Practical guidance on use
This device is only to be deployed and used
by qualified personnel in accordance with the
safety provisions and regulations.
When using the device, the necessary legal
and safety regulations for the respective use
are also to be observed.
Qualified personnel are persons who are fa-
miliar with the setup, installation, putting into
service and operation of the product and have
the necessary qualifications for their work, e.g.
- Training or instruction and/or authorisation
to switch electric circuits and devices on and
off, to isolate them, earth and label them in
accordance with the safety standards.
- Training or instruction in accordance with the
safety standards for the maintenance and use
of appropriate safety equipment.
Attention!
If the device is not operated in accord-
ance with the operating instructions,
protection is no longer ensured and
the device can cause hazards.
Intended use
Installation
The UMG507 is suitable for installation in
fixed and weatherproof control panels. Con-
ductive control panels must be earthed. Due
to its high immunity the UMG507 is suitable
for continuous, unmonitored operation.
Measurement
The UMG507 is inetnded for the measure-
ment of electrical variables such as voltage,
current, power, etc. in low-voltage switchgear.
Measured values are saved adn can be read
out through serial interfaces. The voltage and
current measurement inputs are continuously
scanned. Brief interruptions up to a half-wave
are reliably detected.
The applied voltages must lie within the meas-
uring and supply voltage range given on the
rating plate.
The measuring and supply voltages must be
connected to the UMG507 via a disconnect-
ing device (switch or circuit-breaker) and an
overcurrent protection device (2-10A) in the
building installation. The disconnecting device
must be near the UMG507 and be easily
reached by the user. The disconnecting device
must be labelled for the device.
Either ../5A or ../1A current transformers can
be optionally connected to the current mea-
surement inputs.
Medium and high-voltage systems
Measurement in medium and high-voltage
systems is generally carried out using cur-
rent and voltage transformers. Special safety
provisions are applied to these, which are not
discussed in any greater detail here.
