Installation 3-3Part 1089210A04 2010 Nordson CorporationPower Supply Electrical ConnectionsPower ConnectionsNOTE: Power must be supplied from a dedicated power line.The customer power source must be wired in accordance with either theNational Electric Code, Part I or the Canadian Electrical Code, Part I, orlocal codes. At a minimum, 10 AWG 600 volt wire is required unlesssuperceded by local codes. Four #10−32 studs provide for line connection.Refer to the power supply ID plate for the input voltage and verify thetransformer tap wiring using 3-1 and 3-2. Measure the incoming powersource voltage from the main power supply. Incoming voltage transientsshall not exceed 150 volt amplitude and have a frequency content of lessthan 500 Hz. The power line input is three phase (three wire with ground). There are two large high-voltage transformers in the power supply.Each has a terminal block with H1, H2, and H3 terminals. Refer toTable 3-1. The power for the control electronics is provided from transformer T3. Ifan internal blower is used, a larger T3 is required. Both transformershave the same voltage range tap selections, as shown in Table 3-2. The transformer taps must be set in the same range. Only the taps onthe two identical power transformers need to be changed.Table 3-1 High Voltage Transformer Taps (T1 and T2)Voltage Range Transformer Tap440−480 H1−H3380−440 H1−H2Table 3-2 Control Transformer Taps (T3)Voltage Transformer Tap480 H1 and H4400 H1 and H3380 H1 and H2Front of Power Supply High VoltageHigh VoltageT2 T1T3Control TransformerExternal BlowerTransformer T3Internal BlowerTransformer T3Figure 3-2 Transformers Identified in Power Supply |
