3. Product description
3.1 Device description
The device is:
·Designed for measuring power quality accord-
ing to EN61000-4-30 in building installations, in
distribution boards, circuit breakers and busbar
trunking systems.
·Suitable for installation in stationary and weath-
er-protected switchboards indoors.
·Suitable for use in 2-, 3- and 4-conductor net-
works and in TN and TT networks.
·Intended for current measurement via external
../1 A or ../5 A current transformers.
·Suitable for measurements in medium and high
voltage networks only with the use of current
and voltage transformers.
·For use in residential and industrial areas.
·Suitable for residual current measurement (RCM)
via external residual current transformers with a
nominal current of 30 mA.
·Not an independent protective device against
electric shock.
The measurement results can be displayed and
read out and further processed via the interfaces
of the device.
This operating manual only describes the opera-
tion of the device via the 6 buttons. The GridVis®
network analysis software has its own "online
help".
CAUTION
Malfunction and damage of the device or risk of
injury due to improper connection.
Improperly connected devices can deliver incorrect
measured values, damage the device or pose a
risk of injury to persons.
Observe the following:
· That measured voltages and currents come
from the same network.
· Do not use the device for measuring direct
current!
· Ground current-conducting switchboards!
CAUTION
The residual current measurement monitors the
residual currents via external current transform-
ers and, if a threshold
value is exceeded, can trigger a warning signal.
The device is therefore not an independent
protective device against electric shock.
3.2 Incoming goods inspection
The prerequisites for trouble-free and safe op-
eration of this device include proper transport,
storage, setup and assembly, as well as proper
operation and maintenance.
Exercise due caution when unpacking and pack-
ing the device, do not use force and only use
suitable tools.
Check the devices for flawless mechanical condi-
tion by visual inspection.
Please check the scope of delivery for complete-
ness before you start installing the device.
If it can be assumed that safe operation is no
longer possible, the device must be taken out
of operation immediately and secured against
unintentional start-up. It can be assumed that safe
operation is no longer possible if the device, for
example:
·has visible damages,
·no longer functions despite an intact power
supply,
·was subjected to extended periods of unfavor-
able conditions (e.g. storage outside of the per-
missible climate thresholds without adjustment
to the room climate, condensation, etc.) or trans-
port stress (e.g. falling from an elevated position,
even without visible external damage, etc.).
3.3 Intended use
The device is:
·Only for use in the industrial sector.
·Intended for installation in switchboard cabinets
and small distribution boards.
·Not intended for installation in vehicles! Use of
the device in non-stationary equipment consti-
tutes an exceptional environmental condition
and is only permissible by special agreement.
·Not intended for installation in environments with
harmful oils, acids, gases, vapors, dusts, radia-
tion, etc.
·Designed as an interior meter.
Safe and trouble-free operation of the device
requires proper transport, storage, assembly,
installation, operation and maintenance.
