90 Start-up
WARNING!
Before you activate the automatic fault reset or automatic restart functions of the
drive control program, make sure that no dangerous situations can occur. These
functions reset the drive automatically and continue operation after a fault or supply
break. If these functions are activated, the installation must be clearly marked as
defined in IEC/EN 61800-5-1, subclause 6.5.3, for example, "THIS MACHINE
STARTS AUTOMATICALLY". If you select an external source for the start command
and it is on, the drive will start immediately after fault reset. See the firmware
manual.
Start-up procedure
Action
Basic checks with no voltage connected
Disconnect all dangerous voltages from the drive and make sure that it is safe to start the work. Do
the steps in section
Electrical safety precautions (page
Make sure that the mechanical and electrical installation of the drive is completed. See
checklist of the drive (page
Check the settings of breakers/switches in the auxiliary circuits.
If time relays, or relays with delayed make-contact or break-contact are used, for example, in emergency
stop circuits, check the relay time settings. See the delivery-specific circuit diagrams and safety function
specific documentation (if applicable).
Make sure that both circuits of the XSTO connector are closed for the supply unit to start. (IN1 and
IN2 must be connected to OUT.) The control program enables the start/stop control only with both
circuits closed. See delivery-specific circuit diagrams and safety function specific documentation (if
applicable).
Connecting voltage to input terminals and auxiliary circuit
Make sure that it is safe to connect voltage:
• nobody is working on the unit or circuits that are wired from outside into the cabinets
• covers of the motor terminal boxes are on
• the disconnecting device [Q1] is open.
Remove the temporary grounding system (if installed).
Close the circuit breakers supplying the auxiliary circuits [F22, ..., F26].
Close the cabinet doors.
Close the main breaker of the supply transformer.
Close the auxiliary voltage switch [Q21].
