Prologue
This manual describes all designs of the meter. Please note that the meters can be
designed differently regarding, for example, configuration, interfaces in-/outputs etc. It is
therefore possible that meter features are described here which do not apply to the
meter(s) used by you.
1.1
Saf ety tips
The meters are to be used exclusively for measuring electrical energy and must only be
operated within the specified technical data (see also nameplate).
When installing or changing the meter, the conductor to which the meter is connected
must be de-energised. Only the intended screw terminals may be used for this. Contact
to parts under voltage is e
ex tre me ly d an ge ro us .
Therefore the relevant back-up fuse is
to be removed and stored so that other people cannot insert this unnoticed.
With incorrect meter installation the S0-inputs can lead to line voltage.
At te n tio n : Da ng e r !
The local standards, guidelines, regulations and instructions are to be obeyed.
Only authorized personnel are permitted to install the electricity meters.
1.2
M ai n te n an ce a nd gua ra nt ee t i ps
The meter is maintenance-free. With damages (e.g. due to transportation, storing) no
repairs may be carried out independently.
As soon as the meter is opened, the guarantee claims cease. The same applies in case
the defect can be traced back to external influences (e.g. lightning, water, fire, extreme
temperatures and weather conditions, improper or negligent use or treatment).

Mou ntin g the m et er
The meter is designed for mounting on DIN-rails TH 35-7.5 accord. to DIN 60715.

2.2
Ins t al lati on
When installing the meter, please pay careful attention to the connection diagram which
can be found on the inside of the terminal cover. On page 8 you can find examples of
connection diagrams.
The meter must be secured with an overcurrent protection device of 63 A.
.
The control
input is to be protected with a back-up fuse of 0,5 A.
In order to protect the meter from unauthorized access, the meter can be equipped with
a seal at the sealing eye (see page 11).
The current and voltage supply inputs can be found on the top of the meter.
The current outputs, the optional electrical interface, the control input and the impulse
output can be found on the bottom of the meter.

Note
:
:
Please ensure when installing the meter that, after threading the connecting leads,
the screws are tightened to the correct torque according to EN 60999 in order to
guarantee a safe contact. The torque depends on the type of the connecting leads
and the maximum current.

In the following you can find examples of some connection diagrams. When connecting a
meter pay attention to the connection diagram which can be found inside the terminal
cover or in the delivery documents.

In the following all design variants of the meter are described.
It is therefore possible that meter features are described which do not apply to the meter
used by you.
The meter is a digital 1- or 2- tariff meter for measuring positive active energy in 2- and
4-wire networks.
Tariff switching takes place via an external control input. The meters are principally used
for energy data registration in the industry and building installation, switching stations
and the field of energy supply. The compact design of this meter allows „space saving“
mounting (only 4 pitch wide).
The meter has a 7-digit LC-display. The energy consumption values are displayed with 6
integer digits and 1 decimal digit.
They can, however, also be given out via a pulse output (max. 27 V DC, 27 mA) and/or
via an electrical interface (M-Bus, according to EN 13757-2, -3). The pulse constant
(100 Imp/kWh) and the pulse length (100 ms) are fixed.
The meter corresponds to the accuracy class B according to EN 50470-1, -3.
