7. Starting up the product
Any installation, maintenance and inspection must be
carried out by trained persons.
Before you switch on the power supply, you must do the following:
•
Close the cover.
•
Make sure that all cable glands are tightened properly.
•
Make sure that there is no phase-to-phase and phase-to-
earth voltage on the output terminals.
•
Confirm continuity of the motor by measuring Ω values on U-V,
V-W and W-U.
•
Check for proper earthing of the frequency converter and the
motor.
•
Check that there are no loose connections on the terminals.
•
Confirm that the supply voltage matches the voltage of the
frequency converter and the motor.
7.1 Switching on the product
•
Confirm that the input voltage is balanced within 3 %. If not,
correct the input-voltage imbalance before proceeding. Repeat
this procedure after the voltage correction.
•
Make sure that the wiring of any optional equipment matches
the installation application.
•
Make sure that all operator devices are in the OFF position. The
panel doors must be closed, and covers must be securely
fastened.
•
Apply power to the unit, but do not start the frequency converter
yet. For units with a disconnect switch, turn it to the ON position
to apply power to the frequency converter.
7.2 Activating the optional STO function
The STO function is activated by removing the voltage at terminal
37 of the frequency converter. By connecting the frequency
converter to external safety devices providing a safe delay, an
installation for a Safe Stop 1 is obtained. External safety devices
need to fulfil Cat./PL or SIL when connected to terminal 37.
The STO function can be used for the following motor types:
•
asynchronous
•
synchronous
•
permanent magnet motors.
When terminal 37 is activated, the frequency converter issues an
alarm, trips the unit and coasts the motor to a stop. A manual
restart is required. Use the STO function to stop the frequency
converter in emergency stop situations. In normal operating mode,
the STO terminal 37 must be deactivated to start the motor.
A successful commissioning test of the STO function is
required after the initial installation and after each
subsequent change to the installation.
