Safety Instructions

DANGER: HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Before servicing this device:

• Disconnect all power before servicing equipment.
• Place a “DO NOT TURN ON” label on all power disconnects.
• Lock all power disconnects in the open position.
• Install and close all covers before applying power or using this device.

Failure to follow these instructions will result in death or serious injury.

WARNING: IMPROPER INSTALLATION

• Do not use the safety limit switch as a stopper or as a centering device for a moving guard.
• Use a physical stop designed for that purpose.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

WARNING: IMPROPER COVER CLOSING

• Close and screw the cover following the specified tightening torque values.
• Lock with the manual locking key.
• Remove the manual locking key and store it in a safe place.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Installation and Wiring Diagrams

The document includes detailed wiring diagrams for various configurations, including M23 19-pin connectors and standard contact arrangements (NC+NO, NC+NC+NO, etc.). It also illustrates the head orientation and adjustment of actuating keys.

Wiring Notes:

• Safety pre-wiring is mandatory (22-41).
• PE (Protective Earth) wiring is required for XCSLF/XCSLE 19-pin models.
• The document provides examples of connecting the switches with XPSUAF monitoring units for Category 3 PL=d and Category 4 PL=e safety levels.

Maintenance

Regular checks are imperative:

• Verify the mechanical adjustment of the product with the actuating key.
• Check for wear; do not use devices beyond catalog specifications.
• Ensure proper electrical switching function.
• Modifying the devices is forbidden.

Schneider Electric disclaims all liability in case of non-compliance with the requirements of this notice.

Contact Status and Functionality

The document details the contact states (open/closed) and solenoid states (energized/unpowered) under various conditions, including power disconnection and machine operation sequences. It also explains the function of the LEDs (green for machine safety circuit, orange for solenoid status).
