Using Molex® Connectors

Each D8128D Module is supplied with a 30 cm (12 in.) female-to-female Molex cable assembly.

P1 and P2 are Molex connectors that parallel the COM, IN, OUT, and +12.0 VDC terminals on the terminal strip. In installations with multiple D8128Ds, use these connectors (as opposed to terminals) with the supplied cable; however, when connecting D8128D Modules directly to the control panel, the terminal strip is easier to use.

The Molex connectors provided are "keyed" (Molex plug can fit in only one direction). Ensure that the connector is attached correctly: the red wire is on the bottom of P1 (or P2) and the black wire is on the top.

When connecting multiple D8128Ds to a control panel, you can connect the control panel terminals to P1 or the COM, IN, OUT, and +12V terminals on the first D8128D. Then connect P2 of the first D8128D to P1 of the second D8128D and so on (Figure 22).
