WARNINGS

Jobs can be submitted up to 2037. If jobs were submitted any later than 2037, an error message will

display "BAD DATE".

Some UPS units limit the time that can elapse between the time the power is turned off and the time it is

turned back on. Please see your UPS documentation for information about limitations.

If the date argument begins with a number and the time argument is also numeric (and without sufﬁx),

the time argument should be a four-digit number that can be correctly interpreted as hours and minutes.

Do not use both

next and + increment within a single power_onoff command; only the ﬁrst operator

is accepted and the trailing operator is ignored. No warning or error is produced.

The power cord must be disconnected before servicing the unit.
