How should the safety switch be positioned during troubleshooting?

During troubleshooting, it is essential to ensure that the equipment is not operational to avoid any hazards. Positioning the safety switch in the off position achieves this by cutting power to the motor and associated systems. This precaution protects both the technician and the equipment during the troubleshooting process, as it eliminates the risk of accidental starts or electrical shocks while testing or making adjustments.

The other options do not provide the same level of safety. Automatic mode would allow the system to function normally, posing a risk during troubleshooting. Reset mode may re-enable the system functionality, which again could lead to unintentional operation. Maintenance mode, while sometimes intended for safe servicing, does not guarantee complete power disconnection, which is essential during troubleshooting. Therefore, ensuring the safety switch is in the off position is the safest practice for troubleshooting.
