82.2.1 Changing Transformer Taps ProcedureBefore beginning any work inside the charger enclosure ensure that all incoming AC supply and DC load wiresare de-energized. Verify that no voltage is present inside the case by using a voltmeter at all input and outputterminals.For 120 VAC Input Voltage:1. For terminal strip TS-3, connect a jumperwire from terminal 1 to terminal 2.2. For terminal strip TS-4, connect wiremarked D to terminal 3.3. For terminal strip TS-4, connect wiremarked E to terminal 1.Note that AC input 1 connects to terminal L1Note that AC input 2 connects to terminal L3For 208 VAC Input Voltage:1. For terminal strip TS-3: connect a jumper wire fromterminal 2 to terminal 3.2. For terminal strip TS-4: connect wire marked D toterminal 2.3. For terminal strip TS-4: connect wire marked E toterminal 3.Note that AC in 1 connects to terminal L1Note that AC in 2 connects to terminal L2For 240 VAC Input Voltage:1. For terminal strip TS-3: connect a jumper wire fromterminal 2 to terminal 3.2. For terminal strip TS-4: connect wire marked D to terminal 1.3. For terminal strip TS-4: connect wire marked E to terminal 3.Note that AC in 1 connects to terminal L1Note that AC in 2 connects to terminal L2ACin1 ACin2TS-3JumperConnectionTS-4D EINPUTVAC120 L1 L3 1-2 3 1208L1 L2 2-32 3240 1 3Figure 8 - Input Terminals Connection(Schematic – 240VAC input shown)Table 5 - Input Terminal Connections
