Current Sharing
Notice in the wiring schematic (Figure 5-23) that pins A, C and
E in each row of J1/J2 are connected together on the PC board.
When connecting high-current (>3 amp) loads, wire across all
three pins in each row of P1/P2 (see Figure 5-24). This ensures
current sharing across all pins and prevents premature pin
failure from excessive current flow.
CAUTION
Connecting high-current (>4 amp) loads without wiring across all
three pins in the row can cause premature pin failure.
