Maintenance And Service/Troubleshooting; Final Decommissioning - BONFIGLIOLI Active cube Operation Manual

Some components, e.g. the heat sink or brake resistor, may be hot even some time after the ma-

chine/plant was shut down. Don't touch any surfaces directly after shutdown. Wear safety gloves
where necessary.
The frequency inverter may hold dangerous voltage levels until the capacitor in the DC link is dis-

charged. Wait for at least 3 minutes after shutdown before starting electrical or mechanical work
on the frequency inverter. Even after this waiting time, make sure that the equipment is deener-
gized in accordance with the safety rules before starting the work.
In order to avoid accidents or damage, only qualified staff and electricians may carry out the work

such as installation, commissioning or setup.
In the case of a defect of terminals and/or cables, immediately disconnect the frequency inverter

from mains supply.
Persons not familiar with the operation of frequency inverters must not have access to the fre-

quency inverter. Do not bypass nor decommission any protective facilities.
The frequency inverter may be connected to power supply every 60 s. This must be considered

when operating a mains contactor in jog operation mode. For commissioning or after an emer-
gency stop, a non-recurrent, direct restart is permissible.
After a failure and restoration of the power supply, the motor may start unexpectedly if the Auto-

Start function is activated.
If staff are endangered, a restart of the motor must be prevented by means of external circuitry.
Before commissioning and the start of the operation, make sure to fix all covers and check the

terminals. Check the additional monitoring and protective devices according to EN 60204 and ap-
plicable safety directives (e.g. Working Machines Act or Accident Prevention Directives).
2.10.7

Maintenance and service/troubleshooting

Visually inspect the frequency inverter when carrying out the required maintenance work and

inspections at the machine/plant.
Perform the maintenance work and inspections prescribed for the machine carefully, including the

specifications on parts/equipment replacement.
Work on the electrical components may only be performed by a qualified electrician according to

the applicable rules of electrical engineering. Only use original spare parts.
Unauthorized opening and improper interventions in the machine/plant can lead to personal injury

or material damage. Repairs on the frequency inverters may only be carried out by the manufac-
turer or persons authorized by the manufacturer. Check protective equipment regularly.
Before performing any maintenance work, the machine/plant must be disconnected from mains
•
supply and secured against restarting. The five safety rules must be complied with.
2.10.8

Final decommissioning

Unless separate return or disposal agreements were made, recycle the disassembled frequency in-
verter components:
Scrap metal materials
•
Recycle plastic elements
•
• Sort and dispose of other component materials
Electric scrap, electronic components, lubricants and other utility materials must be
treated as special waste and may only be disposed of by specialized companies.
Always comply with any applicable national disposal regulations as regards environ-
mentally compatible disposal of the frequency inverter. For more details, contact the
competent local authorities.
