ASCO 430 Surge Protective Device (SPD)
Precautions
Precautions
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe
electrical work practices. See NFPA 70E, NOM-029-STPS or CSA Z462.
•
This equipment must only be installed and serviced by qualified electri
-
cal 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.
•
This equipment must be effectively grounded per all applicable codes.
Use an equipment-grounding conductor to connect this equipment to the
power system ground.
Failure to follow these instructions will result in death or serious injury.
WARNING:
This product can expose you to chemicals including
DINP, which is known to the State of California to cause cancer, and
DIDP which is known to the State of California to cause birth defects
or other reproductive harm. For more information go to: www.

NOTICE
LOSS OF BRANCH CIRCUIT POWER / LOSS OF SURGE
SUPPRESSION
• Perform periodic inspection of the surge protective device status
indicator lights as part of the preventative maintenance schedule.
• Promptly replace the surge protective device when an alarm state
exists.
• Use dry contacts to signal an alarm state to the central supervisory
system for unmanned, inaccessible, or critical installations.
• Use multiple surge protective devices to achieve redundancy for critical
applications.
Failure to follow these instructions can result in equipment damage.
At end-of-life conditions, Surge Protective Devices (SPDs) can lose their
ability to suppress power system transient voltage spikes and attempt to
draw excessive current from the line. This SPD is equipped with overcurrent
and overtemperature components that will automatically disconnect the
surge suppression elements from the mains should the surge suppression
elements reach end of life. Tripping of the branch circuit breaker or fuse
feeding the SPD can occur. Mitigate the tripping of the branch circuit breaker
or fuse feeding the SPD by coordinating the surge suppression elements
with the branch circuits.
