Figure 5-27, Tfmr Overtemp Fault

• Tfmr Overtemp - This fault message is displayed when the TCO
(Temperature Cut-Out) opens and causes the inverter to shut down to
protect the internal power transformer from damage. When the TCO has
cooled down, the inverter will automatically restart and resume operation.
Remedy: If the fault occurs while Inverting, reduce the load on the
inverter; if it occurs while charging, turn down the charge rate. If
this fault occurs often, ensure the inverter is in a cool location, has
adequate ventilation, and the internal cooling fans are operational.

• No Inverter Comm - This fault message indicates that the remote is no
longer receiving any communication data via the Magnum Network.
Remedy: Reset the remote by disconnecting the remote commu-
nications cable from the inverter for 5 seconds and then reconnect
(see Figure 2-3). If the fault continues, check/replace the remote
cable.
