Self-service terminal

A self-service terminal comprising a plurality of devices is described. The devices comprise: a racking handle for moving that device from an operational position to a maintenance position; a primary visual identifier (such as a bright color) associated with the racking handle, where the primary visual identifier is common for all of the racking handles and is not used for any part of the device except a racking handle; and a secondary visual identifier associated with any other parts of the device that may be safely touched, where the secondary visual identifier is visually distinct (for example, by using a different color) from the primary visual identifier.
