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 need to warm-up the product for 3
minutes before use.
a)
the auxiliary power requires isolation voltage
