AZARD 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.

AUTION

OSS OF BRANCH CIRCUIT POWER AND SURGE PROTECTION

In the event that the surge protective elements of the 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 a 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 a 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 SPD’s 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.
