throughout the complete service life of the product

and have them readily available for reference.

• Pass the operating instructions and this description

on to each subsequent owner or user of the product.

UMG 96RM-P/-CBM

Incoming inspection

The prerequisites of faultless, safe operation of this

device are proper transport and proper storage,

setup 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 operation 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

checked 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 without

being adapted to the room climate, condensation etc.)

or rough handling during transportation (e.g. fall from a

height, even if there is no visible external damage etc.)

• Please check the scope of deliverables for

completeness before you start with the installation of

the device.

UMG 96RM-P/-CBM

Product description

Proper use

The UMG 96RM is intended for the measurement and

calculation of electrical parameters such as voltage,

current, power, energy, harmonics etc. in building

installations, on distribution units, circuit breakers and

busbar trunking systems.

The UMG 96RM is suitable for integration into ﬁxed and

weatherproof switch panels. Conductive switch panels

must be earthed. Can be installed in any attitude.

Measured voltage and measured current must derive

from the same network.

The measurement results can be displayed and can be

read out and further processed via the interfaces.

The voltage measurement inputs are designed for

measurements in low voltage networks, in which rated

voltages of up to 300V relative to earth and surges in

overvoltage category III can occur.

The current measurement inputs of the UMG 96RM are

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

The measurement in medium and high voltage networks

is implemented in principle via current and voltage

transformers. The UMG 96RM can be employed both

domestically and in industry.

UMG 96RM-P/-CBM

Measuring process

The UMG 96RM measures continuously and calculates all

effective values over a 9 period interval. The UMG 96RM

measures the real effective value (TRMS) of the voltage

and current connected to the measurement inputs.

Parameterising

You can parameterise the UMG via buttons 1 and 2 or

via the RS485 or USB interface.

You can only parameterise a small portion of the functions

directly on the device via the buttons. The list of functions

can be found in table 1 of the installation instructions for

the basic device.

All functions can be parameterised via the serial

interfaces and with the GridVis programming software.

Only the RS485 interface is available on

the basic device.

Additional components that are not

included in the scope of deliverables will

be required for parameterisation via the

RS485 interface.
