Working voltage up to max. 760 V AC absolute value
at voltage measurement inputs.
TNV1 circuits, some of which interconnected:
digital inputs and outputs, optional temperature inputs,
optional Modbus interface.
Casing design
Flammability rating UL 94 V-0 according to casing manufacturer
Impact resistance IK06 as per EN 61010-1:2011-07, 8.2.2
Service life
At +25 °C ambient temperature 15 years
EMC
EMC as per EN 61326-1
EN 61000-4-2, electrostatic discharge: air 8 kV and contact 6 kV with
horizontal and vertical coupling plane
EN 61000-4-3, radiated immunity (EMS) 80 MHz – 1 GHz, horizontal and
vertical, level 10 V/m = industrial environment radiation, Class A
Hardware version V1.0:
EN 55022A EMI 30 MHz – 1 GHz = industrial environment, Class A
Being a Class A device, this version can cause radio interference in resi-
dential areas. In this case, users may be called upon to take appropriate
remedial measures at their own expense.
From hardware version V1.2:
EN 55022A EMI 30 MHz – 1 GHz = office and residential area, Class B
EN 61000-4-6, immunity to conducted disturbances, level 10 V RMS,
150 kHz – 80 MHz

PQC xxxxxxx-3x:
EN 55022A EMI 30 MHz – 1 GHz = office and residential area, Class A
EN 61000-4-4, burst immunity, 1 kV capacitive coupling, 2 kV injection
into power supply cable and voltage measurement inputs
EN 61000-4-5 surge immunity, 6 kV injection into power supply cable
and voltage measurement inputs
1 The standard radio-frequency field test as per EN 61000-4-6 (EMC immunity) calls for amplitude modu-
lation at a modulation frequency of 1 kHz. However, this frequency lies within the measurement range of
the instrument in its intended use (20th harmonic of 50 Hz = 1 kHz). It is therefore to be expected that the
measuring circuit clearly respond to the standard test. For this reason, the radio-frequency field test can
only be carried out without amplitude modulation.
