Installation
Mounting place
The UMG96L is suitable for a fix insertion into
low and medium voltage switchgear. Any
mounting position is possible.
Measuring and operating voltage
The operating voltage of the UMG96L is gener-
ated by the measuring voltage. The measure-
ment is designed for three phase systems with
neutral conductor (TN and TT mains). The
measuring and operating voltages must be con-
nected to the UMG 96L via a separation (switch
or power switch) and an overcurrent protection
(2-10A) within the building installation.The con-
nection of the measuring and operating
voltages is carried out at the back side of the
UMG 96L via shock protected spring clamps.
230V/400V Standard version
Phase L1 and the neutral conductor N must be
connected, and the attached voltage must be
within the range of the measuring and operat-
ing voltage.
120V/220V Special version
Phase L1 and the neutral conductor N must be
connected, and the attached voltage must be
within the range of the measuring and operat-
ing voltage.
60V/110V Special version
Phase L1 and the neutral conductor N must be
connected, and the attached voltage must be
within the range of the measuring and operat-
ing voltage.
Attention!
Before the device is connected to volta-
ge for the first time, it should be depos-
ited the installation room for at least 2
hours, to create a temperature assimila-
tion and avoid condensation and dew.
Attention!
The limits indicated in the technical data
may not be exceeded, not even while
checking and putting into service of the
UMG 96L.
- The connection wires for the operating volta-
ge leading to the UMG96L must be suitable for
voltages up to 300V against ground.
- The measuring and operating voltage has to
be protected by a fuse, which must be in the
range of
2A to 10A
.
- A switch or power switch for the operating vol-
tage must be provided within the building instal-
lation.
- The switch has to be near the instrument and
easily accessible.
- The switch must be marked as separation for
this instrument.
