Maintenance and Troubleshooting
The Siemens FS140 is designed for minimal maintenance. Its primary function is to protect your home from surges, and its status indicators provide clear guidance on its condition.
Maintenance
Regular maintenance is limited to observing the status indicators. No user-serviceable parts are inside the unit. Do not attempt to open or repair the device.
Troubleshooting
Troubleshooting primarily involves interpreting the device's status signals:
- Audible Alarm with Extinguished Green LEDs and Flashing Red Service Light: This indicates the surge protection module has reached its end of life and needs replacement. The device has successfully protected your home from a significant surge. Contact a qualified electrician or Siemens customer support for replacement options.
- Audible Alarm with Lit Green LEDs and Flashing Red Service Light: This signals a potential issue with your electrical system's neutral to ground bond. While the surge protection may still be active, this condition represents a safety hazard. Immediately contact a qualified electrician to inspect and correct your home's electrical wiring.
- No Lights or Alarm: If the device shows no signs of power (no green LEDs, no alarm), ensure it is properly connected to the electrical system. If connections are secure and power is present at the panel, the device may be faulty or require replacement. Consult a qualified electrician.
