Safety precautions:
· When the SPDboxis installed in final system,it must achieve all
therequirements of GB4943 (EN60950,IEC60950) standard;
· The equipment has to be installed by authorized professional
person, before installation, to cut offpowersupply,and prohibit
hot-line work from accidents
Application: ·
Single phase power SPDis suitable forsystempowerprotection,such as
power distributioncabinet,switch cabinet,switch cabinet,AC/DC
distribution board, etc. · Distribution boxwith outdoor input in
the building and each floor · Low voltage(200/380VAC) industrial
and civilpowergrid ·Automationmachine room,power supply panel of
converting station main control room
Features:
·Big discharger current capacity,lowresidualvoltage, quickresponse
· Lowe leakage current and rate of change · Heat isolation
technique, no fire disaster · Apply specigl shock fuse pieces,
withhiahreligbility ·Build-inremote alarm connect point,easy
toremote control · With power indicator to display working
condition ·Equipped with lightning counter,exactly to record
lightning stroke ·Temperature controlprotective circuit, built-in
heat protection. automatic release unit Excellent international
famous core component brand
Installation:
· 35mm slide guide installation way · Connect +/-and ground
terminal of power systemto+/-and ground terminalof SPD, then screw
up the bolts · ground line of SPDto lightning protection
systemground device · After wiring.please checkituntil everything
isgoingwell, toput into operation.
Product maintenance:
·The eauipment has to be installed byauthorized professional
person, before installation,to cut off power supply,and prohibit
hot-line work from accidents · The sectional area of wire must
reach technicaldemands · When the SPD box is installed in final
system,it must achieve all the requirements of GB4943
(EN60950,IEC60950)standard; · The product does notneed to be
maintained specially,but to inspect a fixed period ·
Afterthunderstorm season, it is normal that the indicator window is
red, but to change a new module or total product instantly · Once
there is afailure during systemoperation,please removethe SPD
device at first,if the systemcan operate normally,the deviceis
broken
