PXIe-4135 Safety Guidelines for System Operation

Caution  

Hazardous voltages of up to the maximum voltage of the PXIe-4135 may appear at the output terminals if the safety interlock terminal is closed. Open the safety interlock terminal when the output connections are accessible. With the safety interlock terminal open, the output voltage level/limit is limited to ±40 V DC, and protection will be triggered if the voltage measured between the device HI and LO terminals exceeds ±(42 Vpk ±0.4 V).

Caution  

Do not apply voltage to the safety interlock connector inputs. The interlock connector is designed to accept passive, normally open contact closure connections only.

To ensure a system containing the PXIe-4135 is safe for operators, components, or conductors, take the following safety precautions:

• Ensure proper warnings and signage exist for workers in the area of operation.
• Provide training to all system operators so that they understand the potential hazards and how to protect themselves.
• Inspect connectors, cables, switches, and any test probes for any wear or cracking before each use.
• Before touching any of the connections to the high terminal or high sense on the PXIe-4135, discharge all components connected to the measurement path. Verify with a DMM before interaction with connections.
