How to install the mute switch on the distribution box

To install a mute switch on a distribution box, mount the muting distribution block securely, connect the switch to the designated muting station, and configure DIP switches for the desired muting function.

Step 1: Prepare the Distribution Box

Ensure the distribution box is properly installed according to safety standards. It should be mounted in a dry, accessible location with good ventilation, and all wiring should follow local electrical codes. Use appropriate IP/NEMA-rated enclosures for protection against dust and moisture, and ensure proper grounding and cable management inside the box .

Step 2: Mount the Muting Distribution Block

The muting distribution block can be mounted to a stand or DIN rail using two M4 screws. It cannot be mounted directly on the light curtain. Ensure the block is positioned for easy access to the muting station and sensor connections .

Step 3: Connect the Mute Switch

Use a pre-assembled muting station (e.g., Bulletin 800F) that includes a keyswitch and muting lamp. Connect the keyswitch to the muting distribution block according to the manufacturer's wiring diagram. The orange muting indicator and green OSSD status indicator on the muting station will show the operational status. For setups with two muting sensors, connect the sensors to the distribution block and then to the light curtain plug-in (catalog number 450L-APR-MU-8), .

Step 4: Configure DIP Switches

Set the DIP switches on the Bulletin 450L GuardShield muting connection plug-in to select the desired muting type (2- or 4-sensor muting). Follow the confirmation procedure in the manufacturer's manual to ensure correct configuration .

Step 5: Verify and Test

After wiring, perform a visual inspection and use a multimeter to check connections. Test the mute switch by activating it and confirming that the muting function works as intended, including the status indicators. Ensure that the override or reset functions operate correctly if required by your risk assessment .

Additional Tips

• Use compatible sensors with matching pinning and output polarity. The RightSight polarized retroreflective sensors are recommended, but other compatible sensors can be used .
• Label all connections clearly for future maintenance.
• Follow all safety guidelines to prevent electrical hazards during installation.

By following these steps, the mute switch will be correctly integrated into the distribution box, ensuring safe and reliable muting functionality for your system.
