If the card is formatted already, all existing data will be deleted from the card! Before
inserting the card, check whether the SD card contains any data that must be backed up.

- For IP connections, connect the lines for the alarm inputs (for external devices such as
door contacts or sensors) to terminals IN1 and IN2 on the orange terminal block (see the
section "Terminal block" in the Appendix of the User Manual) of the encoder, and check
that the connection is secure. Connect each alarm input to a ground contact (GND). With
the appropriate configuration, an alarm sensor can automatically connect the encoder to
a remote location, for example.
Note: You can use a zero potential closing contact or switch as the actuator.
If possible, use a bounce-free contact system as the actuator.
- For physical alarm connections on MIC IR power supplies, connect alarm input cables to
terminal block HD2, as indicated in the table below:

outputs (for switching external units such as lamps or alarm sirens) to terminals R1 and
R2 on the orange terminal block of the encoder, and check that the connection is secure.
You can operate these relay outputs manually while there is an active connection to the
encoder. The outputs can also be configured to activate sirens or other alarm units
automatically in response to an alarm signal.
and 200 mA (SELV) may be applied to the relay contacts.
