Product name
Isolation transformer
■Installation of breaker or external fuse
Considering the rated current and inrush current of the power supply module, install a breaker having the appropriate sensing
property or an external fuse causing proper blowout.
When a single product is used, connecting a breaker around 10 A or an external fuse is recommended in order to protect the
power source.
■Power supply wiring
Do not install 100 VAC or 24 VDC wires bundled with or near the main circuit lines (high voltage and large current) or I/O
signal wires (including common lines). Keep a distance of 100 mm or more from these lines.
