Installation and putting into service
The installation and putting into service of the UMG96 should be carried out as follows:
-
Mount the device
- Connect measurement and supply voltage
Before connection of the measurement and supply voltage to UMG96, please ensure, that the net conditions
match the information on type plate.
The UMG96 can be delivered in three voltage varieties:
To ensure, that the connected measurement and supply voltage is within the allowed range, this must be
checked with an AC voltmeter before connecting the UMG96.
The connection wires for measurement voltage to the UMG96 must be suitable for voltages up to 300V against
ground and 520V phase to phase.
After switching on the measurement and supply voltage, shown on type plate, all segments on display appear.
If no indication appears, please check, if at least one (two) phase are within the rated voltage range. At devices
for the measurement in 230V/400V mains, at least one phase must be within the rated voltage range.
Program current and voltage transformers
When the device is delivered, a current transformer ratio of 5/5A is entered.
The voltage transformer ratio must be changed, if a voltage transformer is connected only.
While connecting a voltage transformer, please note the measurement and supply voltage of UMG96,
mentioned on type plate.
The program only allows current and voltage transformer ratios, which can lead to sum power of a
maximum of 99.9MW.
Connect current transformers
The current transformers (../5A or ..1A) are connected to the clamps k and l from the corresponding outer
conductors L1, L2 and L3. The current can be measured with an Amperemeter and compared with the indica-
ted current at the UMG96 to check. Please note, that the current transformer ratio is preset with 5/5A and
must be adapted to the used current transformers.
