Safety measures When operating electrical devices, specific parts of these
devices inevitably carry dangerous voltage. As a result, serious personal
injuries or property damage can occur if they are not handled correctly: ·
Before connecting the device, ground it
at the ground wire connection if available. · Dangerous voltages may be
present in all
circuit parts connected to the voltage supply. · There may still be dangerous
voltages present
in the device even after it is disconnected from the supply voltage (capacitor
storage). · Do not operate equipment with open current transformer circuits. ·
Do not exceed the threshold values specified in the user manual and on the
rating plate. This must also be observed during inspections and commissioning.
· Observe the safety instructions and warning notices in the usage information
that accompanies the devices and their components!
WARNING
Danger due to noncompliance with warning and safety instructions.
Noncompliance with warning and safety instructions on the device itself and in

acids, gases, vapors, dust and radiation, etc. · designed as an indoor meter.
Incoming goods inspection The prerequisites for trouble-free and safe
operation of the devices and their components include proper transport,
storage, setup and assembly, as well as careful operation and maintenance.
Exercise caution when unpacking and packing the device, without using force
and only using suitable tools.
Check: · Devices and components by performing
a visual inspection to ensure a flawless mechanical condition. · The scope of
delivery (see user manual) for completeness before beginning the installation
of your devices and components.
If you assume that safe operation is no longer possible, shut down the device
with components immediately and secure it from being unintentionally started

functions, data, assembly and the battery used in the device in the user
manual.
Mount the measurement device in switch cabinets or small distribution boards
according to DIN 43880 (any installation position) on a 35 mm (1.38 in) DIN
rail (for type, see technical data), as follows: 1. Insert the bus connector
included in the scope
of delivery in the socket on the bottom of the measurement device. 2. Slide
your measurement device with the bus connector laterally on the DIN rail or
press it frontally onto the DIN rail until the bottom latch engages.
INFORMATION
Before starting with the DIN rail assembly and wiring for your UMG 801, make
sure that the bus connector is mounted on the bottom of your UMG 801. Up to 10
modules are connected via the bus connector.

Connecting the supply voltage
The supply voltage level for your device can be found on the rating plate or
in the technical data. After connecting the supply voltage, a display appears.
If no display appears, check whether the supply voltage is within the rated
voltage range.
ATTENTION
Noncompliance of the connection conditions or exceeding the permissible
voltage range can damage or destroy your device.
· The voltage and frequency must comply with the specifications on the rating
plate. Observe the limit values as described in the user manual.
· In building installations, secure the supply voltage with a UL/IEC-listed
circuit breaker/fuse.
· The circuit breaker – must be easily accessible for the user and located in
the vicinity of the device. – must be labeled for the respective device.
· Do not tap the supply voltage at the voltage transformers.
· Provide a fuse for the neutral conductor if the neutral conductor connection
is not grounded to the source.

INFORMATION
· The multifunction channels are suitable for the connection of residual
current transformers with a rated current up to 30 mA and have the function
“Check the current transformer connection”.
· The residual current monitoring monitors the residual currents via external
current transformers and, if a threshold value is exceeded, can trigger a
warning signal. The measurement device is not an independent protection device
against electric shock!
Recommendation: To configure the transformation ratio for the residual current
transformer, use the GridVis® software.
ATTENTION
Faulty cross currents, wrong measurements, up to damage to the device and / or
your system due to missing galvanic separations! Failure to galvanically
isolate active external CTs (or other current transmitters) on the
multifunction channels from the device power supply can result in faulty
cross-currents, incorrect measurements, or damage to your device and / or your
system. · Do not remove the auxiliary power supply of
active external current transformers (or other current generators) on the
multifunction channels from the supply voltage of the device! For each active
current transformer, use galvanically isolated power supply units (secondary
side). · Do not ground passive current transformers on the multifunctional
channels! Observe the usage information of the current transformer
manufacturer.

the voltage and current
measurement. · functional insulation against each other to the supply voltage,
the residual current and temperature measurement inputs, the digital
inputs/outputs and the analog output. The interfaces of the connected devices
require a double or reinforced insulation against supply voltages (according
to IEC 61010-1: 2010).

inputs for the voltage and current
measurement. · no insulation among each other and to the supply voltage.. ·
functional insulation to the Ethernet, RS485 interfaces, the

measuring transformers require a double insulation to the system parts that
have dangerous contact voltage (according to IEC61010-1:2010).
