2.3 Pin Assignment

Pin assignment for all connectors on the EB1200M62-355JC is listed in the following sections.

2.3.1 Power Interface

The J1 power supply connector is used to supply all ICs and supply gate driver voltage, and
assignment. There are four screw terminals (J6, J7, J8, J9). Terminals J6 and J7 are used for connecting the drain terminals
of the half bridge switches to the OC pin of the gate driver, and terminals J8 and J9 are used for connecting to the high-
voltage DC rails (DC+, DC-) for voltage measurement.
