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!

2.4 Installation on top-hat rail according to EN 60715

Latch the mounting clip on the reverse of the device to the top-hat rail so that a safe and secure fit is

ensured.

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.
