ON and OFF Wiring
Figure 19 ON/OFF Jumper and Connections
The
I
NV
O
N
/O
FF
jumper bridges two pins.
This jumper (J3) parallels the two
S
WITCH
I
NV
terminals on the terminal block. If either
connection is closed, this sets the inverter to
On as long as the internal programming has not
been set to Off with the system display. (The
inverter is given an external
OFF
command in
the factory. Its initial state will be Off.)
An inverter in the Off state will not invert.
However, it may still transfer power to loads
and charge batteries from an AC source.
Jumper On
If the system display is not present:
To turn the inverter initially On, remove the jumper briefly and then replace it. This requires
long-nose pliers or a similar tool. (This will change the internal programmed state to On.) After
this, removing the jumper will immediately turn the inverter Off.
Once the plastic
I
NV
O
N
/O
FF
jumper has been removed, the
S
WITCH
I
NV
terminals on the
terminal block can be used to wire a manual on/off switch or an emergency shutoff.
