The cables plugged into the connections are screwed tight.
If these instructions are not complied with, the IP enclosure rating for the device is not
guaranteed!
5.2 Notes on UL approval
The device shall be supplied from an isolating transformer having a secondary overcur‐
rent protective device that complies with UL 248 to be installed in the field rated either:
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
5.3
Electrical installation
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 10mm. 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 table 2 and table 4. Retighten
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.
