Voltage measurement

You can use the UMG 96-PA to measure volt-
age in TN and TT systems.
Voltage measurement in the UMG 96-PA is
designed for the overvoltage category 600V
CATIII (measurement surge voltage 6 kV).

In systems without N, the measurement val-
ues that require an N are based on a calcu-
lated N.

WARNING!

Risk of injury from electric

voltage!

If voltage transformers are used, the con-
nections on the secondary side may

not

short-circuited!

For this reason, please note the follow-
ing:

•

Check that the
voltage transformers have been prop-
erly installed. To do this, read the re-
spective information about the voltage
transformers.
