♦ MAIN CHARACTER 

1, High discharge capacity, quick response

2, Consist of varistor and thermal disconnection device

3, Double terminals for parallel or series (V-shape) connection

4, Multifunctional connection for conductors and busbars

5, Green windows will change to Red when fault occurs, and Remote Alarm Terminal available. 

♦ INSTALLATION INSTRUCTION

According to lightning protection zones concept, for installation at LPZ 0 -1 or higher. This surge protection is usually installed in distribution-box or feeder bus of UPS, protecting devices or equipment downstream. Fuse must be installed at the upstream of the Surge Protection or the lightning arrester to make sure that the protected system has double protection. The value of the fuse used in a Surge Protection system should be conformed 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.

3. 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 indicates green.

2) Mount the Surge Protection 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 Protection’s window does not appear red,(and if the Surge Protection with lights,3 green lights display HIGH GREEN and another red light doesn’t display HIGH 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 and 1 light display HIGH RED, electrician should check/replace the Surge Protection.

♦ 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.
