Caution Do not touch the Inverter radiator, regenerative resistor, or Servomotor while
the power is being supplied or soon after the power is turned OFF. Doing so
may result in a skin burn due to the hot surface.
Caution Do not conduct a dielectric strength test on any part of the Inverter. Doing so
may result in damage to the product or malfunction.
Caution Take appropriate and sufficient countermeasures when installing systems in

•
Locations close to power supplies.
The Unit refreshes I/O even when the program is stopped (i.e., even in
PROGRAM mode). Confirm safety thoroughly in advance before changing
the status of any part of memory allocated to I/O or the Inverter. Any changes
to the data allocated to any of these may result in unexpected operation of
the loads connected to the Unit or Inverter. Any of the following operation
may result in changes to memory status.
•
Transferring I/O memory data from a Programming Device to the Unit.
•
Changing present values in memory with a Programming Device.
•
Force-setting/-resetting bits with a Programming Device.
•
Transferring I/O memory from a host computer or from another PLC on a
network.
Do not attempt to take any Unit apart while the power is being supplied.
Doing so may result in electric shock.
