Installation Guide
5.4.5 Generator Start Using GenMan
The Sunny Island 3324/4248 can also automatically start generators having more
than a 2-wire start contact by using the optionally available generator manager
(GenMan). As soon as the generator has started, the GenMan confirms proper
operation by sending a signal to the G_Run connections of the Sunny Island 3324/
4248.
.
Pay attention to the correct connection polarity when installing.
• Connect the GenMan minus output Gen Ready– to the G-RUN– terminal of the
Sunny Island 3324/4248.
• Wire the GenMan positive output Gen Ready+ to the G-RUN+ terminal of the
Sunny Island 3324/4248.
