10.6 Replacing the Option Board

SHOCK HAZARD FROM CONTROL TERMINALS
The control terminals can have a dangerous voltage also when the drive is disconnected from mains. A contact with this voltage
can lead to injury.
-
Make sure that there is no voltage in the control terminals before touching the control terminals.
DAMAGE TO OPTION BOARDS
Do not install, remove, or replace option boards on the drive when the power is on. Doing this can cause damage to the boards.
-
Switch off the AC drive before installing, removing, or replacing option boards on the drive.
FAULTY OPTION BOARD
Indications of a faulty option board can be, for example, constant faults that indicate internal faults of the option board. Even if
the option board works correctly some of the time, there can be underlying faults that can create unexpected situations and
cause damage to the equipment.
-
Replace an option board when it is suspected to be faulty.
REPAIRING THE OPTION BOARD
Unsuccessful repair work can cause damage to the equipment. Return faulty option boards to the manufacturer for analysis.

Do not perform any repair work on the option board.
Find out if your software and parameter file version are supported by the new hardware version.
Parameterize the new option board. It can be necessary to load the existing parameter file from the current option board.
Changing the option board can affect the operation of whole safety system. It can be necessary to revalidate the safety system.
Changes may be due to different hardware versions or faults in either the old or new option board.
