4. Mounting
The SINEAX U 553 can be mounted on a top-hat rail.
Note
“Environmental conditions”
in Section
“3. Technical data” when determining the place of
installation!
Simply clip the device onto the top-hat rail (EN 50 022) (see
Fig. 1).

5. Electrical connections
Connect the electrical conductors acc. to the instructions
on type label.
Make sure that all input cables are not live (po-
tential-free) when making the connections!
Impending danger by high input voltage or
high power supply voltage!
Also note that, …
… the data required to carry out the prescribed
measurement must correspond to those mar-
ked on the nameplate of the SINEAX U 553
(
measuring input,
measuring output and
power supply, see Fig. 5)!
… the resistance in the output circuit may not

… the measurement output cables should be twisted
pairs and run as far as possible away from heavy
current cables!
In all other respects, observe all local regulations when
selecting the type of electrical cable and installing them!
