NOTICEComments to remember about the 17” monitor. The monitor is the diagnostic monitor and is only connected to 115 VAC. The monitor powers down with the front end card rack. Power output from AC Control Box: When the monitor is not connected to the AC Control Box there is a leakage current which when measured with a DVM can indicate high voltage. When a load is applied, the voltage collapses to low voltage if the monitor is not switched on.
