Equipment Connection Details
Generac Gateway Side Terminations | Description | Harness Wire Color | Equipment Side Terminations |
|---|---|---|---|
2 | DC+ | A0009887772 Red | TB1-42A |
1 | DC- | A0009887772 Black | TB1-2 |
6 | Engine Running | A0009887772 Purple | Hour Meter+ (Wire 70) |
7 | Not in Auto | A0009887772 Green | TB1-80 |
Harness Relay #1 | COM | A0009887772 Blue | TB1-3 |
N/O | A0009887772 White / Blue | TB1-4 |
Note that when using A0009887772 harness, terminal 5 on Generac Gateway is connected to battery negative. Therefore the common terminal on equipment controller Engine Running and Not in Auto signals should be connected to battery positive and the signals should be connected to the terminals mentioned in above table. In other words, this means outputs on equipment controller must source voltage to Generac Gateway inputs.
If the equipment controller outputs are sinking voltage, a 12/ 24 vdc (depending on battery voltage) relay needs to be connected between the controller output (for example, engine running) and common. The relay N/O contact would connect to terminal 6 on Generac Gateway and relay COM connects to battery positive post
