PXIe-4135 Safety Guidelines for System Design and Implementation

Last Modified: January 11, 2021


Always refer to the specifications document for your device before connecting signals. Failure to observe the specified maximum signal ratings can cause shock, a fire hazard, or damage to the devices connected to the PXIe-4135. NI is not liable for any damage or injuries resulting from incorrect signal connections.

The PXIe-4135 is capable of generating hazardous voltages and working within hazardous voltage systems. It is the responsibility of the system designer, integrator, installer, maintenance personnel, and service personnel to ensure the system is safe during use.

  • Ensure operators cannot access the PXIe-4135, cables, the device under test (DUT), or any other instruments in the system while hazardous voltages are present.
  • Operator access points can include, but are not limited to, guards, gates, sliding doors, hinge doors, lids, covers, and light curtains.
  • If using a test fixture enclosure, ensure that it is properly connected to safety ground.
  • Ensure that the PXIe-4135 is properly secured to the chassis using the two front panel mounting screws.
  • Double insulate all electrical connections that are accessible by an operator. Double insulation ensures protection if one layer of insulation fails. Refer to IEC 61010-1 for specific insulation requirements.
