Meaning of the symbols used

The following pictograms are used in this

manual:

Dangerous voltage!

Danger or risk of severe injury.

Disconnect the system and device

from the power supply before starting

the work.

Important!

Please note and follow the

documentation. This symbol is

intended to warn you of possi-

ble hazards that can occur during

installation, starting up and use.

CNote.

UMG 104

Inspection on receipt

Fault free and safe use of this device requires

appropriate transport, proper storage, erection

and assembly as well as careful operation and

maintenance. If it can be assumed that safe

operation is no longer possible, the device

must be immediately taken out of service and

secured against being accidentally started

up.

The device must be unpacked and packed

with the usual care, without the use of force

and only using suitable tools. The devices

must be visually inspected for perfect

mechanical condition. Please also note and

follow the installation instructions enclosed

with the device.

It can be assumed that safe operation is no

longer possible if the device, e.g.

• has visible damage,

• no longer works, despite intact mains power

supply,

• has been exposed to unfavourable conditions

(e.g. storage outside the permissible climatic

limits without adjustment to the ambient

climate, condensation, or similar) for a lengthy

period or was exposed to unfavourable effects

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

height even if there is no visible external

damage, or similar).

Please check the scope of supply for

completeness before you start installing the

device.

All supplied options and design

versions are described on the delivery

note.

The installation and start-up instruc-

tions also describe options which do

not belong to the scope of supply.

All screw-type terminals belonging to

the scope of supply are plugged into

the device.

Notes on Use

Please read these operating instructions and

all other publications which have to be used

to work with this product (in particular for

installation, operation or maintenance).

Note and follow all safety instructions as well

as any warnings. If you do not follow the

instructions, personal injuries and/or damage

to the product could be the result.

Any unauthorised change or use of this device

which extends beyond the given mechanical,

electrical or other operating limits can cause

personal injuries and/or damage to the

product.

Any such unauthorised change is “misuse”

and/or “negligence” under the product's

warranty and therefore excludes the warranty

for cover of possible resulting injuries or

damage.

This device may be solely operated and

maintained by skilled persons.

Skilled persons are people who, on the basis

of their relevant training and experience, are

capable of identifying risks and avoiding

possible hazards which operation or

maintenance of the device can cause.

When using the device, any additional legal and

safety regulations required for the respective

use must be observed.

UMG 104

Important!

If the device is not operated according

to the instruction manual, protection

is no longer ensured and the device

can cause hazards.

Conductors made of individual wires

must be ﬁtted with wire end ferrules.

Only pluggable screw terminals with

the same number of poles (pins) and

of the same type may be plugged

together.

Product Description

Intended use

The UMG104 is intended to be used for the

measurement and calculation of electrical

variables such as voltage, current, energy,

work, harmonic components, etc. in building

installations, at distribution boards, circuit-

breakers and busbar trunking systems.

Measuring-circuit voltages and currents must

originate from the same system.

The UMG104 is permanently installed in

control cabinets or small distribution boards.

It can be installed in any position.

The measurement results can be displayed,

stored and read out via serial interfaces and

further processed.

The voltage measurement inputs are designed

for measurements in low-voltage systems in

which rated voltages up to 300 V conductor

to earth and surge voltages of overvoltage

category III can occur.

The current measurement inputs of the

UMG104 are connected via external ../1A or

../5A current transformers.

Mains failure detection

The mains failure detection takes place via the

voltage measurement inputs. The selection of

voltage measurement inputs can be conﬁgured

using the GridVis software.

Mains failure stored energy time

The UMG104 bridges the following mains

failures at the auxiliary voltage input:

Mains voltage Stored energy time

230V AC max 80ms

Measurement in medium and high-voltage

systems takes place with current and voltage

transformers. Special safety requirements

must be complied, which are not dealt with in

any greater detail here.

The UMG104 fulﬁls the test requirements for

use in industrial areas.
