SST-2000A/H的安装
装置的安装
使用标准手工具安装SST-2000A-/H；一般使用标准操作安装在控制面板或密封装置上。
关于电接插件
内部通用标准 隔离
警告; 使用DC电源时避免造成损坏
1.如果负荷不引用SST-2000A-/H相同的通用标准，安装在4-20ma输出电流和负荷电流环路隔离装置。
信号输入(低端，末端6) 对辅助生产(低端，末端7)通用，通常使用在直流电源(末端4)和低端(末端9)主要的比例输出装置上。 继电器触点常常需要进行分隔；
当使用交流电源：所以的电路必须与内置供应变压器和电源线隔离；
当使用直流电源：变送器输出不与直流电源隔离；任何变送器驱动的负荷(即记录器,,控制器,等)必须有如直流电源阴极的相同。 如果负荷不引用SST-2000相同的通用标准，安装在4-20ma输出电流和负荷电流环路隔离装置。
图 2-1 电气装线画
使用保护电缆：将没有接地的保护装置和末端4 连结起来。
回路供电和继电器连接装置是分开的，并且对线路重新进行设置行防止电噪音干扰。
终端4，6，7，和9与内部线路连接在一起，除非装置带有信号隔离变压器。这样；终端6将被隔离

Mounting the unit
The SST-2000A/H is installed using standard hand tools. It is generally mounted in a panel or enclosure using standard practices.
About Electrical Connections
Internal Commons, Isolation
WARNING: AVOID DAMAGE WHEN DC-POWERED
Install a current loop isolator between the 4-20 ma output and the load if the load does not reference the same common as the SST-2000A/H.
Signal input (low side, terminal 6) is common to the auxiliary output (low side, terminal 7), to the dc supply (terminal 4), and to the main proportional output low side (terminal 9). Relay contacts are always isolated
When powered with ac: all circuitry is isolated from the power line by the built-in supply transformer
When powered with dc: the transmitter output is not isolated from the dc power source. Any load driven by the transmitter (i.e. recorder, controller, etc.) must have the same common as the negative side of the dc supply. Install a current loop isolator between the 4-20 mA output and the load if the load does not reference the same common as the SST-2000.
Fig. 2-1 Electrical Connection Drawing.
Use shielded cable: connect ungrounded shield to terminal 4.
Route power line and relay connections separate from signal meter and reset lines to prevent electrical noise interference.
Terminals 4, 6, 7, and 9 are internally tied together to circuit common unless unit has signal isolation transformer. In that case, terminal 6 is isolated. ® 0 ® ®
