CAUTION
• Always separate the power supply cable and transmission
cable by 5 cm or more to prevent malfunctioning of the unit.
• Take power supply cable and transmission cable into control
box by another hole of the side plate.
• If the stripped length of the power supply cable is too long, the
conductors may touch and short out.
• Adequate power supply cable size is 1.0 mm
(1) Tighten the transmission cables to the terminal block.
(2) Secure the transmission cables using the cord clips.
Upon completion of the wiring connections, replace the control box
cover.
Note
• When using optional signal output terminal (PZ-N4GS-E),
please follow the install manual of it for the electrical
installation as well.

2 When interlocked with indoor unit of air conditioner or other
external device including other manufactures
3 When operating multiple Lossnay units
4 Signal output from Lossnay unit
5 When switching fan speed externally (when a sensor or other
device is connected)
6 When switching By-pass externally
7 To change fan speed by 0 - 10 VDC input
8 When using the remote/local switching and the ON/OFF input
(level signal)
9 When connecting to the City Multi or Mitsubishi Electric Air-
Conditioner Network System (MELANS)

When connecting with remote controller (PZ-62DR-E)
* When controlling Lossnay units with MELANS, connect wires
according to 9 .
Securely connect the transmission cable from the remote controller to
1 and 2 of the input terminal block (TM4). (No polarity)
Wire type: two-core sheathed cable
Wire diameter: 0.3 mm
• If there are two remote controllers, connect them in the same way.
• Keep the overall length of the transmission cable between Lossnay
and the remote controller within 200 m.
Note
• Do not tighten screws of terminal block with a torque larger
than 0.5 N ・ m. It could damage the circuit board.
• Take care not to connect the power supply cable or M-NET
transmission cable.
• When connecting multiple cables to the terminal, use round
terminal.
• Solid wire (single-stranded wire) cannot be connected.
