Step 1: Immobilize one side of product‘s mounting trough to the DIN mounting rail;
Step 2: Pull out the spring clasp;
Step 3: Place whole mounting trough to the DIN mounting rail properly;
Step 4: Release spring clasp to make sure the installation.
2.
The product has calibrated before out of factory. After correctly wiring, it can be
powered and used immediately. But for further precise signal sampling, user needs to
warm-up the product for 3 minutes before use.
The auxiliary power requires isolation voltage≥2000V
AC
, DC current output ripple
＜
10mV, and multiple converters can share with one set auxiliary power together.
3.
The Maximum volume of line for the sensor terminal is 2.5mm
2
; the insulation layer of
the line should be peeled off about 8mm
～
10mm and tightly twisted to connect with the
sensor terminals.
4.
For the less than 10A AC current measurement, it may adopt ampere-turn method for
input and for this time, the resolution of the sensor increases and measuring range
narrows, but other technical index may not be affected.
5.
Basic testing method for accuracy
(1)
According to the terminal definition table to connect the testing circuit;
(2)
The testing must to be done by under the following conditions
；
Auxiliary power: DC +9V
～
+36V
，
ripple
≤
5mV
Ambient temperature: 25
℃±
2
℃
Relative humidity: RH(45
～

％
Accuracy for Signal Power Source instrument: 0.05
(3)
Warming up the sensor for 3 minutes
(4)
Using output monitoring meter V1 to measuring the output of signal power
source instrument, set any input value which is within the measuring range of
the sensor Ir. (e.g. if input value is 50A, the output is
0V～5V
