Troubleshooting
1. Press and hold the Power
ON/OFF pushbutton for 15
seconds.
2. Watch the Charging/
Inverting Status LED, after
approximately 15 seconds it
should come on and flash
rapidly to indicate the inverter

go off after the pushbutton is
released.

6.3 Powering Down the Inverter
Note: The router is normally connected to multiple inverters. The procedure below should be
performed on all the inverters in the system (all at once) to ensure a complete system power-down.
To power-down the inverter:
1. Remove all AC power (utility or generator power) to the inverter.
2. Remove any accessories connected to the inverter and or/router.
3. Remove all DC power to the inverter (open all the inverter DC disconnects or disconnect the
positive battery cable to the inverter).
4. Remove the router from the inverter—ensure the router display is blank.
5. After all accessory devices have been disconnected from the inverter(s) and the inverters
have been disconnected from all power for 30 seconds, reconnect power to all inverters,
reconnect all accessory devices and the router, and resume operation.
Info: If DC disconnects are not used, there may be a momentary spark when the positive
battery cable is connected to the inverter’s terminal. This is normal and indicates that
the inverter’s internal capacitors are being charged.
6.2 Performing an Inverter Reset
Press and hold the Power ON/OFF button (see Figure 6-1) for approximately fi fteen (15) seconds
until the Charging/Inverting Status LED comes on and fl ashes. Once the fl ashing has begun,
release the Power ON/OFF button. The Charging/Inverting Status LED goes off after the button
is released. After the inverter reset is completed, press the Power ON/OFF button to turn the
inverter ON.
Some older inverter models do not allow an inverter reset. If the inverter reset fails, you need to
power-down the inverter using the procedure in Section 6.3 below. In either case, if an internal
fault does not clear, the inverter requires repair at a Sensata Authorized Service Center.
Info: The Power ON/OFF button is a small momentary type switch which operates by
lightly pressing and releasing.
Info: All adjustable settings in the router (except SETUP: 01B Screen Setup , CTRL: 03
Gen Control and TECH: 08 Show all Menus —which revert back to default) are saved
in non-volatile memory and are preserved until changed—even if an inverter reset is
performed or if all power to the router or inverter is removed.
