About
The T-SPD L is a circuit board designed for lightning and surge protection. It is mounted in series with the incoming mains supply. In the event of an unnaturally high voltage on the supply, the voltage is led down into the protective ground, and the glass fuse trips. The T-SPD L protects components in the battery backup, thus ensuring high operational reliability.
Installation and Connection
Connect Phase, Neutral, and Ground as shown in the diagram.
Connection Diagram
The diagram illustrates the connection points on the circuit board, which has terminals labeled "PEN L":
- 1: Terminal for connection to the motherboard in the battery backup.
- 2: Terminal for the incoming mains supply.
- 3: Fuse.
