4 EVM Setup and Operation

Safety: This evaluation module is not encapsulated and there are accessible voltages that are greater than 50 VDC.

Isolation Input Transformer: A suitably rated 1:1 isolation transformer shall be used on the input(s) to this EVM and be constructed in a manner in which the primary winding(s) are separated from the secondary winding(s) by reinforced insulation, double insulation, or a screen connected to the protective conductor terminal.

WARNING:

  • If you are not trained in the proper safety of handling and testing power electronics please do not test this evaluation module.
  • While the EVM is energized, never touch the EVM or its electrical circuits, as they could be at high voltages capable of causing electrical shock hazard.
  • Caution Hot surface. Contact may cause burns. Do not touch!
  • Read this user's guide thoroughly before making test.
