Schneider inverter debugging steps and brief description
Commissioning process of the Schneider 61 series
1. Preparations
1. Measure insulation. Connect the power supply side (R.S.T) and the motor side (U.V.W) of the inverter
Disconnect the cable, insulate the cable with a 500 megaohm or 1000 megaohm shake meter, and if it meets the requirements, restore it.

The difference between Schneider UPS and EPS power supply
1. Different safety standards
UPS is mainly used to protect users' equipment or business from economic loss, and its product technical certification mainly includes Thiel certification, CQC certification, etc. The development of EPS power supply stems from the sudden failure of the power grid, in order to ensure the power safety and fire linkage needs, it can be supplied immediately.
