I removed it because requesting a specific 3-phase variable does not
work (at least on the units I have to hand).

Compare the following:

hostadm:/etc/nut# snmpget -v 1 -c public \
ups-pf34-2 .1.3.6.1.4.1.232.165.3.3.4.1.2.1
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: CPQPOWER-MIB::upsInputVoltage.1

hostadm:/etc/nut# snmpget -v 1 -c public \
ups-pf34-2 .1.3.6.1.4.1.232.165.3.3.4.1.2  
CPQPOWER-MIB::upsInputVoltage.1 = INTEGER: 245

This suggests to me that requesting the 3-phase values will cause an
error. Unless I have misunderstood how the driver grabs the values. Does
the SU_INPUT_3 flag tell the driver to ask for (for
example) .1.3.6.1.4.1.232.165.3.3.4.1.2, and then only grab the one that
it asked for?

I'll stick the 3-phase stuff back in if this is the case.
