Installing the SIEMENS FS140 Whole House Surge Protector involves several steps to ensure effective surge protection for your home. Here's a detailed guide:
Preparation: Before you begin, familiarize yourself with National and Local electrical codes (NEC Article 285 and UL 1449) pertaining to surge protective devices (SPDs). Verify that your system's voltage matches the SPD's voltage (e.g., a 120V SPD will not work on a 240V or 277V system). The ideal mounting location for the SPD is as close as possible to the electrical panel or equipment, minimizing lead lengths.
Location and Mounting: Decide on the mounting location. If the installation is outdoors, or in a location exposed to the elements, consider that weather-resistant equipment might be needed. If using the optional Flush Mount Kit, follow its specific instructions before proceeding.
Power Disconnection: Safety first! Turn off the power supply to the electrical panel or source and confirm that it is de-energized before you start any work.
Positioning and Placement: Determine the placement of the SIEMENS FS140, ensuring that the indicators are easily visible. If you are using a Flush Mount Kit, install it according to its included instructions.
Mounting the SIEMENS FS140: Remove an appropriately sized knockout from the panel and secure the SIEMENS FS140. For outdoor or weather-exposed installations, you may need additional sealing, which is not included.
Conductor Connections: Connect the conductors carefully, making them as short and straight as possible. Use a breaker position that is close to both the SPD and the panel's neutral and ground connections. Be sure to label or mark the conductors correctly (neutral: white, ground: green, energized: black).
Grounding: Ensure proper grounding, as required by the National Electrical Code (NEC). Verify that the system is properly bonded and is free from any potential hazards or faults before powering the SPD.
Energizing and Testing: After all connections are made, restore power to the system. Check the green LED indicators on the SIEMENS FS140 to confirm proper operation. If any phase LED does not illuminate, immediately disconnect power, check all connections, and retest. If the issue persists, consult the SIEMENS FS140 Whole House Surge Protection Instruction Manual or contact Siemens Technical Support at 1-888-333-3545.
Audible Alarm: The SIEMENS FS140 has an audible alarm that will activate in the event of an alarm condition, indicating a potential issue with the SPD. Disconnecting power to the SPD will silence the alarm.
It is strongly recommended to consult the SIEMENS FS140 Whole House Surge Protection Instruction Manual for detailed specifications, safety guidelines, and additional precautions before commencing the installation.
