Siemens QSPD2A035B BoltShield Indoor Surge Protective Device Instruction Manual

1. Product Overview

The Siemens QSPD2A035B BoltShield Indoor Surge Protective Device (SPD) is designed to offer protection against both external and internal electrical surges. Optimal protection is achieved when the SPD is installed as close as possible to the building's main electrical distribution system. This device provides an economical and straightforward solution for integrating surge protection into most Siemens load centers, facilitating comprehensive facility protection.

• Compatible with existing Siemens load centers.
• Provides 35kA surge current protection per phase.
• Features green/red mechanical visual indicators to display protection status.
• Designed for quick installation by plugging directly into the load center bus.

2. Safety Information

WARNING: Installation of this device involves working with high voltage electricity. Improper installation can result in serious injury or death. It is strongly recommended that installation be performed by a qualified electrician. Always ensure the main power supply to the electrical panel is turned OFF before beginning any installation or maintenance work.

• Always disconnect power at the main breaker before opening the electrical panel.
• Use appropriate personal protective equipment (PPE), including insulated gloves and safety glasses.
• Verify that power is off using a voltage tester before touching any wires or components.
• Follow all local electrical codes and regulations.

3. Setup and Installation

The Siemens QSPD2A035B is designed for straightforward installation into compatible Siemens load centers. It occupies two breaker slots and connects directly to the bus bars.

1. Prepare the Panel: Ensure the main power to the electrical panel is completely disconnected. Remove the panel cover.
2. Identify Slots: Locate two adjacent vacant slots in your Siemens load center. For optimal protection, install the SPD as close to the main breaker as possible.
3. Install the SPD: Align the SPD with the bus bars in the chosen slots. Apply firm, even pressure to plug the device directly into the load center bus. It should snap securely into place, similar to a standard two-pole circuit breaker.
4. Connect Neutral Wire: The SPD includes a white pigtail wire. Connect this wire to the neutral bus bar within the electrical panel. Ensure a secure connection.
5. Verify Installation: Double-check all connections for tightness and proper seating.
6. Restore Power: Replace the panel cover. Restore power to the electrical panel by turning the main breaker back ON.

4. Operating Instructions

The Siemens QSPD2A035B features mechanical visual indicators on its front face to provide immediate status feedback. These are not LED lights but mechanical flags.

• Green Indicator: When the indicators display GREEN, the device is fully operational and providing surge protection.
• Red Indicator: If one or both indicators display RED, it signifies that the device has experienced a surge event and is no longer providing protection. The unit must be replaced.

5. Maintenance

The Siemens QSPD2A035B requires minimal maintenance. The primary maintenance task is to periodically check the visual indicators on the front of the device.

• Regular Inspection: Periodically inspect the device's visual indicators. A monthly check is recommended.
• Replacement: If any indicator shows RED, the SPD has absorbed a surge and is no longer functional. It must be replaced immediately to restore surge protection to your electrical system.

6. Troubleshooting

The primary troubleshooting scenario for the Siemens QSPD2A035B involves its visual indicators.

• Indicators are RED: If the visual indicators are red, the device has successfully protected your system from a surge. It is now expended and requires replacement. Contact a qualified electrician for replacement.
• No Indicators Visible (or not green after installation): Ensure the device is correctly installed and fully seated in the bus bar. Confirm that the neutral wire is securely connected. Verify that power has been restored to the panel. If issues persist, consult a qualified electrician. Note that these are mechanical flags, not LEDs, and will only show green when active or red when expended.
