5. COMMISSIONING

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.

WARNING

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

All the features of the 6SE21 inverter may be controlled via the RS485 serial interface. 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.

CAUTION

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.

WARNING

5.1.1 Starting and Stopping the Inverter

This equipment uses dangerous voltages and controls rotating mechanical machinery.

Dangerous voltages are present on the equipment even after switching off. Isolate elsewhere before
attempting to work on the equipment.

Under certain operating conditions the inverter can restart automatically after an input power failure.
Ensure that no one is close to machinery controlled by the inverter when such conditions prevail.

DEATH or SERIOUS INJURY can result if the above precautions are not observed.

WARNING

The method of starting and stopping the inverter depends on the setting of parameter P05. One of three different
methods of control may be used in conjunction with one of two different run–down modes. An additional run–down
mode which uses dc injection braking may be enabled by adjusting parameter P11.
