The way I read it No Electrical Panels or Electrical Equipment other then required to power or Control the elevator is allowed in this room. Example (Main Electrical SERVICE Panel). (Not Allowed ) Panels or Disconnect Switches for feeding Elevator Equipment or Mtrs (Allowed).
John hit it on the head. Only elevator related equipment is allowed. ANS1 17.1 is a common Elevator Code to go by. What it really gets fun is fire detection, and sprinklers in the shaft.
