♦ MAIN CHARACTER
1, Standard single chip structure, pluggable
2, Consist of varistor and thermal disconnection device
3, High discharge capacity, quick response
4, Double thermal disconnection devices, provide more reliable protection
5, Multifunctional terminals for connection of conductors and busbars
6, Green windows will change to Red and Green Light will Change to Red when fault occurs
♦ INSTALLATION INSTRUCTION
According to lightning protection zones concept, for installation at LPZ 0B-1 or higher. This surge arrester 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 Arrester or the lightning arrester to make sure that protected system has double protection. The value of the fuse used in a Surge Arrester system should be confirmed to:
1. The value of FUSE should not be larger than the max.withstand capacity of the Surge Arrester’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 Arrester.
♦ INSTALLATION STEPS
1) Check the product for integrity of the package; make sure the product WINDOW & LIGHT indicate green.
2) Mount the Surge Arrester on the 35mm DIN rail.
3) Connect conductors, the cross-section area of cable must be larger than 6mm2 . 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 Arrester’s window does not appear red,(and if the Surge Arrester 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 Arrester’s window indicates red, electrician should check/replace the Surge Arrester.
♦ Installation Diagram (4+0)
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.
