Also note that, …
… the data required to carry out the prescribed
measurement must correspond to those mar-
ked on the nameplate of the SINEAX G 537
(
measuring inputs,
measuring output
and
power supply, see Fig. 5)!
… the resistance in the output circuit may not
overrange
the current output value

… 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!

5. Electrical connections
Connect the electric conductors acc. to the instructions on
type label.
Make sure that all input cables are not
live (potential-free) when making the
connections!
Impending danger by high input voltage
or high power supply voltage!
4. Mounting
The SINEAX G 537 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).
