Stop!
Special commissioning procedure after long−term storage
If controllers are stored for more than two years, the insulation resistance of
the electrolyte may have changed.
Possible consequences:
ƒ During initial switch−on, the DC−bus capacitors and hence the controller are
damaged.
Protective measures:
ƒ Form the DC−bus capacitors prior to commissioning. Instructions can be
found on the Internet (www.Lenze.com).
)
Note!
ƒ Do not change the switch−on sequence.
ƒ In the event of a fault during commissioning please see the chapter
"Troubleshooting and fault elimination".
In order to avoid personal injuries or material damage, check the following before
connecting the mains voltage:
ƒ The wiring for completeness, short circuit, and earth fault
ƒ The "emergency stop" function of the system
ƒ The motor circuit configuration (star/delta) must be adapted to the output voltage
of the controller.
ƒ If no function module is used, the FIF cover has to be fitted (delivery status).
ƒ If the internal voltage source X3/20, e.g. of the standard I/O is used, terminals X3/7
and X3/39 have to be bridged.
