2. Connecting the power supply cable and
transmission cable
Pass the power cable through the bush* and connect to the TM1
terminal block using the round terminals. Connect the ground wire
to the ground terminal and secure tightening the bush. (*: for PG

CAUTION
• Always separate the power supply cable and transmission cable by
2" (5 cm) or more to prevent malfunctioning of the unit.
• If the length of the stripped power cables wires is too long, the
conductors may touch and short out.
• Power supply cable size : AWG 14 (ø 1.6) or more.
(1) Tighten the ground wire and 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.

The following system configuration can be
created. Connect the necessary parts.
1 When connecting with remote controller (PZ-60DR-E, PZ-41SLB-E).
2 When interlocked with indoor unit of air conditioner or other
external device including other manufactures.
3 When interlocking with a pulse output device.
4 When operating multiple Lossnay units.
5 When take malfunction monitor output, or take Bypass operation
monitor output.
6 When connect to an Electrically operated damper, or take
operation monitor output.
7
When switching High / Low / Extra-Low speed externally (when CO
sensor or other device is connected).
8 When switching Bypass externally.
9 When using the remote/local switching and the ON/OFF input (level signal)
10 When connecting to the City Multi, Lossnay remote controller (PZ-52SF-E)
or Mitsubishi Electric Air-Conditioner Network System (MELANS).
CAUTION
• When connecting external devices (electrically operated damper,
lamp, monitoring unit, etc.) using output signals of the Lossnay unit,
make sure to install safety equipment for the external devices.
(It could cause fire, damage, etc. without safety equipment.)
When connecting with remote controller (PZ-60DR-E, PZ-

41SLB-E)
* When controlling Lossnay units with the central control, connect
wires according to 10 .
Securely connect the transmission cable (PVC insulated PVC jacketed and
either between AWG 22 (ø 0.65) and AWG 16 (ø 1.2), or between AWG
22 (0.3 mm 2 ) and AWG 16 (1.25 mm
controller to 1 and 2 of the input terminal block (TM4). (No polarity)
• If there are two remote controllers, connect them in the same way.
Note
• Don't tighten screws of terminal block with a torque larger than 0.5
Nm. It could damage the PCB.
• Number of transmission wires which can be connected to single
input terminal is up to 4 wires for AWG 22 (ø 0.65) PVC wire or AWG
2
22 (0.3 mm ) stranded wire. It is up to 2 wires for any other wires.
• PZ-41SLB-E cannot be used when MELANS centralized control of
the Lossnay is used.
• PZ-60DR-E and PZ-41SLB-E cannot be installed simultaneously.

CAUTION
• The connection may vary according to the output signal type of the
external unit.
• Don't tighten screws of terminal block with a torque larger than 0.5
Nm. It could damage the PCB.
