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)
When measuring dc voltage exceeds 1000volts, the circuit needs adding a resistor
to divide the input dc voltage. The resistor is provided by Weibo Electronic, and
only for each type of transducers special use only.
