Be sure to shut off the power source of the unit and all
the other unit to connected to the unit before wiring.
Doing so may cause an electric shock or a malfunction.
Use only an earth leakage breaker and fuse of the
specified capacity.
If no earth leakage breaker is installed, it may cause an
electric shock.
Using fuse and wire or copper wire with too large capacity
may cause a malfunction of unit or fire.
Use standard wires in compliance with the current
capacity.
A failure to this may result in an electric leakage, heating or
fire.
This appliance must be earthed.
Make sure to install a protective earth(PE) line. Do not
connect the protective earth line to gas or water pipes,
lightning conductors or telephone grounding lines. Improper
grounding may cause an electric shock.
Wire so that it dose not received any tension.
Tension may caused wire breakage, heating or fire.
Do not touch the switches with wet fingers.

The free topology transmission specification includes two components which must both be met for proper
system operation. The distance from each transceiver to all other transceiver and to the termination
(including the LPI-10 termination, if used) must not exceed maximum node-to-node distance.
If multiple paths exist, e.g., a loop topology, then the longest path should be used for the calculations.
The maximum total wire length is the total amount of wire connected per segment.

5. Confirming Operation
5-1 Pre-operation preparations and settings
(1) Perform the previous operations described in Chapter 3 “ Installation” , Chapter 4 “ System Settings” .
(2) Perform a test operation of indoor units. If being used together with MELANS, perform the installation and electrical
installation for MELANS.
(3) Turn on the power supply for LM-AP. If being used together with MELANS, perform the initialization settings.
(4) The units will be idle until the LM-AP initialization has been completed (LED002 goes out).
❇ This requires approximately 5 to 10 minutes. (If being used together with MELANS, it will be approximately
3 minutes after the completion of the initialization settings.)
(5) Check whether or not LM-AP service LED (LED003 and LED004) have come on.
(6) Refer to the following chapter “6. Troubleshooting” if the LM-AP connection error (LED003) or unit error (LED004) is ON.
(Note 1) Always refer to the previous chapter “4. System settings” before changing the system configuration,
such as the M-NET address.
❇ After confirming the above details, always refer to the following section “5-2. Trial operation procedures” and
make confirmations with trial operations.
❇ Turn all of the switches in the service switch (SW2) [OFF] to confirm the ON/OFF status of the above service LED
(LED002, LED003 and LED004).
5-2 Test-operation procedure
(1) Test-operation of the indoor unit from LM-AP
1. Turn on SW1-9 of LM-AP.
❇ If there is even one indoor unit that is not running, the LM-AP may not correctly recognize the indoor unit.
Refer to the next chapter “Troubleshooting”.
2. Finally turn OFF SW1-9, and verify that all indoor units are stopped.
(2) Test-operation of the indoor unit from LONWORKS®
If there is any tool which corresponds to LONWORKS®, verify that it can be operated from LONWORKS® network according
to the following procedure.
1. Set the LM-AP in the config.
If LM-AP has been already bounded to another model (the service LED is not ON), don't apply any new binding.
2. During the test operation, use “ nv1n Reguest On/Off ” to verify that the indoor unit can be operated.
For details of “ nv1n Reguest On/Off ” , refer to the following.
nv1n Reguest On/Off
network input SNVT_switch nviOnOff_n ;
This input network variable is used to allow On reguest or Off reguest of the indoor unit to be changed via
the network.
When the ventilator(LOSSNAY) interlocks with the inddor unit, it becomes the same operations the indoor uint.
