INSTALLATION INSTRUCTION 

1. This BNC Surge Arrester is connected in series to the protected device.

2. Mount the BNC Surge Arrester on 35 mm DIN rail.

3. The out terminal should be connected to the protected devices.

4. BNC Surge Arrester's earthing terminal must be connected to nearby earthing Busbar or the metal earthing enclosure of protected device.

Regularly inspect the operating status, especially after lightning, once the communication is off, electrician should check/replace the BNC Surge Arrester.

INSTALLATION DIAGRAM

WARNING:

 1, The device must be installed by electrically skilled person, conforming to national standards and safety regulations.

2, It is recommended that installation should be done under power off condition.
