Instruction of Installation and Use
1. The product has adopted structure compliance with EN50022; suitable for DIN rail
mounting NS35/7.5, NS35/15. Installation steps are as following (please reference to
dimensional drawing):
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.
a)
The auxiliary power requires isolation voltage≥2000V
AC
, DC current output ripple
＜
10mV, and multiple converters can share with one set auxiliary power together.
b)
Output signal (Iz) is designed to follow the impedance load value of 250
Ω
;
When
Resistance (R
1
) is less than
100
Ω
,
the user must add output current circuit a power
reduced resistance load R
0
to keep the summation of total impedance value is
between
100
Ω～
250
Ω
3.
