4.1 Installation Safety
Read these warnings before starting the installation of the option board.
W A R N I N G
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.
C A U T I O N
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.
N O T I C E
Measure or do a check of the encoder supply voltage of the encoder interface board before connecting a new encoder. It is possi-
ble that the encoder supply voltage was set to a higher voltage than what is supported by the new encoder. An incorrect encoder
supply voltage can damage the equipment.
