II. Usage Instructions (Installation / Wiring / Maintenance)

1) Installation Configuration

32 Point DO Module (3624/3625/3664): 1 Module paired with 2 9661-610 (1–16, 17–32 each 1 Module)

Installation Location: Cabinet DIN Rail, Close to 115VAC Load Side

Hot Swap: Supports Online Replacement, No Shutdown Required

2) Wiring Specifications (115VAC Load Circuit)

Live Wire L: Input from Terminal Board Common Terminal → Channel + → Load One End

Neutral Wire N: Load Other End → System Neutral

Wire Diameter: 1.5–2.5 mm² Multi-strand Copper Wire, Matched with Cold Press Terminal

Fuse: 3A Slow-Melting; FUSE Red Light On Immediately Causes Power Off and Replacement Required

3) Fault Handling

FUSE On: Corresponding Channel Short Circuit / Overload → Replace 3A Fuse

CH Off: Check Module Output, 115VAC Power Supply, Load and Wiring

PWR Off: Check Terminal Board Power Supply, Flat Cable Connection
