SECTION 8 | Installation
Block (10, Fig 6.1a) are shorted. The inverter will switch OFF when the relay contact /
switch is opened and short is removed across terminals 1 and 2 of the Terminal Block
(10, Fig 6.1a)
• 2-Wire ON/OFF Control Using Switched DC Voltage (10-33VDC), Fig 8.2(b):
!
CAUTION!
1. Please ensure correct polarity of wiring connection. Positive (+) of the external DC
source should be connected to Terminal 3 of the Terminal Block (10, Fig 6.1a) and
Negative (-) to Terminal 4. In case the polarity is reversed, the ON/OFF control will
NOT operate. The input to these terminals is protected against reverse polarity
2. Use 1A fuse as shown as close to the DC source as possible

INFO
The 10-30VDC external control signal on terminals 3 and 4 of the Terminal Block
(10, Fig 6.1a) feeds to an internal Opto-Isolator. Hence, the Negative Ground of the
external 10-30VDC source can be isolated from the Negative Ground of the Battery
input to the inverter.
The inverter will switch ON when the external relay contact / switch is closed [External DC
voltage (10-33VDC) is fed to terminals 3 and 4 of the Terminal Block (10, Fig 6.1a)]. The
inverter will switch OFF when the external relay contact / switch is opened [External DC volt-
age (10-33VDC) is removed from terminals 3 and 4 of the Terminal Block (10, Fig 6.1a)].
• 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.
