How should I mount the accessory to avoid loosening during operation?
Fit the two supplied mounting screws with the provided spring washers and tighten to the specified torque of 0.5–0.7 N·m
using adhesive on the threads is recommended to resist vibrational loosening.
Can the key be used while the machine is running to bypass safety functions?
The accessory must not be used to override safety
circuits should be arranged so machinery cannot operate when the holding key is inserted in the door switch.
What precautions apply to handling and installation?
Avoid applying excessive force to the tip, do not drop the key, and stop use if deformity or breakage occurs
only use the specified D4NS door switch mounting orientation.
What cable requirements and sealing details must I observe when fitting nearby cabling?
Use multi-core cable AWG20–18 (0.5–0.75 mm2) and a cable diameter of 8.0–13 mm with the correct conduit connector assembly to maintain seal performance.
