1. When using an operation pattern in which the regenerative resistor is used at a high frequency, the
surface of the resistor may exceed 300°C, so take care to the installation and the heat radiation.
Do not install the resistor in a place where it can be easily touched by hand or body parts as
touching could lead to burns. Install a well-ventilated protective cover (punched metal, etc.) if body
parts might come in contact.
CAUTION
2. Installation of the regenerative resistor on a metallic surface outside the panel is recommended to
improve the heat radiating effect.
3. Install the regenerative resistor so that the section where the lead wires are led out is not at the top
of the resistor.
