Verification and power up
WARNING!:
It is recommended that the cover of the OVRHSP(SR) series unit along with its associated cabling be installed prior to
applying power. The monitoring harness, which exits the epoxy and connects to the input connector on the monitor board,
contains line voltage when power is applied to the unit.
Apply power to the OVRHSP(SR) series unit by closing the overcurrent protection
device or switch feeding the suppressor.
For compact OVRHSP units (60–100kA)
Verify that all indicating lights are illuminated. The indicating lights extinguish only upon
failure of one or more phases (indicating an alarm condition).
For standard OVRHSP units (120–400kA) or advanced
monitoring option (60–100kA) and OVRHSR units
Verify that all indicating lights are illuminated. The lights extinguish 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
audible alarm.
CAUTION:
Pressing the "Alarm silence" button when the alarm has not triggered will
prevent the audible alarm from sounding during a failure.
For OVRHSP units with surge counter option
(Not available on 60–100kA or OVRHSR units)
The number of surges detected by the SPD is displayed on an eight digit LCD display
on the front of the OVRHSP door. The LCD counter is battery backed to maintain the
number of surges even during a power loss. Press the reset button on the counter to
reset the surge count.
