status”.
Separate this earth ground line from others, like ground line of a motor, inverter or a power source. Unless the
convertor is grounded, it may result in receiving an electric shock, cause operation error or catch fire.
Proper Power Source And Power Cable
Confirm the AC voltage, frequency and power tolerance of the power cable (refer to “4. Power Terminal”). If the
voltage range of the cable is lower than the power line voltage, it may cause leakage or catching fire. Use pole
compression terminals to connect the power cable to the terminals.
Splashing Water
The module is not water-resistant type.
Flammable Gas
Do not install the convertor where flammable gas is present.
Heat Radiation Of The Module
Space out instruments to radiate heat sufficiently.
Do not use in an environment where the ambient temperature exceeds the operating temperature range [-10
℃
to
+50
℃
, 85% RH or less (no condensation)].
