Issue Details

  • What will happen if I connect 24V DC to a chassis
  • I am powering the chassis with batteries what happens if I connect the wrong way


Some of the PXI cards that require extra power supply have the polarity protection but unfortunately the chassis do not have this connection. It is not recommend to connect incorrectly. Please confirm with the specific chassis manual
