CONTROL COMPONENT INDICATORS
Various indicators are provided to display the operational status of components in the control
cabinet. Figures 5-14 through 5-17 locate and define the indications shown on these components.
Where applicable, corrective actions are included to assist the operator in fault analysis.
Dangerously high voltage is present in the control cabinet. Since opening the control cabinet door
and bypassing the cabinet purge system is required to check the indicators, only trained, qualified
personnel should be permitted to perform these procedures. Use extreme caution to ensure that
the surrounding atmosphere is free of hazardous fumes before opening the cabinet door and
bypassing the purge system.
! ONLY TRAINED, QUALIFIED PERSONNEL SHOULD BE
PERMITTED TO OPEN CONTROL CABINET DOOR WHILE POWER IS
APPLIED.
HAZARD! BE CERTAIN THAT SURROUNDING ATMOSPHERE IS
CLEAR OF ALL POTENTIALLY EXPLOS
IVE GASES BEFORE OPENING
