Safety Guidelines for Hazardous Voltages
Caution Ensure that hazardous voltage wiring is performed only by qualified personnel adhering to local electrical standards.
Attention S'assurer que le câblage à tension dangereuse est effectué par du personnel qualifié respectant les normes électriques locales.
Caution Do not mix hazardous voltage circuits and human-accessible circuits on the same product.
Attention Ne pas combiner des circuits avec des tensions dangereuses et des circuits accessibles aux personnes sur le même produit.
Caution When product terminals are hazardous voltage LIVE, you must ensure that devices and circuits connected to the product are properly
insulated from human contact.
Attention Lorsqu'une haute tension dangereuse est appliquée aux bornes du produit, vous devez vous assurer que les appareils et les circuits auxquels
il est connecté sont correctement isolés de tout contact humain.
Safety Interlock System Integration
The PXIe-4135 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-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 V peak ±0.4 V).
Attention Des tensions dangereuses allant jusqu'à la tension maximale du PXIe-4135 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.

Attention Ne pas connecter le produit à des signaux dans les catégories de mesure II, III ou IV et ne pas l'utiliser pour effectuer des mesures dans ces
catégories.
Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage.
MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary
circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage
sources, and electronics.
Note Measurement Categories CAT I and CAT O are equivalent. These test and measurement circuits are for other circuits not intended for direct
connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.
Note Isolation voltage ratings apply to the voltage measured between any channel pin and the chassis ground connector of the front panel. When
operating channels in series or floating on top of external voltage references, ensure that no terminal exceeds this rating.
Safety Compliance Standards
This product is designed to meet the requirements of the following electrical equipment safety standards for measurement, control, and laboratory use:
• IEC 61010-1, EN 61010-1
• UL 61010-1, CSA C22.2 No. 61010-1
