Current Sharing
Notice in the wiring schematic (Figure 5-14) that pins A, C and
E in each row of J1 are connected together on the PC board.
When connecting high-current (>3 amp) loads, wire across all
three pins in each row of P1 (see Figure 5-15). This ensures
current sharing across all pins and prevents premature pin
failure from excessive current flow.
