General Wiring Considerations
1. Control wires and Power wires cannot be located in the same conduit (NEC Article 725).
2. When routing the interface wiring, do not route it up against anything that could cut or
chafe the wiring. do not route the wire up against any hot or potentially hot object.
3. Make sure that all the electrical components (generator set, transfer switch, battery
charger, etc.) share a common hardwired ground.
4. Check with your local building inspector to determine what you must do to comply with
the local regulations for grounding of this type of permanent installation.
AE8 Electrical Connections Applies only to AE8 Enclosed and Open Series Generators
Single Phase Power Connections
The generator has a 240V single phase AC output. These connections are made at the power
terminal box shown in Figure 3-3.

Remote Start and Battery Charger Connections
Figure 3-4 shows the connections for the battery charger and the remote start contacts of the
transfer switch. When the Remote Start Switch is closed, the generator will start. The unit will
remain running until this connection is opened. When the Remote Start Switch is opened, the
control circuits allow the engine to run for approximately 60−90 seconds before it shuts off. This
time delay allows the engine to run unloaded to cool down before stopping.
