3.Basic operation
3.1. Matters need attentions
Operating this module requires certain professional skills, prohibit non-professionals operate on it!
Before using it, you must study Knowledge of safe use carefully.
prohibit human body contact with L and N power lines after electrification to prevent accidents caused by
electric shock.Recommend input front-end to increase isolation.
The maximum input voltage shall not exceed 264 Vac, otherwise may occur permanent damage.
In daily maintenance, the input power should be disconnected to prevent from electric shock accidents.
