Safety Guidelines for System Design and Implementation
The PXIe-4137 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-4137, 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-4137 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.
Mechanical Detection Switch Recommendations
• Use high-reliability, fail-safe, normally open mechanical detection switches on all access points to the test fixture enclosure.
• Use two normally open switches wired in series so that a single switch failure does not compromise safety protections.
• Isolate switches so the operator cannot trigger or bypass the switches without the use of a tool.
• Ensure the switches' certifications meet your test application requirements. NI recommends UL-certified safety switches to ensure reliability.
• Install the switches in accordance with the switch manufacturer specifications.
• Test the switches periodically to ensure proper implementation and reliability.

Safety Guidelines for System Operation
Caution Hazardous voltages of up to the maximum voltage of the PXIe-4137 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 V peak ±0.4 V).
Attention Des tensions dangereuses allant jusqu'à la tension maximale du PXIe-4137 peuvent apparaître aux terminaux de sortie si le terminal de
verrouillage de sécurité est fermé. Ouvrez le terminal de verrouillage de sécurité lorsque les connexions de sortie sont accessibles. Lorsque le terminal
de verrouillage de sécurité est ouvert, le niveau ou la limite de tension de sortie est limité à ± 40 V CC, et la protection se déclenchera si la tension
mesurée entre les terminaux HI et LO de l'appareil dépasse ± (42 Vpic ± 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.
Attention N'appliquez pas de tension aux entrées du connecteur de verrouillage de sécurité. Le connecteur de verrouillage est conçu pour accepter
uniquement des connexions à fermeture de contact passives, normalement ouvertes.
To ensure a system containing the PXIe-4137 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-4137, discharge all components connected to the measurement path.
Verify with a DMM before interaction with connections.
Safety Interlock System Integration
The PXIe-4137 includes a safety interlock circuit that places the outputs of the SMU in a safe state, regardless of the programmed state of the module.
• Do not short the safety interlock pins directly at the connector under any circumstances.
• Confirm on a regular basis that the safety interlock is functioning by performing a safety interlock test.
• Install mechanical detection switches that open the safety interlock circuit when the operator attempts to access the test fixture, disabling the hazardous
voltage ranges of the instrument.
• Ensure the mechanical detection switches close the safety interlock circuit only when the operator has properly closed all entry points to the test fixture
enclosure, enabling hazardous voltage ranges on the instrument.

Safety Interlock
The safety interlock feature is designed to prevent users from coming in contact with hazardous voltage generated by the SMU in systems that implement
protective barriers with controlled user access points.
Caution Hazardous voltages of up to the maximum voltage of the PXIe-4137 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 V peak ±0.4 V).
