Mounting : DIN Rail 35mm Mounting or screw mounting
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.
3.
The auxiliary power requires isolation voltage
≥
2000VAC, DC current
output ripple
＜
10mV.
4.
Multiple transducers can share with one set auxiliary power together., and
the wire shared between the transducers and power should be short. It's
better to connect each transducer to the auxiliary power individually.
5.
Wiring in terms of the terminal identification drawing strictly.
6.
