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.

Inspect the SPD periodically to hlep 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.

The ASCO 460/465/480/485 surge protector has little to troubleshoot. If a

phase LED in extinguished or the service light is on please contact ASCO

Power Technologies. For application questions, contact the ASCO Power

Technologies Technical Assistance Group at (800) 237-4567 or surgetech@

ascopower.com

The module(s) 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

between modules. Depending on model, module may be bolted to backplane

or the backplane may be part of the module assembly. Remove module/

backplane. 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 the factory at (800)

237-4567 for assistance.
