1 General Description
The UMD 701 is specially designed for monitoring of energy and power quality in advanced power systems and
smart grids. It is intended to be used mostly for DIN rail mounting. This display-less design with multiple
communication options is suitable for a wide spectrum of automation tasks in modern buildings, distributed
power generation, remote supervision of the infrastructure and also remote load management. Absence of local
panel controls (display and keyboard) limits possibilities for hostile user interaction. To protect the actual
setup and collected data each instrument can be locked by a custom pin. Inputs and outputs can be custum
programmed for basic local control applications. It uses standard RS-485 serial line for communication with
remote control systems. Optionally it can be equipped with other communication peripherals such as secondary
RS-485 or M-Bus communication line, or USB, WiFi and Ethernet interface.
It is equipped with one voltage input and two, four or eight current inputs. The instrument can be also
supplied with for current transformers with X/100 mA ratio, for special Hall probes (to measure DC or AC+DC
currents) with ➧4 V output, or Sxxx and Pxxx option for external through-hole or clamp-on current sensors for
direct measuring up to 2400 A nominal current according to the type of the current transformer.
Warning !
The X/100mA, Sxxx and Pxxx, X/➧4 V options are specially designed to be used only in
combination with provided external current sensors which are supported with the respective option.
The UMD 701 is available in several configurations according to the customer requirements1. See the ordering
scheme on figure 1.

If the analyzer or its accessories appear to be impaired or not functioning properly, do not use it and send
it in for repair.
2.2 Installation of the instrument
Natural air circulation should be provided inside the distribution board cabinet, and in the instrument’s neighborhood. Especially underneath the instrument, no other instrumentation that is source of heat should be installed
or the temperature value measured may be influenced. A connection

The UMD 701 is primarily intended for DIN-rail mounting. Dimensions of the instrument are on figure 2.
There are also positions marked with dash dot lines of holes for wall-mounting with three screws.
Figure 2: Dimensions of the UMD 701 analyzer.
2.2.1 Supply voltage
Power supply voltage (options in ch. 3) must be connected to the terminals X1 and X2 via a circuit breaking
device (power switch – see installation diagram on figure 3). It has to be located left to the instrument and
reachable by the operator. The circuit breaking device must be identified as the equipment power disconnection
switch. A circuit breaker of the nominal value 1 A is a convenient circuit breaking device. Its function and
position has to be clearly identified (symbols
galvanically isolated from internal circuits.
2.2.2 Measured voltage
The measured voltage is connected to the terminal L1. Connect the neutral wire to the terminal N. Voltage
measurement inputs are connected with internal circuits over high impedance.
It is suitable to protect the measured voltage lines for example with 1A fuses of the required rating. Measured
voltages can also be connected via instrument voltage transformers. A connection cable maximum cross section

with low voltage supply voltage (possible DC, AC including battery backed UPS setups); with supply from
measured network. Option E for Ethernet port remote communication, option U for local USB communication
port (all instruments provide RS485 serial line).
2.2.3 Measured currents
For proper current measuring the current sensors must be installed with correct orientation and polarity. Figure 3
illustrates such a connection of various current transformers in LV network. Intended direction of power flow
is from left (source) to right (load). It is highly recommended to verify correctness of wiring and polarity of
currents with phasor diagram in Actual Data window ot the EnVis.Daq application.
The current inputs are directly connected with internal circuits. Inputs I1,I2,..,I8 and C are connected through
shunt resistors (or divider in case of X/4V option). A connection cable maximum cross section area is 2.5
Warning !: Current inputs can not be used for dirrect current measurement. Connection of
unsupported type of current transformer such as the common type with 5A or 1A secondary to
an instrument is strictly forbidden! The instrument can be seriously damaged!
Warning !: Do not connect the current input signals with neither ground nor other potential!
Otherwise, measurement accuracy can be affected or the instrument can be damaged!
Always use only correctly rated measurement current transformers (such as ➧X mA or ➧4V) which were
originally supplied with the actual instrument.
2.2.4 Communication peripherals

2.4 Energy meter readings
UMD 701 has an embedded four-quadrant energy meter with automatic meter reading functions and multiple
programmable tariffs (Time-of-Use, TOU). The instrument registers active energy (EP, EP+, EP-) and reactive
energy (EQL, EQC or EQC+, EQC-, EQL+, EQL-). According to the configuration of meter readings are
shuffled to the respective tariffs. It automatically provides summaries per phase. For star connections and single
phase measurements it can also register energy for each phase separately.
Meter data readings can be downloaded and analyzed in EnVis or via the standard ModBus protool in any
other system.
