The same applies where a defect is caused by external factors (e.g.
lightning, water, re, extreme temperatures and weather conditions),
or by improper or careless use or handling.
The seals may only be broken by authorised personnel.
Care and disposal information
DANGER!
Risk of fatal injury in case of contact with live parts!
Before the housing of the meter is cleaned, all conductors that the

Basic safety instructions
Please adhere to the following basic safety instructions:
yRead the enclosed instructions and information.
yObserve the warnings on the device and in the documents.
yAlways be aware of safety issues and hazards when working on the
device.
yThe customary local occupational health and safety regulations for
electrical installations must be observed during assembly, installation
and removal of the device.
yMake sure that the installation and operating location of the device
meets the specications in the technical data.
yBefore assembly, check the devices for any transport damage or
other externally visible damage.
yOnly use the device if it is in a technically awless state, and solely in
line with its intended use.
yThe connection cables used to connect a meter must be selected to
match the maximum load of the meter and the installation environ-
ment in terms of type, cross-section, voltage and temperature.
yAttach ferrules to exible wires.
yObserve the maintenance and warranty instructions.
yIf the mains power fails and then returns, there is no need to do
anything to the meter.

Display
1. The operation display shows the energy direction that is currently
being measured by the meter (supply/draw of active power, inductive/
capacitive reactive power). If a load current is owing, the energy
direction arrow indicates which quadrant is being used for the
measurement, e.g.:
1st quadrant +P/+Q 3rd quadrant –P/–Q
2nd quadrant –P/+Q 4th Quadrant +P/–Q
2. The battery status indicator shows the residual capacity of the power
reserve of the real time clock. The following displays are possible:
= Full voltage, real time clock is buered during an absence
of voltage.
= Discharged, real time clock can no longer be buered.
The battery status display appears only for devices with
a battery-buered real time clock.
3. The communication display lights up permanently when one of
the data interfaces (optical or electrical) is communicating with the
meter. The communication display ashes when parametrisation
mode is active.
On an XC-Rack with an LMN interface, this display lights up at
irregular intervals as internal communications take place to provide
the data for collection by an SMGW.

4. The phase display indicates when individual phase voltages are
applied. All 3 symbols ash on and o when the rotating eld is
wrong.
5. The unit shown matches the type of energy being measured or
the measured value displayed.
6. The additional cursor eld displays the operating states for
the meter. The arrows indicate whether an installation error was
registered or if the power threshold was exceeded.
INST The cursor is active if an entry has been registered in
the installation error control tab.
PWR The cursor is active if the dened power threshold in
the meter was exceeded.
7. The standard cursor eld displays the operating states for the
meter. The arrows indicate which tari and maximum meter are
active, and how the meter is being controlled (clock or ripple control
receiver).
T1 - T4 Tari information for energy. All activatable tari indexes
are denoted on the name plate.
M1 - M4 Tari information for power. All activatable tari indexes
are denoted on the name plate.
RCR The cursor ashes on and o when the internal ripple
control receiver is active and ready to receive. The corre-
sponding cursor is permanently active when the internal
ripple control receiver receives a telegram.
RL The cursor ashes on and o as long as a resetting lock
is active.
CLOCK The cursor is active when the internal device clock
actuates the tari meter.
SET The corresponding cursor is active when the meter is in
the Set mode.
8. The value area displays the measured values.
9. The OBIS code area denes the measured values according to the
OBIS key. The display is able to display the long OBIS key.
