NU 3600
For connection, see chapter "Connect battery monitor" on page 14.
7.3 Switching signal 12 V
A 12 V potential-free signal at Signal OUT (3) can be activated when there is mains from grid (AC1-IN,
1). This signal can be used to indicate the mains input for example by lighting an external lamp. For
connection, see chapter "Connect switching signal 12 V" on page 14.
The signal can be delayed by 2 s, 2 min, 10 min or not at all, by setting the jumper position. The
default setting is 2 min delay.
7.4 Combining both 12 V signals
The two 12 V signals (3, 4) can also be connected in series. That means that the switch output
(AC-OUT2, 5) will have power either only when there is mains from grid (AC1-IN, 1) or from inverter
(AC2-IN, 7). With a delay time, it can for example mean that an air conditioner starts 10 minutes after
mains voltage has been connected (fig. 5, page 7).
