a) max 5 amps for voltages 0 ~ 20 V (0 ~ 28.3 V peak), or
b) 100 / Vp for voltages of 20 ~ 30 V (28.3 ~ 42.4 V peak).
Alternatively, they can be supplied from a Class 2 power supply.
UL Environmental Rating: Enclosure type 1
The sensors must be connected in a voltage-free state. The following information must
be observed, depending on the connection type:
– Plug connection: note pin assignment: when the cover is open, the male connector
can be swiveled horizontally and vertically.
– Terminal connection: note the permissible cable diameter of 5 to 10 mm. When
the cover is open, the M16 fitting can be swiveled horizontally and vertically.
Unscrew the M16 fitting and remove sealing plug. Lead voltage-free supply cable
through and connect sensor in accordance with
M16 fitting with seal so that the IP enclosure rating of the device is ensured.

Only apply voltage/switch on the power supply once all electrical connections have
been established.
