Installation9.2
The unit can be installed in any position.
The installation position should however
be selected carefully in order to ensure
that the display can easily be read.
The housing is made of impact-resistant
plastic. The upper section containing the
detection circuitry is a push connection
fit into the lower section. The connection
terminals, earthing strip and neutral bus
are located in the lower section. The up-
per section of the housing is attached to
the lower section using two screws.
The lower section can either be snapped
onto a DIN rail or secured with two M5
screws. In order to obtain enclosure
IP 54, two sealing washers must be
placed beneath the M5 screws.
The housing has 6 knock-out holes for
M16 plastic screw connectors.
