5.5.3 Connecting the photoelectric probes
Use a cable with 3 x 1 mm² to extend the probe cable. Use shielded
cables for lengths of more than 15 m. The maximum length of the probe
cables is 50 m. Use underground cables such as NYY 3 x 1.5 mm² for
underground cable installation.
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.
1. Route the probe cable through the cable gland at the right.
