INFORMATION
Multi units are standard combinations.
15.2 Safety device requirements
The power supply must be protected with the required safety
devices, i.e. a main switch, a slow blow fuse on each phase and an
earth leakage protector in accordance with the applicable legislation.
For standard combinations
Selection and sizing of the wiring should be done in accordance with
the applicable legislation based on the information mentioned in the
table below.

RXYQQ20 39.0A 50A
For all models:
▪ Phase and frequency: 3N~50Hz
▪ Voltage: 380~415V
▪ Transmission line section: 0.75~1.25 mm

, maximum length is
1000 m. If the total transmission wiring exceeds these limits, it
may result in communication error.
For non-standard combinations
Calculate the recommended fuse capacity.
Formula Calculate, by adding the minimum circuit amps of each
used unit (according to the table above), multiply the
result by 1.1 and select the next higher recommended
fuse capacity.
Example Combining the RXYQQ30 by using the RXYQQ18, and
RXYQQ12.
▪ Minimum circuit ampacity of the RXYQQ18 =35.0A
▪ Minimum circuit ampacity of the RXYQQ12=24.0A
Accordingly, the minimum circuit ampacity of the
RXYQQ30=35.0+24.0=59.0A
Multiply the above result by 1.1: (59.0A×1.1)=64.1A,
so the recommended fuse capacity would be 80A.
NOTICE
When using residual current operated circuit breakers, be
sure to use a high-speed type 300 mA rated residual
operating current.
15.3 Field wiring: Overview
Field wiring consists of:
▪ power supply (including earth),
▪ DIII transmission wiring between communication box and outdoor
unit,
▪ RS‑485 transmission wiring between communication box and
monitoring system.
