Danfoss VLT FC 103 Programming Manual page 36

Parameter Description
NOTE
The frequency converter has no back up of the clock
function and the set date/time will reset to default
(2000-01-01 00:00) after a power down unless a Real Time
Clock module with back up is installed. If no module with
back up is installed, it is recommended the clock function
is only used if the frequency converter is integrated into
the BMS using serial communications, with the BMS
maintaining synchronization of control equipment clock
times. In 0-79 Clock Fault it is possible to program for a
Warning in case clock has not been set properly, e.g. after
a power down.
NOTE
If mounting an Analog I/O MCB 109 option card, a battery
back-up of the date and time is included.
