* Electric power available without running the built-in thermal protector.
For safety, a temperature fuse and a thermal protector are built in.
Configure the circuit so as to turn off the power supply when the thermal protector is running.
The built-in temperature fuse can break according to the radiation condition, the used temperature range, the
power supply voltage, and the load change.
Make sure that the surface temperature of regenerative resistor is being kept 100 deg. Celsius or less under
bad conditions (high power supply voltage, large load inertia, short deceleration time, etc.) subject to
regeneration by embedding the regenerative resistor in equipments and running the equipments.
Attach the regenerative resistor on the incombustibles such as metal.
Install the regenerative resistor so that people can not directly touch it, such as the incombustible to cover it.
Keep the temperature of places, which people can directly touch, below 70 deg. Celsius.
