Optional Kit Installation - Fujitsu ASU30RLE Installation Manual

10. OPTIONAL KIT INSTALLATION

This air conditioner can be connected with the following optional kits. To install these op-
tional kits, the optional PCB kit is necessary.
• External input and output PCB.
Option type
UTY-XCSXZ1 (External input and output PCB)
• Before installing, be sure to disconnect all power supply.
• Do not touch the heat exchanger.
• When installing or removing parts of the air conditioner, be sure that the wire is not
caught by any parts or pulled hard. It may result in damage or malfunction of the air
conditioner.
External input and output
10.1.
10.1.1. External input
• Indoor unit functions such as Operation/Stop or Forced stop can be done by using
indoor unit terminals.
• "Operation/Stop" mode or "Forced stop" mode can be selected with function setting of
indoor unit.
• A twisted pair cable (22 AWG) should be used. Maximum length of cable is 150 m (492 ft.).
• Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed.
• The wire connection should be separate from the power cable line.
● Dry contact terminal
When a power supply is unnecessary at the input device you want to connect, use the Dry
contact terminal.

OFF
● When function setting is "Operation/Stop" mode 1.
Input signal
OFF → ON Operation
ON → OFF Stop
● When function setting is "Forced stop" mode.
Input signal
OFF → ON Forced stop
ON → OFF Normal
* When the forced stop is triggered, indoor unit stops and Operation/Stop operation by a
remote controller is restricted.
● When function setting is "Operation/Stop" mode 2.

OFF → ON Operation
ON → OFF Stop (R.C. disabled)
10.1.2. External output
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 25 m (82 ft.).
• Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed.
• Output voltage: Hi DC12V±2V, Lo 0V.
• Permissible current: 50mA

10.1.3. Connection methods
Wire modification
• Remove insulation from wire attached to wire kit connector.
• Remove insulation from locally purchased cable. Use crimp type insulated butt
connector to join field cable and wire kit wire.
• Connect the wire with connecting wire with solder.
IMPORTANT: Be sure to insulate the connection between the wires.
Locally purchased
Solder and insulate the connected parts.
• Connecting wires to the terminals.
Use ring terminals with insulating sleeves to connect to the terminal block.
• Connection terminals and wiring arrangement
In following figure, all the possible connections are done for description.
In actual installation, connections will differ according to each installation requirements.
