1Safety
Caution! Never work when voltage is applied.
This poses a life-threatening risk! Never use the device if there is obvious
damage! Use only by trained specialist personnel!
1.1 Intended use
The TELE NA003 serves as grid and system protection for supplying cogeneration units, wind power stations,
hydroelectric power plants, and photovoltaic systems.
In the event of a power failure or a fault in the grid of the energy supply company, private small power
plants must immediately be isolated from the public grid to prevent accidental infeed. For one, maintenance
personnel could be endangered without immediate grid separation, and secondly, consumers could be
exposed to impermissible voltages and frequencies.
In case the grid operator requires threshold values that deviate from the standards, it is possible in part to
set some of the threshold values outside of the standard defined range.
Outside of this range the device is no longer in compliance with standards and the corresponding
certificates lose their validity. This status is shown on the display by the identifier "ncnf." Settings outside of
this range are therefore within the operator's scope of responsibility and/or the acceptance authority of the
system.
1.2 Safety advice
This device was built and tested in accordance with recognized technical safety regulations. However,
incorrect use can still result in danger for both persons and machine.
Only use this device as intended, in a technical safe condition, and in compliance with the applicable rules
and regulations for accident prevention valid at the usage location.
•Fix all faults that could impair the safety immediately.
•Do not make any unauthorized changes and only use spare parts and additional devices that are
sold or expressly recommended by the manufacturer of the device.
•The device may no longer be used in case of obvious damage.
•Country-specific standards and guidelines are to be observed.
•The NA003 can be protected against authorized changes after commissioning via password
protection or sealing. One of the protection mechanisms named above must be applied if this is
required in the respective country-specific standard or guidelines.

Subject to modifications and errors Page 6 of 71 2019-06-26 edition
1.3 Qualified electrician
A qualified electrician can independently recognize and prevent dangers from electricity. Requirements for
this are:
•Knowledge of electrical engineering
•Experience in electrical work
•Knowledge and work experience with the corresponding system or similar systems (system type)
•Knowledge of the hazards and countermeasures
•The ability to recognize whether safety is provided during the performance of work
Qualified electricians are specially trained and know the relevant standards and regulations for the work
environment in which they are active. The regulations of the corresponding country apply.

2.2 Back-up fuse of the supply voltage
The supply and measuring voltages of all system components are to be secured with back-up fuses. The
back-up fuses are to be dimensioned according to the conductor cross-section used.
We recommend securing the output relay against the danger of short-circuit with a 5A fast acting fuse!

3.2 Functional description
Depending on the configuration selected, the device can handle several monitoring functions at the same
time.
After exceeding a threshold value, the device switches off after a turn-off delay that is defined especially for
each threshold value. When the test function or the remote shutdown is activated, the device switches off
immediately. Only once all monitored parameters are within the permissible limits and the remote
shutdown deactivated does the device switch back on after a defined turn-on time.
If not specified otherwise, the nominal voltage is 230 V / 400 V and the nominal frequency 50 Hz.

3.2.1 Innovations with regard to VDE-AR-N 4105
For the 3 new parameter sets of VDE-AR-N 4105 (3.3.3-5), the following applies for the commissioning:
When commissioning, make sure that only one coupling switch (on R1) is used. 3.3.5. for inverters is an
exception here - 2 coupling switches (on R1 and R2) must still be used.
Furthermore, the feedback contact(s) must be connected to the digital inputs I1(2)- ┴provided for this
purpose. Finally, parameter 3.099 determines whether the feedback contact(s) are normally closed (n.c.) or
normally open (n.o.).
An Error C (Contact) appears on the display if this has not been taken into account. NA003 must not switch
on the output relays R1(2) for VDE-AR-N 4105 during error C as long as the feedback contacts are not
correctly connected and parameterized.
Contact Error-Reset:
If UN3x400V AC is correctly connected, a reset can only be carried out by pressing the Esc (level 1.010) or Ent
(level 1.050) key. The contact error is then cleared and the output relays R1/2) energize after the switch-on
time has elapsed.
An existing contact error can also be reported to the generation system via R3.
In this context, we would like to refer to Chapter 3.9 Test function (Determination of the tripping time of the
coupling switch).
Password protection:
With regard to VDE-AR-N 4105, the devices are supplied with fixed password protection. The password is
"4105". The commissioning engineer is requested to change the password immediately for safety reasons
(see 5.2.5).

3.4.1 Voltage monitoring
Line to line Overvoltage 1
Overvoltage 2
All 3 phase to phase voltages are monitored according to the
set overvoltage thresholds!

L3+N) coupling mode!
Line to line Undervoltage 1
Undervoltage 2
All 3 phase to phase voltages are monitored according to the
undervoltage thresholds set!
After exceeding the switching threshold, the device triggers
after the set trigger delay toff.
Can be deactivated in 2-phase (L+N) as well as 4-phase (L1, L2-
L3+N) coupling mode!
Line to Neutral
Overvoltage 1
Overvoltage 2
All 3 phase-to-neutral voltages are monitored according to the
overvoltage thresholds set!

after the set trigger delay toff.
Exception: In 2-phase (L+N) coupling mode, only one
overvoltage measurement takes place between L1 and N!
Can be deactivated in 3-phase (L1, L2, L3) coupling mode!
Line to Neutral
Undervoltage 1
Undervoltage 2
All 3 phase-to-neutral voltages are monitored according to the
undervoltage thresholds set! After exceeding the switching
threshold, the device triggers after the set trigger delay toff.
Exception: In 2-phase (L+N) coupling mode, only one
overvoltage measurement takes place between L1 and N!
Can be deactivated in 3-phase (L1, L2, L3) coupling mode!
Average
Overvoltage
The 10-minutes average generated is monitored according to
the switching thresholds set for the slow voltage increase
protection!
After exceeding the switching threshold, the device triggers
after the set trigger delay toff.
In 2-phase coupling mode: L-N
In 3-phase coupling mode: L1-L2-L3
In 4-phase coupling mode: L1-N; L2-N; L3-N

Underfrequency 1
Underfrequency 2
Underfrequency 3
Underfrequency 4
The frequencies of the 3 phase-to-neutral voltages are
monitored according to the under-frequency thresholds
set.
Exception: in 2-wire mode only U L1-N
Random over frequency
The frequency of the 3 phase-to-neutral voltages are
monitored according to the parameters set (random max.
frequency).
Exception: in 2-wire mode only U L1-N
Frequency monitoring undervoltage LL
Frequency monitoring undervoltage LN
Depending on the mode (2-, 3-, 4-wire,) falling below the
set threshold leads to the deactivation of the frequency
comparators.
RoCoF
The frequency change rates of the 3 phase-to-neutral
voltages are monitored according to the parameters set.
Exception: in 2-wire mode only U L1-N
