Not connected
Device versions with a pre-installed
M12 socket are ready-wired upon
delivery.
Version without a pre-installed M12
socket
1.
Insert an M12 socket
(accessory) into a suitable
opening in the base of the
housing.
2.
Connect the cable to a
Memosens terminal as per the
wiring diagram.
Connecting the sensor
‣
Plug the connector of the sensor
cable (→ 47item 1) directly into
the M12 socket.
Please note the following:
• The internal device wiring is always
the same regardless of what kind of
sensor you connect to the M12
socket (plug&play).
• The signal or power supply cables
are assigned in the sensor head in
such a way that the PK and GY
power supply cables are either used
(e.g. optical sensors) or not (e.g. pH
or ORP sensors).

WARNING
Module not covered
No shock protection. Danger of electric shock!
‣
Change or extend the hardware: always fill the slots from left to right. Do not leave any
gaps.
‣
If all of the slots are not occupied: always insert a dummy cover or end cover in the slot
to the right of the last module(→ 2, 10). This ensures that the unit is shock-
protected.
‣
Always ensure shock protection is guaranteed particularly in the case of relay modules
(2R, 4R, AOR).
The terminal strip (cabinet unit) is used to connect the cable shields.
