4. Mounting
The SINEAX U 539 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 leads acc. to the instructions on nameplate.
Make sure that all cables are not live 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 539
(
measuring input,
measuring output
and
power supply, see Fig. 6)!

current cables!
In all other respects, observe all local regulations when
selecting the type of electrical cable and installing them!
