5.8.1 Connect probe
To extend the probe cable, use a cable (Ø 5 ... 9 mm) for intrinsically safe
circuits (2 x 1 mm²). Use shielded cables for lengths of more than 5 m.
The maximum length of the probe cable is 50 m.
Verify that the probe cable is sufficiently protected from damage (for
example, by installing it in a metal pipe).
Verify that the probe cable is not routed immediately next to or together
with cables carrying mains voltage.
Verify that the probe cable used is marked (for example, light blue as per
EN 60079-14).
1. Route the probe cable through the blue cable gland at the right.
2. Connect the wires of the probe cable to the terminal with the designa-
tion "Sonde".
Route the probe cable in such a way that the probe can be removed from
the container for leak detection fluid for function tests. Do not shorten the
probe cable.
If the control unit and the container for leak detection fluid are in separate
rooms, the probe may only be connected to the control unit by means of
a suitable fitting (see Figure 8 on page 33).
