Incoming inspection

Error-free and safe operation of this device

requires proper transport and storage, setup

and assembly and careful operation and mait-

ennance. If it can be assumed that safe opera-

tion is no longer possible, the device must be

immediately taken out of service and secured

against accidental startup.

The device must be packed and unpacked

with the usual care without force and only us-

ing suitable tools. The devices are to be visu-

ally inspected for faultless mechanical condi-

tion. Please note the installation instructions

enclosed with the device.

It is to be assumed that safe operation is no

longer possible if the device e.g.

• has visible damage,

• no longer works despite an intact power

supply,

• has been exposed to unfavourable condi-

tions for a lengthy time (e.g. storage outside

the permissible climate limits without adjust-

ment to the room climate, condensation, etc.)

or transport loads (e.g. fall from a large height

even without visible external damage, etc.).

Please check for complete scope of delivery

before starting to install the device.

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.

Product Description

TN and TT systems

Measurement is designed for 3-phase sys-

tems with neutral conductors (TN and TT

systems).

tem.

with N.

Fig. Block diagram, UMG507 in the IT system

without N.

IT systems

The UMG507 is only conditionally suitable for

use in IT systems, as the measurement volt-

age is measured at the housing potential and

the input impedence of the device causes a

leakage current to the earthing. The leakage

current can cause the insulation monitoring

in IT systems to respond. It must also be en-

sured that the maximum permissible voltage

at the inputs of the UMG507 are not exceeded

to earth (e.g. in case of a phase-to-earth fault).

The connection options shown in Fig. 4.1b

(with PEN conductor) or Fig. 4.6a (without a

PEN conductor) are suitable for IT systems

without restriction. Here the IT system is insu-

lated through the use of voltage transformers.

It is absolutely necessary to connect

the PEN conductor N.

Installation location

The UMG507 is intended for permanent in-

stallation in low and medium-voltage switch-

gear. It can be installed in any position.

Protective conductor

A protective conductor according to the valid

safety regulations must be connected at the

screw provided on the rear of the device

before the remaining connections with the

device can be made.

Supply voltage

An operating voltage is required to run the

UMG507. The type and strength of the operat-

ing voltage required for the UMG507 is noted

on the rating plate.

230V Standard version

120V Special version

63V Special version

Higher voltages between the terminals 31/32

and earth (PE) can severely damage the

UMG507. In order to prevent an overvoltage

the operating voltage should be earthed.

The operating voltage is connected at ter-

minals 31 and 32. A maximum voltage of

300VAC may occur between the terminals 31

and 32 (operating voltage) and earth (PE).

Attention!

- The wiring cables for the operating voltage

must be suitable for nominal voltages up to

300VAC to earth.

- The operating voltage must be fused. The

fuse must lie within the range from 2A to 10A.

- The building installation must include a

switch or circuit-breaker for the operating

voltage.

- The switch must be installed close to the

device and be easy for the user to reach.

- The switch must be labelled as a discon-

necting device for this device.

- Before applying the operating voltage ensure

that the voltage and frequency comply to the

values given on the rating plate!

- The device may only be run with an earthed

housing!

- Conductors with soldered individual wires

are not suitable for connections at screw-

type terminals!

-The pluggable screw terminals may only be

plugged in when no voltage is applied.

- Only pluggable screw terminals with the

same number of poles and the same type

(with/without threaded connection) may be

connected with each other.

Voltages which lie above the permis-

sible voltage range can severely dam-

age the device.

Connection options

The UMG507 can measure in systems with

N and even in systems without N through

two voltage transformers. Measurement in

systems with L1/L2/L3 and N (PEN) is called

four-wire measurement here. Measurement

in systems with L1/L2/L3 but without N is

called three-wire measurement.

The UMG507 is preset in the factory for mea-

surement in systems with N (four-wire mea-

surement).

Voltage measurement

The UMG507 is suitable for measuring alter-

nating voltages of up to 500VAC to earth and

870VAC phase-to-phase. The wiring cables

for the measured voltages must be suitabel for

voltages up to 500VAC to earth and 870VAC

phase-to-phase.

Attention!

The UMG507 is not suitable for mea-

surement of direct voltages.

Voltages over 500VAC to earth must

be connected through a voltage trans-

former .

The supply conductors for voltage

measurement in UMG507 must be

protected by an overcurrent protective

device.
