Instruction

TSTLP^® 12Vdc ~ 385Vdc Type 2 Surge Protection Device  is designed according to IEC61643-11, EN 61643-11 & GB/T 18802.11. standards for installation at LPZ0_B-1 or higher, protecting voltage equipment from surge.Applied in modular SPD Class (Class C) for DC power supply system & PV DC power supply system such as telecommunication room, microwave, communication room & so on...

♦ Relative T1+2 / T2 SPD for DC / PV Power Supply System

♦ Dimension(mm)

♦ Technical Data 

♦ Features 

1- Combined DC SPD,slim 18mm form factor

2- Pluggable module, easy for installation & maintenance, high discharge capacity,quick response

3- Double thermal disconnector device,providing more reliable protection

4- Multifunctional terminal for connecting conductors & busbars

5-Windows will change to red when fault & also provide remote alarm control at the same time 

♦ INSTALLATION INSTRUCTION

According to lightning protection zones concept, for installation at LPZ 0_B-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 SPD or the lightning protector to make sure that protected system has double protection. The value of the fuse used in a SPD system should be confirmed to:

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

♦ INSTALLATION STEPS

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

2) Mount the SPD 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).

1) After above, switch on the power supply and turn on the circuit breaker,if  the SPD’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 SPD's window indicates red, electrician should check/replace the SPD.

♦ INSTALLATION DIAGRAM FOR REFERENCE

♦ 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.
