8.6 Starting the drive
8.6.1 Checks before starting the drive
!
Hazardous voltage!
All covers must be screwed in place to prevent
unintentional contact with energized components.
The manual release of the safety switch must be in
the locked position to prevent the door of the
medium voltage compartment being opened
unintentionally during operation.
When the drive is put into service after it has been
commissioned, or after it has been taken out of
service for a longer period, check the drive accord-
ing to the following list:
• Check that no tools and foreign objects are left
inside the cabinet.
• Check that all auxiliary power supplies from
external sources are switched on.
• Check that all internal circuit breakers of the
drive are closed.
• Check that all covers are mounted and the
doors are closed, locked and / or bolted.
• Check that the grounding switch is in position
not grounded.
• Check that the MCB is in operating position.
• Check that there is no run interlock active.
8.6.2 Starting the drive from remote
When the drive is operated from remote through a
higher-level control system or an operator control
desk, follow the instructions in the appropriate
manuals.
It is recommended to have the following
documents at hand when starting the
drive locally for the first time after com-
missioning:
• Appendix D – Wiring diagrams to iden-
tify the circuit breakers to be switched
on
• Chapter 9 - CDP control panel for
information on functions and features
of the CDP control panel
DANGER
8.6.3 Starting the drive locally
—
The motor is controlled by the
INU of the drive. For this reason,
the CDP control panel must be
connected to the INU to be able
to start up the drive locally. The
CDP control panel is only con-
nected to the AFE if it is required
to view status and fault messages
of the AFE.
When the drive is running, the CDP control panel
can be connected back and forth without inter-
rupting the operation of the drive.
However, to stop the drive, the CDP control panel
must be connected to the INU. Switching the CDP
control panel from the INU to the AFE and back is
done with the drive selection mode.
For further information, see
mode.
1. Check that the CDP control panel is connected
to the INU.
2. Enable the local control mode of the CDP con-
trol panel.

This step only applies to drives
which are equipped with the
optional safety relay.
If the EMERGENCY RESET pushbutton (option)
is flashing, press the EMERGENCY RESET push-
button to cancel flashing.
Each time the auxiliary voltage is switched off
and on again, the emergency-off safety relay of
the drive is actuated and lets the EMERGENCY
RESET pushbutton flashes.
The EMERGENCY RESET pushbutton also
flashes if the EMERGENCY OFF pushbutton on
the control compartment door, or any other
