For all models:
▪ Phase and frequency: 3N~ 50 Hz
▪ Voltage: 380~415 V
▪ 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 RXYQ30 by using the RXYQ8, RXYQ10, and RXYQ12.
▪ Minimum circuit ampacity of the RXYQ8=16.1 A
▪ Minimum circuit ampacity of the RXYQ10=22.0 A
▪ Minimum circuit ampacity of the RXYQ12=24.0 A
Accordingly, the minimum circuit ampacity of the
RXYQ30=16.1+22.0+24.0=62.1 A
Multiply the above result by 1.1: (62.1 A×1.1)=68.3 A, so the
recommended fuse capacity would be
80 A .
NOTICE
When using residual current operated circuit breakers, be sure to use a high-speed
type 300 mA rated residual operating current.
