The Inverter can be set to operate a motor at high-speeds. Verify the speed
capability of motor and machinery prior to operating inverter.
Holding torque is not produced when using the DC-Brake function. Install separate
equipment when holding torque is required.
(5) Fault prevention precautions
If required, provide a safety backup such as an emergency mechanical brake to
prevent any hazardous conditions if the inverter fails during operation.
(6) Maintenance, inspection and parts replacement
Do not megger (hi-pot or insulation resistance) test the power or control circuit of the
inverter.
Refer to ‘Chapter 6 Troubleshooting and Maintenance’ and parts replacement details.
(7) Disposal
Handle the inverter as an industrial waste when disposing of it.
(8) General instructions
Many of the diagrams and drawings in this instruction manual show the inverter without a
cover. Prior to operating the unit, be sure to restore covers and circuit protection according to
specifications.
(9) Protective requirements
The accessible connections and parts listed below are of protective class 0, it means that the
protection of these circuits relies only upon basic insulation and becomes hazardous in the
event of a failure of the basic insulation. Therefore, devices connected to these circuits must
provide electrical-shock protection as if the device was connected to supply mains voltage. In
addition, during installation these parts must be considered, in relation with electrical-shock,
as supply mains voltage circuits.
