屏蔽机柜照片和注意事项

旺旺

●安装调试

■使用环境：环境温度- 25℃——+70℃ 相对湿度 ≯85% 防止与腐蚀性物质和气体相接触；

■设备移至确定位置，保持平稳，将四只定位螺栓调下，防止机柜使用时移位；

■屏蔽柜应可靠接地，接地电阻应≤1Ω，接地桩引出端子与屏蔽柜接地螺栓搭接地电阻应≤0.1Ω。

■通电前必须接地；接地时电源插座前不能有漏电保安器，如本栋建筑物接电系统有漏电保安器，
则应在漏电保安器前段单独拉一路电源来给本机柜供电。 因滤波器是电容电感组成，电容有充放作用，
否则在插座前加隔离变压器或专用电源插座；

■不接地时屏蔽柜对地电阻应大于1000Ω。

■安装进入机柜的光纤线和屏蔽铜缆必须要经过屏蔽柜后面的波导管孔
（具体数量应在订购机柜时确定，并在生产时做好）.

■同时响应的线缆上的屏蔽网丝和金属线应截断,并从屏蔽柜前内,外两方面,
把截断的屏蔽网丝和金属线固定在波导管两端的金属锣口中.使之通过屏蔽柜良好接地.达到屏蔽效果.

■屏蔽柜的波导管的数量应按客户的实际需求在生产时订制安装.一根线缆进入屏蔽柜需要一个波导管.并需要区分光纤和屏蔽铜缆.

建筑中的弱电主要有两类：一类是国家规定的安全电压等级及控制电压等低电压电能，有交流与直流之分，如24V直流控制电源，或应急照明灯备用电源。另一类是载有语音、图像、数据等信息的信息源，如电话、电视、计算机的信息。 　　智能化系统为建筑设备监控系统、安全防范系统、通讯网络系统、信息网络系统、火灾自动报警及消防联动等系统，以集中监视、控制和管理为目的构成的综合系统；家庭内各种数据采集、控制、管理及通讯的控制或网络系统等线路，则称为智能化线路（也就是家庭装修中所说的弱电）。

Congrats, you made it! Of 重庆团购 course, feel free to mix and

match up these strategies with your own to make 重庆二手交易 it a

style you enjoy.
Remember, there is no cookie-cutter way to power level but you can create your own by testing,

testing, and more testing. Be sure to bookmark this page and check out the other guides...
This guide will show you the absolute 重庆二手电脑 fastest way to

get to level 49, but only good for the alliance
as they are the 重庆二手手机 only ones that can do this quest.
When you hit level 40 head off to the Hinterlands to the Wildhammer Keep and talk to Fraggar

Thundermantle to get the Troll Necklace Bounty quest. The best part about this quest is that it is

repeatable, meaning you can final fantasy leveling do it over and

over again. Granted the exp reward does drop after the
initial final fantasy gold turn in but

an extra 390 exp while grinding always helps!
After you get this quest you will want to head east to Zun'watha. At that location you will find a

camp of trolls. Start ff14 gold on one side and

just go in a circle killing all the trolls. They have a
fast respawn rate ffxiv power leveling so when you get

around the camp once they will be respawned so you don't have to stop!
Using a hunter I found out I was using a lot of mana so you might want to conserve mana when you can

to keep going so you will ff14 power leveling not have to

stop a whole lot. Don't worry you will stop a few
times when first ffxiv power leveling doing this but it gets easier

and better as you go.
