DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
� Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices.
See NFPA 70E.
� This equipment must only be installed and serviced by qualified electrical personnel.
� Turn off all power supplying this equipment before working on or inside equipment.
� Always use a properly rated voltage sensing device to confirm power is off.
� Replace all devices, doors and covers before turning on power to this equipment.
Failure to follow these instructions will result in death or serious injury.

CAUTION
LOSS OF BRANCH CIRCUIT POWER AND SURGE PROTECTION
In the event that the surge protective elements of the TITAN Hardwired SPD have been damaged (i.e.
excessive surge energy, power system anomaly, etc.), the surge protective elements can lose their
ability to block power system voltage and attempt to draw excessive current from the line. This SPD
is equipped with overcurrent and overtemperature protection that will automatically disconnect the
surge protective elements from the mains should the surge protective elements be damaged.
The effects of damaged surge protective elements and the subsequent operation of the automatic
overcurrent and overtemperature protection must be considered when applying an SPD, particularly
when critical loads requiring continuity of power or continuity of surge protection are present on the
power system. The following items should be considered when applying an SPD:
� Tripping of the branch circuit breaker feeding the SPD can occur when the surge protective
elements are damaged. Do not connect the SPD to a branch circuit feeding a load requiring
continuity of power (i.e. central computer or control systems, safety-critical equipment, critical
processes or systems, etc.) unless the branch circuit breaker trip characteristic has been
coordinated with the overcurrent protection inside the SPD.
� Periodic inspection of the state of the status indicator lights on the SPD should be made as part of
the preventive maintenance schedule. The SPD should be promptly serviced when an alarm
state exists.
� For unmanned, inaccessible, or critical installations, the dry contacts should be used to signal an
alarm state to the central supervisory system.
� In addition to the preceding items, the use of multiple SPDs to achieve redundancy should be
considered for critical applications.
Failure to follow these instructions can result in loss of power or loss of surge protection
that can cause injury or equipment damage.

TITAN HARDWIRED PRODUCTS Surge Protective Device (SPD)

CAUTION
LOSS OF SURGE PROTECTION
� During installation into an electrical system, SPDs must not be energized until the electrical system
is completely installed, inspected, and tested. All conductors must be connected and functional,
including the neutral, if applicable. The voltage rating of the device and system must always be
verified before energizing the surge protective device.
� Any factory or on-site testing of power distribution equipment that exceeds the normal operating
voltage, such as high-potential insulation testing, or any other tests where the suppression
components will be subjected to voltages higher than their rated turn-on voltage must be performed
with the suppressor disconnected from the power source. The neutral connection at the SPD must
also be disconnected prior to performing high-potential testing and then reconnected upon
completion of the test.
Failure to follow these instructions can result in equipment damage.

Proper installation is imperative to maximize the Hardwired SPDs
effectiveness and performance. The installer should follow the steps
outlined in this instruction bulletin to ensure proper installation. Read
the entire instruction bulletin before beginning the installation. These
instructions are not intended to replace national or local electrical codes.
Check all applicable electrical codes to verify compliance. Installation
of surge suppressors should only be performed by qualified electrical
personnel.
NOTE: SPDs are designed for use on the load side of the service entrance
disconnect only.
Inspect the entire shipping container for damage or signs of mishandling
before unpacking the device. Remove the packing material and further
inspect the device for any obvious shipping damage. If any damage is
found and is a result of shipping or handling, immediately file a claim with
the shipping company.
The device should be stored in a clean, dry environment. Storage
temperature is -40 to +65 �C (-40 to +149 �F). All of the packaging
materials should be left intact until the device is ready for installation.
