CONTROL COMPONENT INDICATORS
Various indicators are provided to display the operational status of components in the control
cabinet. Figures 5105-3 through 5105-6 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.
WARNING! DANGEROUSLY HIGH VOLTAGE IS PRESENT. ONLY TRAINED,
QUALIFIED PERSONNEL SHOULD BE PERMITTED TO OPEN CONTROL
CABINET DOOR WHILE POWER IS APPLIED.
WARNING! HAZARDOUS GASES CAN CAUSE EXPLOSION. BE CERTAIN
THAT SURROUNDING ATMOSPHERE IS CLEAR OF ALL POTENTIALLY
EXPLOSIVE GASES BEFORE OPENING CONTROL CABINET DOOR.
