7.2 Disconnect switch
Install a suitable circuit breaker for the supply volt-
age in the building installation in order to discon-
nect the device from voltage and current.
·Install the circuit breaker near the device and
within reach of the user.
·Mark the circuit breaker as the isolation device
for this piece of equipment.
7.3 Supply voltage
Operation of the device requires a supply voltage.
The type and level of the supply voltage for your
device can be found on the rating plate. Also note:
·Before applying the supply voltage, ensure that
the voltage and frequency match the specifica-
tions on the rating plate.
·Connect the supply voltage via a UL/IEC ap-
proved fuse to the plug-in terminals on the rear of
the device.
·After connecting the supply voltage, the display
appears. If no display appears, check whether
the supply voltage is within the nominal voltage
range.
NOTE
·The device optionally allows the connection of
100 V voltage transformers!
·
The following applies for the UMG 96-PA-
MID / MID+ when measuring voltage using
voltage transformers: Use calibrated/permis-
sible voltage transformers for MID-compliant
measurement (secondary: 3 x 57.7/100 V -
3 x 230/400 V)!
