SECTION 9 |
Shut Down Due To Fault Conditions & Reset
!
CAUTIon! Please note that "shut down" indicates that the output has been stopped.
The unit will not completely turn oFF under "shut down" condition.
The unit will shut down in certain critical fault conditions and will require manual reset. Switch OFF the unit using the ON/OFF key. Remove the cause of
defect and switch ON the unit again.
In some cases, the unit may get latched and will not switch OFF. In such cases, remove the AC & DC input connection, wait for 5 minutes, reconnect
and then switch ON.
Protections
Table 9.2 gives the details of protections provided for safe and reliable operation of the unit:
SYMPToM
