5.2.- Starting the
QNA-P/PV
analyzer
Please check following points before switching on the analyzer:
1) Mains supply voltage:
Voltage: 100-240 V AC (QNA-P)
Voltage: 100-400 ± 30% V c.a (QNA-PV).
Frequency: 50... 60 Hz.
2) Ground terminal: The ground terminal of the analyzer must be connected to earth.
If it is not connected some of the protective parts may not work properly.
3) Maximum voltage in the voltage measurement circuit: 500 V C between phase
and common:
4-wire: 500 V AC line-to-neutral. / 866 V AC line-to-line.
3-wire: 500 V AC line-to-line.
4) Maximum voltage in the Earth measurement circuit: 500 V AC between Neutral
Earth.
5) Maximum permissible current :
Depends of the clamp In / 2 V c.a.
6) Consumption: 16 VA – 8 W
7) Operating conditions:
•
Operating temperature range: 0ºC to 50ºC.
•
Storage temperature: -20ºC to 70ºC
•
Operating humidity: 0% to 90 % RH.
8) Safety: Designed to meet protection class III according to EN 61010.
Points to check during the installation process:
9) Check that the ground terminal of
QNA-P/PV
is connected to earth to avoid any
possible interferences to the analyzer. If this ground terminal is not connected,
then the effectiveness of the
QNA-P/PV
protection elements may be reduced.
10) Check power readouts and their sign (check current measurement transformer
polarity).
10) Verify the
QNA-P/PV
setup.
