4. Verification and Power Up
WARNING: It is recommended that the cover of the LowProfile unit along with its associated cabling be
!
installed prior to applying power. The monitoring harness, which exits the epoxy and connects to J2 on the
monitor board, contains line voltage when power is applied to the unit.
Apply power to LowProfile by closing the switch feeding the SPD.
Verify that all "Phase Protection Status" indicating lights are illuminated. The "Check System" indicating light illuminates
only upon failure of one or more phases (indicating an alarm condition). Audible alarm should not operate under normal
conditions. The audible alarm can be "muted" by pressing the "ALARM SILENCE" button, which subsequently will illuminate
the "ALARM SILENCED" light. Pressing the "ALARM SILENCE" button again will enable the alarm.
