Decommissioning – Removing the Plug from the Relay
Dismounting the relay will lead to a loss of the protection functionality.
Ensure that there is a back-up protection. If you are not aware of the
consequences of decommissioning the device – STOP! DO NOT start.
Inform SCADA before you start.
Switch-off the power supply.
Ensure that the cabinet is de-energized and that there are no voltages that
could lead to injury of personnel.
Disconnect the terminals at the rear-side of the device. DO NOT pull any
cable – pull on the plug! If it is stuck, use a screw driver.
Fasten the cables and terminals in the cabinet by means of cable clips to
ensure that no accidental electrical connections are caused.
Hold the device at the front-side while removing the mounting nuts.
Remove the device carefully from the cabinet.
In case no other device is to be mounted or replaced, cover/close the cut-
out in the front-door.
Close the cabinet.
