Operating Instructions
Once the emergency stop button is properly set up, follow these steps for operation:
- Power On Equipment: Since the emergency stop switch operates in a normally open state, you must first turn on the power switch of your connected electrical equipment. Power will then flow through the emergency stop button to your device.
- Normal Operation: Your equipment will now operate as usual.
- Emergency Stop: In case of an emergency or when immediate power cut-off is required, firmly press the large red emergency stop button. This will instantly cut power to the connected equipment.
- Resetting the Button: To restore power after an emergency stop, twist the red button clockwise until it pops out to its original position. Then, you may need to cycle the power switch on your equipment to resume operation.

Maintenance
The MARSTEK Emergency Stop Button Kit requires minimal maintenance due to its durable and sealed design.
- Cleaning: Periodically wipe the exterior of the switch with a damp cloth to remove dust and debris. Do not use harsh chemicals or abrasive cleaners.
- Inspection: Regularly inspect the cable, plug, and switch housing for any signs of damage, wear, or loose connections. If any damage is found, discontinue use immediately and replace the unit.
- Water Resistance: The unit is IP67 rated, providing protection against dust ingress and temporary immersion in water. Ensure the cable glands are tight and the housing is not compromised to maintain this rating.
Troubleshooting
If you encounter issues with your emergency stop button, consider the following:
- No Power to Equipment:
- Ensure the emergency stop button is in the reset (untwisted) position.
- Verify that your electrical equipment's own power switch is turned ON.
- Check if the emergency stop button's plug is securely inserted into the wall outlet.
- Confirm that the equipment's plug is securely inserted into the back socket of the emergency stop button.
- Test the wall outlet with another device to ensure it is supplying power.
- Emergency Stop Button Not Resetting:
- Ensure you are twisting the button clockwise firmly until it clicks and pops out.
- Check for any obstructions around the button mechanism.
If problems persist, contact customer support.
