yy This product cannot be used in IT power distribution systems.
yy Install the product within the enclosure in order to avoid contact with
hands.
yy When a product can be touched with hands, be sure to ground. Make sure
to ground the Protective Earth Terminals of the motor and driver.
yy To protect against electric shock using an earth leakage breaker (RCD),
connect a type B earth leakage breaker to the primary side of the driver.
yy When using a circuit breaker (MCCB), use a unit conforming to the EN or IEC
standard.
yy Isolate the motor cable, power-supply cable and other drive cables from the
signal cables by means of double insulation.
yy The temperature of the driver's heat sink may exceed 90 °C (194 °F)
depending on the driving conditions. Accordingly, take heed of the
following items:
• Do not touch the driver.
• Do not use the driver near flammable objects.
• Always conduct a trial operation to check the driver temperature.
