supply cable?
3
Are multiple transmission or signal cables wired to the same power
cable duct?
4
Are multiple transmission cables wired with multi core cables?
5

7
Is the wiring length of the transmission cable within the regulations?
Basic system (PZ-60DR-E, PZ-41SLB-E): Total extension within 500
m
M-NET control: Maximum extension within 200 m, total extension
within 500 m
Action
Use speci
fi
ed cables.
Wire the transmission cable at
least 5 cm away from the power
supply cable.
Wire the transmission cables
away from the signal cables.
Using suitable cables, wire the
transmission cables so that they
are separated from one another.
Connect them securely.
Wire the cables within the regula-
tions. (See the technical manual
for details about the regulations.)
Transmission cables (Table 1-1-2)
Check the following checkpoints when connecting with the remote controller, M-NET controller, or City Multi indoor units.
Is the Main/Sub selection switch (SW1) on the Lossnay circuit board
set correctly?
When using one Lossnay unit: Set the unit to “Main”.
When using multiple Lossnay units: Set the
fi
rst unit to “Main” and
the second and following units
to “Sub”.
Set the switches correctly.
9
When using M-NET
Is the address setting on the Lossnay circuit board (SA1, SA2) set to
the correct number?
Make the setting so that the ad-
dress does not duplicate that of
other devices within M-NET control.
10
When PZ-60DR-E is not used, are the function selection switches
(SW2, SW5) on the Lossnay circuit board set correctly?
Set the switches correctly to cor-
respond with the application.
(Refer to page 25 and 26)
11
When PZ-60DR-E is used, is the function selection set correctly?
Set it correctly to correspond with
the application.
(Refer to page 27 to 29)
