Connecting the remote contacts to an alarm

(If option chosen on the OVRHS3U)

For "fail-safe" Form "C" monitoring, use the labeled Form "C" wire

outputs to the alarm detection wires. Both outputs NO or NC

are available and either can be used dependent upon Negative or

positive logic choice. Relay contacts are rated for 1A, at 150Vac or

60Vdc maximum.

Relay contacts shown in the relaxed position

(protector alarm or loss of power).

Note: Maximum torque on terminals is 10 in-lbs.

CAUTION:

Do not assume the circuit is de-energized! Remove power before

performing any maintenance to these devices.

CAUTION:

Do not splice SPD conductors within the unit's enclosure or

manufacturer's warranty will be void. SPD's performance will be

limited severely if the conductors are A) too long B) are of too small

a wire gauge C) have too many bends or D) have sharp bends.

CAUTION:

Prior to installation, confirm and ensure the system configuration

and voltage rating of the surge protector being installed.
