• Have connection conducted by professionals. If electric circuits must be touched during connection after
power-on, turn the power supply side circuit breaker off (open) to avoid electric shock.
Electric shock or fire may result.
• Even after the circuit breaker is turned off (to open the circuit), the smoothing capacitors remain charged; wait
until the CHARGE lamp of the converter is unlit and measure the DC voltage of the converter with a
multimeter or the like to check that the voltage has dropped below the safe level.
Electric shock may result.
• Do not use a product having a broken or missing part.
