*The
PCNS SHUTDOWN REQUIRED TIME = the shutdown delay + the shutdown command duration.
When the default of 70 seconds is added, the time is always rounded up to nearest minute. E.g., a
total here of 3 min 50 sec is rounded up to 4 min; a total of 2 min is still rounded up to 3 min.
Notes:
The 70 sec. mentioned is the default OS shutdown time for PCNS.
PCNS never changes the NMC Low Battery Duration field value.
With PCNS v3.x, the Maximum Required Delay value is never used by the NMC for a UPS with
outlet groups.
