INSTALLATION INSTRUCTION 

According to lightning protection zones concept, for installation at LPZ 0_A -1 or higher. It is usually installed in floor distribution-box or ClassⅠmain distribution-box

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

1. The value of FUSE should not be larger than the max.withstand capacity of the Surge Protector'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 Protector.

INSTALLATION STEPS 

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

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

3) Connect conductors, the cross-sectional 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 Protector’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 Protector’s fault appear, electrician should check/replace the Surge Protector.

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.
