y1 Installation and commissioning instruction
If the content is incomplete or damaged, please contact your source of
supply. Store, use and transport the meter such, that it is protected from
moisture, dirt and damage.
Important notes
This instruction is part of the documentation. All versions of the LZQJ-
XC are described in this instruction. Therefore characteristic features
may be described, which are not valid for your device.
For further information about the LZQJ-XC refer to the product
manual. Pay attention to all component accompanying docu-
ments when operating the LZQJ-XC.
Target group
This instruction is intended for technicians who are responsible for
installation, connection and maintenance of the device. The devices
have to be installed and put into operation only by qualied electricians
in accordance with generally accepted rules of technology and the
regulations, which are relevant for the installation of telecommunications
equipment and end devices.
Intended use
The meter has to be used for measuring electrical energy only and has
to operate within the specied values (refer to nameplate).
Maintenance and warranty information
The devices are maintenance-free. In case of damage (e. g. due to
transportation, storage) no repairs may be carried out independently.
If a defect is caused by external inuences (e.g. lightning, water, re,
extreme temperatures and weather conditions) or by incorrect or negli-
gent use or handling, the warranty claim and Declaration of Conformity
become invalid. The same applies if seals are broken.
Only authorised personnel are allowed to break the sealing!

Care and disposal instructions
DANGER!
Contact with live parts is dangerous to life!
Before the housing of the meter is cleaned, all conductors that the
meter is connected to must be de-energised.
Clean the housing using a dry cloth. Do not use chemical cleaning
agents!
The following table lists the components and how to handle them at the
end of their life cycle:
Komponents Waste collection and disposal
PCB‘s Electronic waste: dispose in accordance with local
regulations
LED‘s,
LC-display

indicated by a ashing R. When this symbol is continuously active,
the meter receives a ripple control signal.
7. The DCF status symbol shows the current status of the DCF77
antenna:
No symbol no reception
Symbol ashes reception, but the RTC is not yet
synchronised with the DCF77 receiver
Symbol continuous-
ly active
reception, but the RTC has been
synchronised with the DCF77 receiver
8. The symbol for setting/parameterisation is active when values are
changed in the set mode.

11
9. The symbol for the data read-out appears when data is sent to the
meter or when the meter sends data to the PC.
10. The symbol for the clock control shows if the tari󰀨 control of the
meter is controlled by the internal clock.

Installation and commissioning
Meter of the LZQJ-XC series are
suitable for wall mounting according to
DIN 43857-2.
When connecting the meter, observe
the appropriate wiring diagram, which
you can nd inside the terminal cover
and as a part of the delivery docu-
ments. Please note also the information
regarding the installation check register.
DANGER!
Contact with live parts is dangerous to life!
When installing or changing the meter, the conductor to which the
meter is connected must be de-energized.
yRemove the relevant back-up fuses and store them in such a way that
other people cannot ret the back-up fuses unnoticed.
yIf you use selective circuit breakers for disconnection from the mains,
secure them against being switched on again unnoticed.
yBefore a meter is installed, the consequences of activating the electrical
system on immediate dangers to the life and health of persons as well
as economic damage must be checked.
yTo avoid immediate dangers and damage, suitable countermeasures
must be taken prior to activation in order to prevent resulting interfer-
ence.
yDo not use the internal cut-o󰀨 relay as a switch-disconnector to discon-
nect electrical installations from the mains.
yOnly use the dedicated screw terminals for installation and connection
of the meter.

13
DANGER!
Contact with live parts is dangerous to life!
S0-inputs are not potential-free. The S0-inputs are, depending on the
voltage version, internally electrical connected to the measurement
connections or to the auxiliary voltage and therefore potential carrying.
yObserve the device-specic wiring diagram inside the terminal
cover.
DANGER!
Risk of danger to life due to electric arc and electric shock!
The voltage taps are not secured internally and directly connected to
the measuring-circuit voltage.
ySecure external devices, which are operated via the voltage taps
of the meter, with a back-up fuse of. ≤ 0,5 A in accordance with
current technical guidelines.
DANGER!
Risk of danger to life due to electric arc and electric shock!
The in- and outputs of the additonal terminals including the external
supply inputs are not secured internally
ySecure the inputs/external supply inputs with a back-up fuse of
≤ 0,5 A according to current technical guidelines.
ySecure the outputs in accordance with the power specications on
the name plate of the meter and in accordance with the applicable
technical regulations.
NOTICE!
Damage of the terminals due to excessive torque!
The appropriate torque depends on the type of the connection line
and on the maximum current.
yTighten the terminals with the required torque according to
EN 60999-1.

14
a) Transformer connected meter
DANGER!
Contact with live parts is dangerous to life!
yThe voltage taps are not fused within the meter and are directly
connected to the mains potential.
yProtect meters with a transformer connection in the voltage circuit
with a back-up fuse of ≤ 6 A.
yLoad the voltage taps with 0.5 A max.

DANGER!
Risk of danger to life due to high voltage when current transform-
ers are interrupted!
The high voltage on the interrupted current transformer at the trans-
former connected meter is extremely dangerous and destroys the
current transformer.
yShort-circuit the secondary circuits of the current transformer at the
testing terminals before disconnecting the current path.

DANGER!
Danger to life due to excess voltages on the terminals of the
current paths!
The voltages on the terminals of the current paths must not be higher
than the rated voltages of the voltage circuits and not be higher than
300 V towards N. Excess voltages can lead to res or electric shock.
yUse the meter only with suitable current transformers to avoid
exceeding the voltage limits. If necessary, the secondary side of the
transformers must be earthed.

Terminal cover
To prevent unauthorized access to the terminals, the terminal cover is
mounted with sealing screws, which you can secure with seals.
NOTICE!
Property damage due to excessive torque!
yTighten the sealing screws with a torque of 0,5 Nm.
Readout battery (optional)
The exchangable readout battery enables the reading of the display and
the readout of the meter via the optical data interface D0 when the
meter is not connected to the main voltage. Furthermore the battery
bu󰀨ers the real-time clock. Therefore a Lithium battery (CR-P2, 6 V) is
used.
CAUTION!
Danger of explosion due to improper handling of the exchangea-
ble battery!
yOnly authorised personnel are permitted to insert or replace the
battery. Batteries may leak or ignite.
yDo not short-circuit, damage, heat or open force batteries.
yDispose of the battery in the original packaging or insulate the
terminals of used batteries.
At delivery the battery function is inactive. To activate the function,
open the module cover. Pull out the battery holder. Remove the battery
from the holder, turn the battery and reinsert it. Then insert the battery
holder into the battery compartment (contacts facing left!) and close the
moldule cover.
