voltage type system, 12VDC or 24VDC. Connect the Positive (+) terminal of the external
system to the Positive (+) terminal on the weak system. Connect the Negative (-) terminal of
the external system to the Negative (-) terminal of the weak system. Always disconnect the
two systems in reverse order.
