I think it should be LSC2A (not LCS2A). LSC is for the Loss of Service Continuity. IEC 62271-200 describes it in section 8.2.3 with the example as

"LSC2A: When accessing components of one functional unit, the other functional units of the switchgear and controlgear may be kept in service.

Example LSC2A for withdrawable designs : In practical terms, this means that the incoming HV-cables of that functional unit shall be made dead and earthed and the circuit shall be disconnected and separated (physically and electrically) from the busbars. Busbars may be kept live."

It's a typing mistake, more than anything.
