CHAPTER 8 – OPERATION 113
8.6 Starting the drive
The procedure to start the drive is described below.
8.6.1 Checks before starting the drive
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.
8.6.3 Starting the drive locally
1. Check that the CDP control panel is connected
to the INU.
2. Enable the local control mode of the CDP con-
trol panel.
3.
This step applies to drives which
are equipped with the optional
safety relay.
If the EMERGENCY RESET pushbutton (option)
is flashing, press the pushbutton 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 flash.
The pushbutton also flashes if the emergency-
off pushbutton on the control compartment
door, or any other emergency-off switch linked
to the drive, is pressed. If the pushbutton con-
tinuous flashing, verify that there is no emer-
gency-off command active.
For further information, see 8.8 Emergency-off.
4. Check that no alarm or fault messages are dis-
played on the CDP control panel.
When a fault message is displayed on the CDP
control panel, reset the fault.
If a fault cannot be reset, it must be rectified by
the responsible personnel.
When no alarms and faults are active, and the
drive is ready, the CDP control panel displays
ReadyOn.
It is recommended to have the following
documents at hand when starting the
drive locally for the first time:
• Wiring diagrams
to identify the circuit
breakers
• Chapter 9 - CDP control panel for
information on functions and features
of the CDP control panel
Hazardous voltages!
All covers must be screwed in place to prevent
unintentional contact with energized components.
The manual release of the door safety switches
must be in the locked position. The locked position
prevents doors of medium voltage compartments
being opened unintentionally during operation.
