What is the correct sequence of operations before servicing an elevator door motor?

The correct sequence of operations before servicing an elevator door motor begins with Lockout and Tagout, which is critical for ensuring the safety of personnel by preventing the accidental energization of the elevator while maintenance is performed. This step is essential to protect workers from potential hazards associated with unexpected movement or electrical shock.

Following the Lockout and Tagout procedure, the next logical step is inspection. This involves assessing the condition of the equipment, identifying any wear or damage that could impact the safe performance of the door motor. An inspection helps in understanding if any repair or replacement is necessary before proceeding further.

The final step, checking cables, is necessary to ensure that all connections to the motor are secure and functional. Inspecting cables ensures that they are not frayed or damaged, which could lead to malfunctioning of the motor or unsafe operation of the elevator door.

This sequence provides a comprehensive approach to servicing the elevator door motor by prioritizing safety first, followed by assessing the condition of the equipment, and finally ensuring functionality through a check of specific components.
