3. Product description
3.1 Device description
The device is a multifunctional network analyzer
and is suitable for:
·Measurements and calculations of electrical
quantities such as voltage, current, power, ener-
gy, harmonics current in building installations, on
distribution boards, circuit breakers and busbar
trunking systems.
·An expansion of the range of functions using op-
tional modules (maximum of 3 different modules).
·Measurements of voltages and currents from the
same network.
·Measurements in low voltage networks (3-phase
4-conductor systems) with rated voltages up to
L-L 400 V and L-N 230 V (overvoltage category
300 V CAT III).
·Measurements in medium and high voltage net-
works via current and voltage transformers.
·Current measurement via
- External ../1 A or ../5 A current transformers.
- Channel I5 (residual current measurement).
·Installation in stationary switch cabinets or small
distribution boards, in any mounting orientation.
·The measurement of residual currents (Residual
Current Monitoring, RCM) of an electrical sys-
tem. The measurement device is not a protective
device against electric shock!
·Use in industrial areas.
Measurement results are displayed by the mea-
surement device and can be read and processed
via interfaces.
3.2 Incoming goods inspection
Safe and trouble-free operation of this device and
its components presupposes proper transport,
proper storage, set-up and assembly as well as
operation and maintenance in addition to com-
pliance with the safety information and warning
notices.
Exercise due caution when unpacking and packing
the device, do not use force and only use suitable
tools.
Before installing the device, please check the
following:
·Its flawless mechanical condition by visual in-
spection.
·The scope of delivery for completeness.
If it can be assumed that safe operation of the
device is no longer possible:
·Disconnect the device from the mains immedi-
ately!
·Secure the device against being switched on
again!
It can be assumed that safe operation is no longer
possible if the device, for example:
·Has visible damage.
·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 transport
stress (e.g. falling from an elevated position, even
without visible external damage, etc.).
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 / direct voltage!
· Ground current-conducting switchboards!
