INPuT VOLTAGE RECONNECT PROCEDuRE

When received directly from the factory, units are con- nected for, 460 VAC. If 460 VAC is the desired input, then the machine may be connected to the power sys- tem without any setup required inside the reconnect door. For other voltages refer to the instructions locat- ed on the Reconnect Panel Access Door or follow the instructions below.
