8 Technical Data of LGT Safety Light Grid
1
) A power supply unit with safeguarded isolation
(SEL V, PEL V circuit) must be used.
2
) The voltage must not exceed or fall below the
limit values.
Caution: In the event of high-energy overvoltages
between DC supply and PE potential (
≥
0.5 kV)
a switch to AC supply and/or insulated mounting
of the sensor strips is recommended. In case of
interference also lay the sensor cables isolated
from the interfering cable duct.
3
) Cannot be shortened.
