KILOWATT difference < 20 kW)(max. AMPS difference< 40 A)If actual differences exceed the allowable range, press AC CIRCUIT INTERRUPTER OFFpushbutton switch and recheck frequency and voltage settings (item 3) for theGenerator Sets150 kW.Power Distribution Unit (PDU)After switching ON the EPP AC circuit, the PDU will be supplied withcontrol voltage and 400 Hz voltage.Perform the lamp test.If RS is switched ON, output indicators J1, J2, and J3 are on.If ECS is switched ON, output indicator J4 is on.Converter OperationPreparation1.Connect EPP to ground.2.Connect all power supply cables and control cables between convertercontrol cabinet and PDU.3.See converter operating instructions for subsequent procedures.Figure 2-17 Generator Set 150 kW Short Instructions P/ate (sheet 2 of 2).2 - 52
