APC MODULAR PANEL PRODUCTS Surge Protective Device (SPD)

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.

OPERATION AND The SPD display panel shows the status of the modules with diagnostically LED STATUS INDICATORS controlled green/red LED’s. If a unit is operating correctly, all the phase

LED’s will be illuminated green. To test the integrity of the diagnostics for each phase, push the button below the phase LED’s on the diagnostic display. The green LED will turn red and the alarm will sound, if the alarm is enabled. Releasing the test button will complete the test; the red LED will turn green and the alarm will shut off.

If an inoperable condition occurs on any phase, the audible alarm will enable and the corresponding phase LED on the diagnostic display panel will illuminate red. This indicates that the device needs service by a qualified electrical personnel. The audible alarm can be silenced by pressing the alarm enable/disable button until a qualified person is able to evaluate and service the SPD. If the alarm is silenced the phase LED will remain red. The red phase LED will continue to be illuminated until the inoperative condition is cleared.

On wye and split phase configuration SPD modules (see Figure 7), if the left green LED is not lit, it indicates a loss of suppression from line-to- ground for that phase. If the right green LED is not lit, it indicates a loss of suppression from line-to-neutral for that phase. If both green LEDs are not lit and the diagnostic display panel has power, then power has been lost to that phase or module is bad and should be replaced.

Figure 7: SPD Module LEDs (Wye and Split Phase configurations)

Left green LED lit: Unit is operating correctly

Left green LED not lit: Loss of surge suppres- sion from L·G

Right green LED lit:

Unit is operating correctly

Right green LED not lit: Loss of surge suppression from L·N

When power is applied to the SPD and one or more of the display LED’s are red or not illuminated then the module should be replaced. Refer to

“Maintenance and Troubleshooting” on page 19 for proper troubleshooting procedures.
