SPD200K/300K
Maintenance and Troubleshooting
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E,
CSA Z462 or NOM-029-STPS.
•
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.
•
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.
Preventative Maintenance
Inspect the SPD periodically to help maintain system performance and continued transient voltage surge
suppression. Periodically check the state of the diagnostic display panel LED status indicators. Routinely use
the built-in diagnostics to inspect for inoperative modules.
Troubleshooting
This surge protector has little to troubleshoot. If a phase LED in extinguished or the service light is on please
contact us.
For application questions, contact us at 1-800-377-4384 or [email protected].
Replacement Parts
The module is field replaceable. Deenergize SPD, confirm with appropriate measurement equipment and
discharge internal capacitance to ground. Mark locations and carefully disconnect diagnostic cables, dry
contact connections, phase conductors, unplug parallel connections on SPD200K/300K models, etc. Reinstall
in reverse order.
There are no user serviceable parts inside the module. We strongly recommend against disassembly.
Modules may be returned to the factory for factory service, qualification and return. Please contact us
at 1-800-377-4384 for assistance.
