duct and therefore eliminates the warranty for covering

any potential damage resulting from this.

This device is to be operated and maintained exclusively

by specialized personnel.

cIf the device is not operated according to

the operating manual, protection is no lon-

ger ensured and danger can come from

the device.

mConductors made from single wires must

be ﬁtted with wire-end ferrules.

mOnly pluggable screw terminals with

the same number of poles and the

same type of construction are permitted

to be connected together.

Specialized personnel are persons, that based on their

respective training and experience, are qualiﬁed to re-

cognize risks and prevent potential dangers that can be

caused by the operation or maintenance of the device.

Additional legal and safety regulations required for

the respective application are to be following during the

use of the device.

UMG 96RM-EL

Inspection on receipt

The prerequisites of faultless, safe operation of this de-

vice are proper transport and proper storage, set-up and

assembly, as well as careful operation and maintenance.

If it can be assumed that risk-free operation is no longer

possible, the unit must be immediately put out of opera-

tion and secured against being put back into operation

again.

The packing and unpacking must be carried out with

the customary care without the use of force and only

using suitable tools. The devices should be visually che-

cked for ﬂawless mechanical condition.

It can be assumed that risk-free operation is no longer

possible if the device, for example,

• has visible damage

• no longer works despite the mains power supply

being intact

• has been exposed to long-term adverse conditions

(e.g. storage outside the permissible climate limits wi-

thout being adapted to the room climate, condensa-

tion etc.) or rough handling during transportation (e.g.

fall from a height, even if there is no visible external

damage etc.)

• Please check the delivered items for completeness

before you start installing the device.

CAll screw-type terminals included in

delivery are attached to the device.

Concerning these operating instructions

These operating instructions are a part of the product.

• Read the operating instructions before using the de-

vice.

• Keep the operating instructions throughout the enti-

re service life of the product and have them readily

available for reference.

• Pass the operating instructions on to each subse-

quent owner or user of the product.

UMG 96RM-EL

Product description

Intended use

The UMG 96RM-EL is provided for the measurement

and calculation of electrical parameters such as voltage,

current, power, energy, harmonics, etc. for building

installations, to distributors, circuit breakers and busbar

trunking systems.

The UMG 96RM-EL is suitable for installation in

permanent, weatherproof switchboards. Conducting

switchboards must be earthed. It can be mounted in any

position.

Measurement voltages and measurement currents must

originate from the same grid.

The measurement results can be displayed and can

be read and processed over the Ethernet interface.

The voltage measurement inputs are designed

for measuring in low voltage grids in which nominal

voltages up to 300V phase can occur in countercurrent

with ground and overvoltages of overvoltage category

III.

The UMG 96RM-EL current measurement inputs are

connected via external ../1A or ../5A current transformers.

Measurements in medium and high voltage systems

generally use current and voltage transformers.

The UMG 96RM-EL can be used in residential and

industrial areas.

Device characteristics

• Installation depth: 45 mm

• Supply voltage:

20V - 250V (45..65Hz) or DC 20V - 300V

• Frequency range: 45-65 Hz

Device functions

• 3 voltage measurements, 300 V

• 3 current measurements

(via current transformer)

• Ethernet interface

UMG 96RM-EL

Measuring method

The UMG 96RM-EL measures uninterrupted and

calculates all root mean squares over a 10/12-period

interval (200ms). The UMG 96RM-EL measures the true

root mean square (TRMS) of the voltages and currents

applied to the measuring inputs.

Operating concept

There are several ways to program the UMG 96RM-EL

and retrieve measured values.

• Directly on the device using two buttons.

• Via the programming software of the GridVis.

These operating instructions only describe the operation

of the UMG 96RM-EL using the 2 buttons.

The programming software of the GridVis has its own

“online help”.

GridVis network analysis software

The UMG 96RM-EL can be programmed and read with

the GridVis network analysis software which is part of the

scope of delivery. For this a PC must be connected to

the UMG 96RM-EL via Ethernet.

Characteristics of GridVis

• Programming the UMG 96RM-EL

• Graphic representation of measured values
