Installation
Mounting
The UMG96S is designed for a fix installation in
low and medium voltage systems. The mount-
ing position is random.
Measurement and operation
voltage
The UMG96S gets its operating voltage from the
measuring voltage. The measurement is
designed for three phase systems with neutral
conductor (TN and TT networks). The measure-
ment and operational voltage must be con-
nected to the UMG96S via a separation (circuit
breaker or power switch) and a fuse (2-10A)
within the installation. The connection of the
measurement and operating voltage is carried
out on the backside of the UMG96S via touch
proof spring terminal.
300V standard version
At least one phase (L) of the UMG96S and the
neutral N must be connected and the connected
voltage must be within the measurement and
operation voltage range.
The measurement and
operation voltage
range
of devices without additional PCB and for
devices with additional PCB 1 (analogue output)
are:
L-N 85 .. 300V
L-L 148 .. 520V
The measurement and
operating voltage
range
for devices with additional PCB 2
(Profibus) are:
L-N 140 .. 300V
L-L 242 .. 520V
150V special version
At least 2 phases (L) of the UMG96S must be
connected, and the connected voltage must be
within the measurement and operation voltage
range.
The measurement and
operating voltage
range
is:
L-N 50 .. 150V
L-L 85 .. 260V
Attention!
Before connecting voltage, the device
should be deposited in the preposed in-
stallation room for at least 2 hours, in
order to create a temperature equaliza-
tion and avoid humidity or dew within the
instrument.
m
Attention!
The limits, mentioned under "technical
data" may not be exceeded, even not
during checking or putting into service of
UMG96S.
m
- The used cables must be suitable for a rated
voltage of 300VAC against ground.
- The measurement and operating voltage must
be protected by a fuse. The fuse must be in the
range of
2A to 10A
.
- Please provide a circuit breaker or power
switch for the operating voltage.
- The switch must be near the UMG96S and
easy to reach.
- The switch must be marked as a separation for
this instrument.
