Device
he boards have been manufactured as a welded construction with a protective anticorrosive
coating of polyester dust. There has been provided one-sided service at the front part of the
boards, made possible through one or two doors with fitted locks. The apparatuses in the main
circuits of the boards have been fitted on an installation panel with standard instruments.
The symbols of the apparatuses and the connecting cables have been put on them or near
them meeting the requirements of the diagrams using a secret method. The electric diagram of
each board has been fitted on the inside of the door.
Working Conditions
The boards are designed for work in the open or under cover in temperate climate
