① Easily removable and visible.
② PE bars are to be installed preferably on the mounting plate. In case
of isolated PE bars, both ends are to be connected to the mounting
plate by means of copper strips with a maximum length of 20 cm. The
cross-section of the copper strips has to be at least equal to that of the
incoming mains cable.

0.75 mm 2 , up to 6 m and 1.5 mm
power supply unit is required!
④ Polarity reversal of the X1.1 connector might destroy the operator ter‐
minal, if there is no additional external protection (fire hazard). The
reason for this is the grounding of the 0 V in the operator terminal and
simultaneously to that the grounding of the 0 V load (PELV).

WARNING
● Supply the device only with voltage sources that feature protective ex‐
tra-low voltage (e.g. SELV or PELV according to EN 61131-2).
● Connect only voltages and circuits to connectors, terminals and interfa‐
ces up to 50 V nominal voltage that ensure safe isolation to dangerous
voltages (e.g. by sufficient isolation and electric strength).
NOTICE
The DC 24 V power supply of the hand-held terminal has to be fused appro‐
priately in the end application! The max. allowed fuse is 2 A.
