RE: Model 170 with UPS on V4.2.0

[Neil Palmer <npalmer@xxxxxxxxxxx>]

In setting QUPSDLYTIM you first need to determine how long the UPS will
run with a typical load.
Most modern UPS' can display their estimated run time via
diagnostics/panel display/etc.
As a rule of thumb I would take that number and divide by 2, and that's
the highest value I would use for QUPSDLYTIM.
