TC-Double (+) X2
Connection via plug
The device is equipped with connectors according to EN 175301-803 for mains and status output. If the cables are mounted prop-
erly, they cannot be interchanged. Please make sure that the connectors are remounted correctly after connecting the cable. The
following figures show the pin assignment with respect to the numbers printed on the connector.
The supply line cross-sections must be suitable for the rated current. Use a maximum line cross-section of 1.5 mm² (AWG 16) and
a cable diameter of 8 - 10 mm (0.31 - 0.39 inch).

* When using an alarm contact connect to ≥ 33 V AC or ≥ 70 V DC PE voltage.
The clamping areas for S1 and S2 are 8 - 10 mm (0.31 – 0.39 inch) in diameter.
4.4 Signal outputs
The device has various status signals. The maximum switching power of the alarm outputs is 250 V AC/150 V DC, 2 A, 50 VA,
each.
An alarm is triggered by the alarm contact / status output (S2) if the temperature in block 1 is outside the specified limits. It does
not indicate if the alarm was triggered due to excess temperature or insufficient temperature.
