Alert Statements in this Manual
Caution
Be sure to use the specified Braking Resistor or Braking Resistor Unit.
Not doing so may occasionally result in moderate burns due to heating of the
Braking Resistor or Braking Resistor Unit.
When using a Braking Resistor or Braking Resistor Unit, be sure to install a
thermal relay to monitor the resistor temperature.
Include a sequence to turn OFF the power supply to the Inverter if the Braking
Resistor or Braking Resistor Unit overheats.
Terminals B1 and B2 are for connecting an optional Braking Resistor or Braking
Resistor Unit. Do not connect any device other than a Braking Resistor or Brak-
ing Resistor Unit to these terminals.
Doing so may occasionally result in moderate fire, heating, or equipment dam-
age.
Do not open terminal covers while the power is being supplied or for at least
one minute after the power has been turned OFF.
Doing so may occasionally result in minor injury from electrical shock.
Do not remove the fan cover except when replacing the fan. Before replacing
the fan, first turn OFF the power and disconnect the wiring.
Doing so may occasionally result in minor injury from electrical shock.
Install external breakers (MCCB) suitable for the Inverter capacity on the power
supply side of the Inverter and take other safety measures against short-circuit-
ing in load wiring.
Not doing so may occasionally result in property damage from short-circuiting
in load wiring.
Cover the Inverter or take other measures to prevent filings or lead clippings
from entering the Inverter during installation and wiring.
The Inverter contains high-voltage components and Inverter damage or prop-
erty damage may occasionally occur if the high-voltage components are short-
circuited.
