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,
energy, harmonics current in building
installations, on distribution boards, circuit
breakers and busbar trunking systems.
·A modular extension of the functional scope
using current measuring modules.
·The connection of remote measurement points
in the switchboard cabinet or small installation
distributors via transfer modules.
·Measurements of voltages and currents from the
same network.
·Measurements in low-voltage networks (3-phase
4-conductor systems) in which nominal voltages
of up to 480 V from conductors to ground and
surge voltages of overvoltage category III occur.
·Measurements in medium and high voltage
networks via current and voltage transformers.
Measurements in medium and high voltage
networks are carried out via current and voltage
transformers!
·Current measurement via
- external ../1 A or ../5 A current transformers.
- the multifunction channels (mA current inputs).
·Installation in stationary switch cabinets or small
distribution boards, in any installation orientation.
·The measurement of residual currents (Residual
Current Monitoring, RCM) of an electrical system.
The measurement device is not a protective
device against electric shock!
·Use in residential and industrial areas.
Measurement results are displayed by the
measurement 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
compliance 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
inspection.
·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 operation
immediately!
·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
unfavorable conditions (e.g. storage outside
of the permissible 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!
·
Ground current-conducting switchboards!
