安装说明/INSTALLATION INSTRUCTIONS

1.只能由合格的电工进行安装!

2.在进行任何电气连接之前,确保电气服务已断开。

3.支路保护按国家和地方规范要求设置检查机构的报告。

4.按要求布线,并按照本表和装置上的接线图固定到端子上。

5.传感器适合安装在600Vac线路上。

6.为防止与带电电路接触,当安装在裸母线上时,要求传感器安装在需要使用工具进入的外壳中。当安装在绝缘电缆上时不需要第二个外壳的电缆。

1. Installation should be performed by qualifi ed electricians only!

2. Make sure electrical service is disconnected before making any electrical connections.

3. Branch circuit protection is required to be provided in accordance with the National and Local codes of the inspection authority.

4. Route wires as required and secure to terminals per connection diagram on this sheet and on the unit.

5. Transducers are suitable for installation on 600Vac lines.

6. To prevent contact with live circuits, when installed on a bare bus bar, the transducer is required to be mounted in an enclosure that requires the use of a tool for access. When installed on an insulated cable this second enclosure is not required.

 

 

操作说明/OPERATING INSTRUCTIONS

4.最高相对湿度80%,温度最高31ºC,线性下降至50% 40℃时的相对湿度。

5.最大工作温度范围为-20°C60°C

1. This unit is intended for indoor use at altitudes up to 2000 meters.

2. Transient overvoltages according to Installation Category (overvoltage) II, Pollution Degree 2.

3. If cleaning of the exterior surface is necessary, de-energize all services of supply (both measuring and instrument power circuits) and brush with a soft brush or blow off with low-pressure air. Use appropriate eye protection. Not suitable for hose-down cleaning.

4. Maximum relative humidity 80 percent for temperatures up to 31ºC decreasing linearly to 50 percent relative humidity at 40ºC.

5. Maximum operating temperature range is -20°C to 60°C.
