Installation method

1. Parts prepared at site

1

Prepare an electric box.

2

Prepare lock nuts and bushing that match the conduit.

3

Prepare an M-NET transmission line CVVS(2-wire):
1.25mm

2

 or equivalent.

4

DC power supply line (3-conductor): Provide
0.75mm

2

 or greater.

2. Installation method

1

Secure the space shown on the right when installing the electric box.

2

When installing the controller on the electric box, the controller will be shifted by 1mm to the left as shown above.

NOTE

* When installing two controllers horizontally in parallel, secure a clearance of 30mm or more between the products.

When installing vertically with the same clearance, removing of the cover will be difficult.

* When connecting a LAN and RS-232C, a space for the connector and wiring is required. Provide this space between this unit

and the rear of the electric box.

It varies depending on the specifications of the LAN cable and RS-232C cable that is procured, but the LAN connector may
protrude approximately 20mm and the RS-232C connector may protrude approximately 40mm from the bottom of the unit cabinet.
Provide a cable with the smallest possible connector to secure space.
Reference example) Example of installation when a 67mm deep electric box is used with a 30mm thick wall.

3

Connect the M-NET transmission line (centralized control line which is connected to TB7 of the outdoor unit) to M-NET transmis-
sion line terminal A and B. (Non Polarity)
Connect the DC power line from the power supply unit (PAC-SC50KUA) to the DC power supply terminal block of this device.
There is a 12VDC and a GND polarity.

* Type of wire. Use the cables which comply with the following specifications or equivalent.

M-NET transmission line:

CVVS

1.25mm

2

 (PVC-insulated, PVCsheathed shield control cable)

CPEVS

ø1.2mm (PE-insulated, PVC-sheathed shield communication cable)

DC power line: 0.75mm

2

 or greater 3-conductor power line

CAUTION

* Do not connect the AC power line to the M-NET and

POWER (DC12V) terminal blocks of this device. It may
cause a failure.

* Do not connect to the M-NET transmission line of indoor

unit control line which is connected to TB3 of the outdoor
unit.

* The conduit outlet faces only vertically. When leading the

line out from above, seal the port so that water does not
enter along the transmission line and DC power supply
line.

4

Securely seal the line lead-in port with putty to prevent the
entry of dew, water and insects, etc.

* Seal the connecting section of the electric box and conduit with

putty.
