REMOVE POWER FROM THE RF/PDU CABINET BEFORE ATTEMPTING TO REMOVE ANY COMPONENTS FROM THE SYSTEM

The PDU has a clear plastic cover over the breaker panel. This clear plastic cover allows for local power isolation using individual breakers for sub components in the Signa System. This procedure describes how to shutdown GOC and perform LOTO. Prior to performing work on the GOC, the steps in this Lock Out Tag Out Procedure must be performed by a LOTO Authorized GE Field Engineer. Completing all steps in this procedure will ensure a safe environment when working on these parts.
