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 Resis-
tor 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 Braking
Resistor Unit to these terminals.
Doing so may occasionally result in moderate fire, heating, or equipment damage.
Install external breakers (MCCB) suitable for the Inverter capacity on the power sup-
ply side of the Inverter and take other safety measures against short-circuiting 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 property
damage may
occasionally occur if the high-voltage components are short-cir-
cuited.
