For all models:
▪ Phase and frequency: 3N~ 50 Hz
▪ Voltage: 380~415 V
▪ Transmission line section: 0.75~1.25 mm
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 RXYLQ18 by using the RXMLQ8 and the RXYLQ10.
▪ Minimum circuit ampacity of the RXMLQ8=16.1 A
▪ Minimum circuit ampacity of the RXYLQ10=22.0 A
Accordingly, the minimum circuit ampacity of the RXYLQ18=16.1 A
+22.0 A=38.1 A
Multiply the above result by 1.1: (38.1 A×1.1)= 41,91 A, so the
recommended fuse capacity would be 45 A.
