Mitsubishi Electric Lossnay LGH-F300RX3-E Installation Instructions Manual page 8

Installation method (continued)
The following system configuration can be created. Connect the
necessary parts.
1. When connecting with remote controller (PZ-41SLB-E).
2. When interlocking with air conditioner or other external device.
3. When interlocking with a pulse output device.
4. When operating multiple Lossnay units.
5. When connecting to CO sensor when switching the high-low switch

externally.
6. When connecting to City Multi, Lossnay remote controller (PZ-52SF-
E) or Mitsubishi Electric Air-Conditioner Network System (MELANS).
1. When connecting to remote controller (PZ-
41SLB-E)
* The PZ-41SLB-E cannot be used when centralized control of
the Lossnay is used. Then follow the procedure for connecting
the wire shown in 6. and use the Lossnay remote controller (PZ-
52SF-E).
Securely connect the transmission cable (PVC insulated PVC jack-
eted and either between φ 1/32" and φ 3/64", or between AWG22
and AWG17 in cross section) from the remote controller to 5 and 6
of the input terminal block (TM2). (No polarity)
• If there are two remote controllers, connect them in the same
way.
Note
Up to four AWG22 stranded wires or φ 3/64" PVC wires can
•
be connected to one input terminal.
• For other types of wire up to two can be connected.

other external device
(1) Connect the output signal cable from the external device to the
input terminal block (TM2) of the external controller.
• LGH-F1200RX -E are conected to the lower circuit board. (Main

CAUTION
• The connection may vary according to the output signal type
of the external unit.
(2) Confirm that the pulse input switch (SW2-2) is set to "OFF".
(Set to "OFF" at time of shipment.)

(A control or K control) unit is not possible.
Connect the interlocking cable connector side to CN2L on the circuit
board for the indoor Mr. Slim unit and connect the lead wire side to
the 1 and 2 of the input terminal block (TM2) for the Lossnay ex-
ternal controller input. (No polarity)
• Always separate the power supply cable and the Slim-Lossnay
connection cable for the Lossnay by 5 cm or more to prevent
malfunctioning of the unit.
• The Slim-Lossnay connection cable is 0.25 m long. When wiring,
extend it as far as necessary.

External controller input (TM2)
Note
• The Lossnay remote controller (PZ-41SLB-E) cannot be used
with this system.
• The ventilation mode is "automatic ventilation".
• The Slim-Lossnay connection cable may be extended to a
maximum length of 1640 ft. (Extension cable specifications
are as detailed below).
Ensure that all connections are secure and that the
appropriate insulation is provided.
Extension cable sheathed PVC cable or cable-AWG20 to

the remote output retrieval component (sold separately) to 1
and 2 on the external control input terminal block (TM2). (No
polarity)
(Follow the operation manual for the external equipment.)
When the external device has an uncharged a-contact signal
• Connect the operating signal (wire) from the external device via
the remote output retrieval component (sold separately) to 1
and 3 on the external control input terminal block (TM2).
CAUTION
• If an optocoupler or any other type of polar coupler is used at
the uncharged a-contact, connect the positive side to 3 3 3 3 3 and
the negative side to 1 1 1 1 1 .
