System Design and Installation
H Leakage Current and Leakage Breakers
Use a surge-resistant leakage breaker designed for Inverters that will not operate for high-frequency
currents. The detection current of a leakage breaker is set to approximately 60% of the normal rated
current. You should thus allow a leeway of approximately two times the rated current.
Leakage current will also flow to the input noise filter, switch mode power supply, and other devices. Be
sure to allow for these devices as well.
Values indicated with asterisks are measured using the UL (JIS) methods.
Leakage Breaker Connection Example
H Improving Encoder Cable Noise Resistance
The OMNUC W Series uses serial encoders, with phase-S signals from the encoder. The phase-S com-
munications speed is 4 Mbits/s.
In order to improve the encoder’s noise resistance, take the following measures for wiring and installa-
tion.
• Always use the specified Encoder Cables.
• If lines are interrupted in the middle, be sure to connect them with connectors, making sure that the
