WARNING: Shock Hazard
During an error shutdown, the inverter's output terminals are not live. However,
if the inverter recovers from a shutdown, the terminals will become live without
notice. Several error shutdowns can be recovered automatically, including Low
Battery V, High Battery V, and Over Temperature. See page 62.
Table 7
Possible Remedy
Use a DC voltmeter to check the voltage directly on the DC
terminals. If not present, the problem is external. If present, the
inverter could be damaged. Contact OutBack Technical Support.
See the Installation Manual for the location of the jumper. Confirm
the jumper is present. If missing, replace the jumper. Or follow the
Installation Manual instructions to install an external switch.
The FXR inverter is given an initial Off command in the factory.
With DC present, use narrow pliers to remove the jumper from its
pins. Once removed, install it again. This is the equivalent of
"jiggling the switch."
MATE3 system display only: Set to On with the INVERTER hot key.
NOTE: The ON/OFF jumper must be installed.
MATE3 system display only: If constant power is required, set to On
with the INVERTER hot key. (If this setting was intentional, then
no action is required.)
Troubleshooting
In troubleshooting, AC
voltages can be measured
at the attachment screw
for each AC conductor.
