Section 4 says:

UPS-MIB DEFINITIONS ::= BEGIN

   IMPORTS
       MODULE-IDENTITY, OBJECT-TYPE, NOTIFICATION-TYPE,
       OBJECT-IDENTITY, Counter32, Gauge32, Integer32
           FROM SNMPv2-SMI

         AutonomousType
           FROM SNMPv2-TC
       MODULE-COMPLIANCE, OBJECT-GROUP
           FROM SNMPv2-CONF;


It should say:

UPS-MIB DEFINITIONS ::= BEGIN

   IMPORTS
       MODULE-IDENTITY, OBJECT-TYPE, NOTIFICATION-TYPE,
       OBJECT-IDENTITY, Counter32, Gauge32, Integer32
           FROM SNMPv2-SMI
       DisplayString, TimeStamp, TimeInterval, TestAndIncr,
         AutonomousType, TEXTUAL-CONVENTION
           FROM SNMPv2-TC
       MODULE-COMPLIANCE, OBJECT-GROUP
           FROM SNMPv2-CONF;


Notes:

Textual conventions are used within this MIB, but the macro "TEXTUAL-CONVENTION" itself is not imported, as it should (RFC 2578 §3.2).

Section 4.8 says:

upsShutdownAfterDelay OBJECT-TYPE
       SYNTAX     INTEGER (-1..2147483648)
       UNITS      "seconds"
       MAX-ACCESS read-write
       STATUS     current
       DESCRIPTION
               "Setting this object will shutdown (i.e., turn off)
               either the UPS output or the UPS system (as determined
               by the value of upsShutdownType at the time of
               shutdown) after the indicated number of seconds, or
               less if the UPS batteries become depleted. Setting
               this object to 0 will cause the shutdown to occur
               immediately.  Setting this object to -1 will abort the
               countdown.  If the system is already in the desired
               state at the time the countdown reaches 0, then
               nothing will happen.  That is, there is no additional
               action at that time if upsShutdownType = system and
               the system is already off.  Similarly, there is no
               additional action at that time if upsShutdownType =
               output and the output is already off.  When read,
               upsShutdownAfterDelay will return the number of
               seconds remaining until shutdown, or -1 if no shutdown
               countdown is in effect.  On some systems, if the agent
               is restarted while a shutdown countdown is in effect,
               the countdown may be aborted.  Sets to this object
               override any upsShutdownAfterDelay already in effect."
       ::= { upsControl 2 }

   upsStartupAfterDelay OBJECT-TYPE
       SYNTAX     INTEGER (-1..2147483648)

       DESCRIPTION
               "Setting this object will shutdown (i.e., turn off)

   upsStartupAfterDelay OBJECT-TYPE
       SYNTAX     INTEGER (-1..2147483647)
       UNITS      "seconds"
       MAX-ACCESS read-write
       STATUS     current
       DESCRIPTION

Notes:

The upper limit of the ranges of upsShutdownAfterDelay and upsStartupAfterDelay points to the intention to use a 32-bit signed integer.
The biggest positive value of a 32-bit singed integer, however, is 2147483647. On a 32-Bit system the upper range given within RFC1628 (2147483648) is so large that is is unsigned, which conflicts with the limitation to 32 bits.
As 2147483648 seconds is more than 68 years, it seems preferable to change this to 2147483647, loosing 1 second but gaining the ability to be implemented with 32 bits.

Section 4 says:

       OBJECT     upsOutputSource
       SYNTAX     INTEGER {
           normal(2),
           battery(4)
       }
       DESCRIPTION
               "Support of the values other(1), none(2), bypass(4),
               booster(6) and reducer(7) is not required."

It should say:

       OBJECT     upsOutputSource
       SYNTAX     INTEGER {
           normal(3),
           battery(5)
       }
       DESCRIPTION
               "Support of the values other(1), none(2), bypass(4),
               booster(6) and reducer(7) is not required."

Notes:

This error appears 3 separate times, in the MODULE-COMPLIANCE definitions upsSubsetCompliance, upsBasicCompliance, and upsFullCompliance.

The wrong numbers are specified with the named values, which must match the OBJECT-TYPE definition of upsOutputSource.
