mounting and start-up have been completed.
7.1 Degree of protection
Devices with a rating of IP 54 can be con -
verted to a rating of IP 65 by exchanging the
filter in the enclosure cover.
7.2 Manual override
The devices can be optionally fitted with a
manual override to allow the device to be
manually operated when a nominal signal is
not available:
− As switch in the enclosure cover
− As pushbutton in the enclosure cover
− As pushbutton underneath the enclosure
cover
We recommend using devices without man-
ual override for safety circuits.
