4.1 General instructions
The instrument is designed for recessed installation in a front panel,
housing front plate or a switching cabinet door. The required cut-out
is 92 x 92 mm (3.63 x 3.63 in) according to EN 60529. When installed
correctly, protection rating IP 40 is guaranteed. As an alternative,
the instrument can be mounted into a switching cabinet or housing
by means of three screws (fixed with screws on rear of housing).
A mounting adapter for carrier rail mounting is optionally avail-
able in the scope of delivery (top hat rail 35 x 7.5 according to DIN
EN 50022/60715).
Note:
If the instrument is mounted via the screws or carrier rail, it must
always be inside a switching cabinet or protective case.
A SU 600 Ex is an auxiliary, intrinsically safe instrument and may not
be installed in explosion-endangered areas.
Before setup, the Ex separating chamber must be attached to the
sensor input. Safe operation can be only ensured if the operating in-
structions manual and the EG type approval certificate are observed.
SU 600 Ex must not be opened.
