1. Connect the connection cable to the module temperature sensor (see the manufacturer manual).
For this purpose, trim the unused insulated wires up to the cable shield and note the wire colours.
2. Connect the connection cable to the five-pole plug as follows:
• Release conductor entry 1 using a screwdriver and insert the insulated wire of the single core
into the conductor entry.
• For two-conductor connection, release conductor entries 3 and 4 using a screwdriver and
insert the insulated wires of the connection cable into the conductor entries. Observe the pin
assignment.
• For four-conductor connection, release conductor entries 2, 3, 4 and 5 using a screwdriver
and insert the insulated wires of the connection cable into the conductor entries. Observe the
pin assignment.
3. Insert the five-pole plug at terminal X7 into pin row B.
4. On the connection cable, mark the terminal and pin row to which the connection cable is
assigned. For this purpose, use the cable ties with the caption field.
5. On the supplementary sheet for noting the connected devices, note the terminal to which the
sensor is assigned.

6.10.3 Connecting Additional Sensors

Depending on whether you are using an irradiation sensor (see Section 6.10.1), you can connect a
maximum of 3 sensors to the analogue current outputs and 1 sensor to the analogue voltage input
X8 of the Cluster Controller.
Display of measured values at terminal block analogue voltage input 4 (AI4)
If no sensor is connected to the terminal block Analogue voltage input 4 (AI4), a measured
value for this terminal block of up to 2.2 V will nevertheless be shown on the display and the
user interface of the Cluster Controller.
• In order for a measured value of 0 V to be displayed for the terminal block
Analogue voltage input 4 (AI4) when it is not connected, place a jumper wire at
terminal X8 between pin B5 and pin B7.
Connecting Sensors to the Analogue Current Inputs
Additional required accessories (not included in scope of delivery):
☐ Up to 3 sensors
☐ Up to 3 connection cables (for cable requirements, see Section 6.3)
