F&F WN-723 Instructions

WN-723
Voltage indicator,
3-phase
Do not dispose of this device in the trash along with other waste! According
to the Law on Waste, electro coming from households free of charge and
can give any amount to up to that end point of collec� on, as well as to sto-
re the occasion of the purchase of new equipment (in accordance with the
principle of old-for-new, regardless of brand). Electro thrown in the trash or
abandoned in nature, pose a threat to the environment and human health.
Purpose
The WN-723 voltage indicator is designed for continuous measu-
rement and optical visualization of the voltage value in a 3-phase
network.
Functioning
The indicated voltage range for each phase is from 205÷245 V
with a reading accuracy of 2.5 V. The illumination of the LED indi-
cates voltage value described on its height. If 2 LEDs are on, the
voltage value is the average of the values described on their he-
ights. The voltage value within the tolerance (215 V to 245 V) is
indicated by the lighting of the LEDs green LEDs are lit, and other
values are indicated by the lighting of the red. Voltage equal to
or higher than 250 V is indicated by indicated by the illumination
of the highest red LED (≥). Voltage equal to or lower than 200 V
is indicated by the lighting of the lowest red LED (≤).
