Installation instruction
According to lightning protection zones concept, for installation at LPZ 0A-2 or higher, this surge protector is usually installed in distribution-box or feeder bus of UPS, protecting devices or equipment downstream. Fuse must be installed at the upsteam of the SPD or the lightning protector to make sure that the protected system has double protection. The value of the fuse used in a SPD system should be
conformed to:
- The value of FUSE should not be larger than the max. withstand capacity of the SPD’s backup fuse value.
- 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 SPD.
Installation steps
- Mount the SPD on the 35mm DIN rail.
- Connect conductors, the cross-sectional area of the cable must be larger than 6mm2. The withstand voltage value of the cable is not smaller than AC500V; ensure wiring reliable.
- 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).
- After above, switch on the power supply and turn on the circuit breaker, if the SPD’s window indicate green, this indicates the unit is operating normally.
Regularly inspect the operating status, especially after lightning. Once the fuse or circuit breaker upstream break or the SPD’s window indicates red, electrician should check/replace the SPD Installation diagram:
