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.
