5. Electrical connections
Connect the electrical conductors accoeding to the
instructions on 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 prescri-
bed measurement must correspond to those
marked on the nameplate of the DCTR-XXXX
(
measuring input,
and
power supply, see Fig. 6)!
... the resistance in the output circuit may not over-
range the current output value
R
max. [kΩ] ≤
ext
(I
= current output value)
AN
... and not underrange the voltage output va-
lue
R
min. [kΩ] ≥
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!
