5. Electrical connections
Connect the electrical conductors acc. to the instructions on
type label.
Make sure that all input cables are not live
(potential-free) when making the connec-
tions!
Impending danger by high power supply
voltage!
Take care of current transformers!
Also note that, ...
... the data required to carry out the prescribed
measurement must correspond to those
marked on the nameplate of the SINEAX I 552
(
measuring input,
and
power supply, see Fig. 6)!
... 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!
