Transformer connections per transformer nameplate connection diagram. MOVs are used on power stack assemblies for system voltages of 200 through 460 vac (as shown). Resistor/capacitor networks (DVDTs) are used on power stack assemblies in place of MOVs for a system voltage of 575 vac (not shown). K3 relay shown in deenergized state. K3 contact will close when power is supplied. K3 contact will open on stop command or system fault. CT1-CT3 are sized per Chart 2. Optional.
