Before customer handover, which action regarding temporary jumpers is required?

• A. Do not remove temporary jumpers before handover.
• B. Remove temporary jumpers before customer handover.
• C. Replace jumpers with new ones.
• D. Inspect jumpers for wear before handover.

Answer: (B)

Temporary jumpers are used during testing to simulate signals or bypass parts of the circuit. Before handing the escalator or moving walk over to the customer, those jumpers must be removed so the installation reflects its final, design-approved wiring. This prevents any temporary bypass from remaining in service, which could interfere with safety interlocks or control logic and create a hazardous or confusing situation for the customer. Replacing them with new jumpers isn’t necessary unless there’s a specific fault, and simply inspecting for wear doesn’t address returning the system to its proper final state. The required action is to remove the temporary jumpers before handover.
