4. WIRING DIAGRAM

5.Main Features:

l  Use Y-shaped connection, Full mode protection of the L+-L-/PE;

l  Use the temperature control circuit break protection technology,to avoid the accident;

l   With the remote alarm contact signal, convenient to remote monitoring of the system;

l   The module has normal and fault indication, with fast response speed and low residual voltage.

6.Installation Method and Attentions

1) Wiring as shown in Figure;

2) The connecting lead shall use many strands of copper wires of more than 6mm², and the earth wire shall use many strands of copper wires of more than 10mm². The connecting wire shall be as short, straight and coarse as possible. Grounding Resistance should be no less than 4Ω;

3) The front of lightning arrester shall be connected with proper fuse in series or be opened;

4) The power supply must be cut off while conducting the installation. It is prohibited to conduct the operation with the charge. The connecting lead must conform to the requirement;

5) After completing the installation, the lightning protection module shall be inserted tightly and inspected;

6) When there is RED for the fault indicator of the lightning arrester module (warning signal of remote-signaling port), it indicates that the lightning protection module has degraded and shall be replaced;

7) The SPD needn't special maintenance, but only check the connection and indicating state periodically.
