WARNING
Do not operate current transformers in no-load mode!
Please note that many manufacturers do not permit their current transformers to be operated in no-load
mode! Connect the EL3413 to the secondary windings of the current transformers before using the current
transformer!

WARNING
Earthing of the terminal point N when measuring current!
If you do not connect the terminal point N with the neutral conductor of your mains supply (e.g. if the termi-
nal is used purely for current measurements) and use the I
N
current measurement channel, terminal point N
should be earthed, in order to avoid dangerous overvoltages in the event of a current transformer fault.
Earthing of the N point is not absolutely necessary if only the galvanically isolated current channels are
used.
