INSTALLATION INSTRUCTION 

This surge arrester is usually in stalled in distribution-box,protecting wind turbine and so on. For TN system, usually use 3P or 3+1(PE/N) pieces of this product.

Fuse must be installed at the upstream of the Surge Protection or the lightning arrester to make sure that protected system has double protection. The value of the fuse used in a Surge Protection system should be confirmed to:

1. The value of FUSE should not be larger than the max.withstand capacity of the Surge Protection's backup fuse value.

2. Under the status of the max. current in the power supply & close loop circuit available current, the fuse should be able to disconnect when overloaded or short-circuited.

Take 1 & 2 into consideration, the fuse should be as large as possible to allow the maximum surge discharge of Surge Protection.

INSTALLATION STEPS 

1) Check the product for integrity of the package; make sure the product window indicate green.

2) Mount the Surge Protection on the 35mm DIN rail.

3) Connect conductors, the cross-section area of cable must be larger than 16mm² . The withstand voltage value of cable is not smaller than AC500V; ensure wiring reliable.

4) If need remote alarm, it should be connected signal lines to remote signal terminal 1 and 2, or 2 and 3 (When normal,1 and 2 open, 2 and 3 close; when fault, the state is reversed).

5) After above, switch on the power supply and turn on the circuit breaker, if the Surge Protection’s window does not appear red, this indicates the unit is operating normally.

Regularly inspect the operating status, especially after lightning. Once the fuse upstream break, or the Surge Protection's window indicates red, electrician should check/replace the Surge Protection. 

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.
