Installation Work (Option) - FG Europe LMTA Series Installation Manual

External input and output
12.1.
12.1.1. 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.
• 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.

12.1.2. External output
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 25 m.
• 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

12.1.3. Connection methods
Wire modifi cation
• Remove insulation from wire attached to wire kit connector.
• Remove insulation from locally purchased cable. Use crimp type insulated butt
connector to join fi eld 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.

NOTES: Be sure to change the DIP SW to the corresponding remote controller.
When a 2-wire remote controller is connected to a "3WIRE" setting, power will
not be supplied.
When a 3-wire remote controller is connected to a "2WIRE" setting, a
communication error will be detected.
