Commissioning
BA8230 135
Static can be discharged by touching a conducting, earthed surface on the unit (eg.
the zero bus or the ground point marked).
When working on the unit and motors it must be noted that motor cables may carry a
voltage even if the pulses are disabled. 8230 frequency inverter must be disconnected
from the mains supply for all work on motor cables and voltage levels must be
checked first.
After isolating the 8230 frequency inverter from the mains supply it is important to
note that the discharge time of the link capacitors can exceed one minute. Check the
voltage before starting work..
If you are working on the machine or the motor feed cables, the main switch on the
unit or the circuit breaker on the plant must be secured to prevent anyone from
switching on again.
An mat compliant with EGB

must be used. This mat may not be earthed if
commissioning work is being carried out with the unit switched on.
The general safety instructions on the second cover page and in section 3.1
must be observed.
Check that the drive may run without endangering personnel and materials
before switching on the mains supply. This must be ensured for the complete
commissioning procedure.
