5. COMMISSIONING
WARNING
Hazardous voltages of over 750 V are used in the operation of this equipment.
Read the Warning Notice given at the start of section 4 before proceeding further.
The factory setting of 6SE21–series inverters allows them to be used immediately in many applications. However,
matching to specific applications can be accomplished easily by using the wide range of digital parameter settings
provided (see section 5.3) .
5.1 Preparation for Switch–On
CAUTION
All the features of the 6SE21 inverter may be controlled via the RS485 serial interface (see
section 7) . If this is how the inverter is to be used, remember that it may start and stop without
warning. Appropriate precautions must be taken to prevent accidents from occurring while the
inverter is being controlled in this manner.
If the inverter is to be operated by external remote controls connected via terminal block X11,
disable the integral controls to avoid misleading operation and possible damage to the inverter.
WARNING
Ensure that the cover is fitted correctly before switching on the inverter.
Wait at least five minutes after switching off before attempting to remove the plastic cover and
work on the equipment. This will allow time for the capacitors within the unit to discharge to a
safe level.
Failure to observe these precautions may result in serious injury or death.
