• 1-Wire ON/OFF Control Using Switched DC Voltage from the Battery Supplying the
Inverter, fig 8.2(c) :
CAUTION!
1. Please ensure correct polarity of wiring connection. Positive (+) of the
!
battery voltage should be connected to Terminal 3. In case the polarity is
reversed, the ON/OFF control will NOT operate. The input to this terminal
is protected against reverse polarity.
2. Use 1A fuse as shown as close to the Battery input point as possible.
The inverter will switch ON when the external relay contact / switch is closed [Voltage
from the 12V / 24V battery supplying the inverter is fed to terminal 3 of the Terminal
Block (10, fig 6.1a)]. The inverter will switch OFF when the external relay contact
/ switch is opened [Voltage from the 12V / 24V battery supplying the inverter DC
voltage is removed from terminal 3 of Terminal Block (10, fig 6.1a)]. In a vehicle / RV,
the control voltage may be fed directly from the Ignition Switch. This will switch ON
the inverter when the Ignition is ON and switch OFF the inverter when the Ignition
is switched OFF.
