Connect the Slim-Lossnay connection cable connector side to
CN2L on the circuit board for the Mr. Slim indoor unit, then connect
the lead wire side to the 1 and 2 of the input terminal block (TM2)
for the Lossnay external controller input. (No polarity)
• Always separate the power supply cable and the Slim-Lossnay
connection cable by 5 cm or more to prevent the unit from
malfunctioning.
• The Slim-Lossnay connection cable is 100 mm long. When
wiring, extend it as far as necessary.

• Only one Lossnay and one Mr. Slim unit can be interlocked.
Multiple units interlock is not possible.
• Lossnay can not be connected M-NET in this case.
[SW2-2] setting vary depending on the types of output signal of
external device.
When the external device has a charged operating signal
of 12 VDC or 24 VDC
• If the input is pulse signal, move the pulse input switch [SW2-2]
to the ON position. (Refer to function settings
• When level signal is selected, the signal width has to be more
than 10 seconds for ON and OFF .
• When pulse signal is selected, a pulse width has to be at least
200 m sec. to turn Lossnay ON, and 10 sec. interval is necessary
to next output.
• The wiring should be as shown by the following picture.

When operating multiple Lossnay units
In the case that all Lossnay units are the same LGH-RVS-E series,
up to 15 multiple units can be operated at the same time.
1) Connect the Lossnay unit from Unit 1 to Unit 2, and from Unit 2 to
Unit 3 and so on up to a maximum of 15 units using a transmission
cable.
Wire type: two-core sheathed cable
Wire diameter: 0.3 mm
