Earth leakage
breaker *1, *2
15 A 30 mA
PEA-200, 250, 400, 500
0.1s. or less
Notes:
*1: Connect an earth leakage breaker to the power supply.
*2: Use earth leakage breakers designed exclusively for ground fault protection only in combination with a local switch or a circuit breaker.
*3: The overcurrent protector using a Class-B fuse is shown.
*4: Power supply cords shall not be lighter than polychloroprene sheathed flexible cord. (Design 245 IEC 53 or 227 IEC 53)
*5: Indoor unit/outdoor unit connecting cords shall not be lighter than polychloroprene sheathed flexible cord (Design 245 IEC 57).
*6: A switch with at least 3 mm contact separation in each pole shall be provided by the Air conditioner installation.
*7: The connection wiring between the outdoor and indoor units can be extended up to a maximum of 50 m.
Caution:
Do not use anything other than the correct capacity breaker and fuse. Using
fuse, wire or copper wire with too large capacity may cause a risk of mal-
function or fire.

10.1 Grouping by using LCD remote controller

Combination of indoor/outdoor unit can be controlled up to a maximum of 16 refrig-
erant systems.
[Fig. 10.1.1] (P.6)
A Outdoor unit
C Main remote controller
E Standard (Refrigerant address = 00)
F Refrigerant address = 01
H Refrigerant address = 03
J Refrigerant address = 15
* Set the refrigerant address using the DIP switch of the outdoor unit.
* Refer to the outdoor unit installation manual for setting method of SW1
DIP switch.
1 Wiring from the Remote Control
This wire is connected to TB5 (terminal board for remote controller) of the indoor
unit (non-polar).
2 When a Different Refrigerant System Grouping is Used
Up to 16 refrigerant systems can be controlled as one group using the LCD remote
controller.
Notes:
1. In single refrigerant system, there is no need of wiring 2.
2. LCD remote controller can be installed up to a maximum of 2 units for
one group.

* Set the refrigerant system address of one outdoor unit to 00 for the power supply
to the remote controller.
(The refrigerant system address is set to 00 when shipped from the factory.)
Do not duplicate the refrigerant system address settings within the same system.
