Remote Start and Battery Charger Connections
Figure 3-10 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.
