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 power supply
voltage!
Take care of current transformers!
Also note that, ...
... the data required to carry out the prescribed
measurement must correspond to those mar-
ked on the nameplate of the SINEAX I 552
(
measuring input,
power supply, see Fig. 6)!
... the resistance in the output circuit may not over-
range the current output value
max. [kΩ] ≤
R
ext
(I
= current output value)
AN
... and not underrange the voltage output va-
lue
min. [kΩ] ≥
R
ext
... (U
= voltage output value)!
AN
... 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!
