Diversified Electronics UPA-100 Series Data Sheet

The UPA-100 Power Alert reduces the risk of electrical arc flash by
pre-verifying the electrical isolation from outside of a control panel. Hard
wired to the circuit breaker or main disconnect, the UPA flashes whenever
voltage is present. Engineered with redundant circuitry, the Power Alert
is powered by the same voltage that it indicates.

OPERATION

The eight detector UPA-100 visually alerts to the presence of dangerous
AC or DC (Stored Energy) potentials occurring between any combination
of the four monitored input lines (L1, L2, L3, GND). Two LED indicators
are assigned to each input line and are designated “+” and “-”. For
each input line carrying an AC potential (bi-polar), both the “+” and “-”
LEDs will be active. A DC or Stored Energy potential will illuminate the
“+” LED for the positive line and the “-” LED for the negative line.

OSHA 1910.147 THE CONTROL OF HAZARDOUS ENERGY
(LOCKOUT/TAGOUT)

Following the application of lockout or tagout devices to energy isolating devices,
all potentially hazardous stored or residual energy shall be relieved, disconnected,
restrained, and otherwise rendered safe. (d)(5)(ii)

If there is a possibility of reaccumulation of stored energy to a hazardous level,
verication of isolation shall be continued until the servicing or maintenance is
completed, or until the possibility of such accumulation no longer exists. (d)(6)

“Verication of Isolation.” Prior to starting work on machines or equipment that
have been locked out or tagged out, the authorized employee shall verify that isola­tion and de-energization of the machine or equipment have been accomplished.
