllers which may be supplied with power are found by multiplying the given num-

ber by the appropriate capacity coefficient in the following table (decimal fractions are rounded up).

Capacity coefficient

4. The eight groups are allocated automatically (group remote controller setup address

-200~group remote controller setup address -200+7 is the management group).
Examples: Group 1~8 is the management group when the group remote controller setup address is 201.

Group 9~16 is the management group when the group remote controller setup address is 209.

5. As current consumption is twice that with remote controller when this equipment is connected to indoor or

outdoor transmission wiring, assume two remote controllers for each of these units when calculating connec-
tions.

How To  Install

(1) Choose a location in which to install the group remote controller (switch box) in accordance with

the following requirements:

1

The space as shown in the diagram at right is required whether
the controller is installed on the wall or in the switch box (except
when used with the program timer (PAC-SC32PTA)).

(4) Set the group remote controller address with the rotary switches.

(5) When used in conjunction with the master system controller (centralized controller), set the group

remote controller to “Slave” with the switch as shown in the diagram below.

• The switch is set to “Master” when shipped from the factory.

Group remote controller upper case

(6) Connect this connector on the lower case to the connector CN1 on the upper case.

CAUTION

• Connect firmly as shown below. The system will not operate unless these connections are

made.

• After connecting the wiring, ensure that the upper case does not hang off the cord as shown in

the diagram below at the right. This may result in a break in the cord, and thus cause problems
with operation.

• Always pass the cord through the hook to hold it in place.

CAUTION

• Press the case until it snaps shut.
• A protective sheet has been affixed to the control panel.

Remove it before starting.

CAUTION

Do not turn the screwdriver while it is inserted into the
open slot. Doing so can result in damage to the claws.

To remove the upper case, insert a minus screwdriver
into one of the open slots and move it in the direction of
the arrow as shown in the diagram at right.

(8) Wiring hole for fitting directly onto the wall.

• Cut out the thin-wall portion of the upper case (shaded area) using

a knife or nipper.

• Take out the remote controller cord connected to the terminal block

via this portion.

• When cutting a hole in the wall for the remote con-

troller cord (ie when the remote controller cord exits
from the rear of the remote controller), seal this hole
in the same way.

• When fitting to the switch box, seal the join between

the switch box and the wiring conduit with putty.

(10) Affix a caution label.

A caution label in English is supplied on the back surface of the upper panel. Affix another caution label in the
language of a country where you use the Group remote controller over the English one.

Connecting Optional parts

• When connecting a program timer connect a 5-core cable to connector

CN2 (timer connector) on the upper case (a 5-core cable is supplied with
the program timer).

• Cut out the thin-wall portion to take the cable.
• When fitting directly onto the wall, fit the group remote controller on the left

of the program timer to facilitate wiring. If you anticipate installing more
program timers, leave the appropriate space to the left of the remote con-
troller. See the program timer installation manual for installation details.
