操作面板的安装夹不能提供安全接地
面板和设备机柜之间的连接。
2.在操作面板的快速连接底座和
面板机箱。
3.在面板底盘和
门上近的接地点。
4.在门和设备之间连接一条结实但短的接地编织线

6.铁氧体磁芯抑制对24 V馈线的干扰。
围绕铁氧体磁芯旋转2圈可提供4倍于1圈的抑制。
围绕铁氧体磁芯旋转3圈可提供9倍于1圈的抑制。
面板中的以太网连接
1.在一些以太网工业装置中,RJ45触点的屏蔽连接到
底盘通过电容器。
接地线应短,导线应具有大面积。

Au 2.5 mm2 wire between the operator panel’s quick-connect plinth and
the panel chassis.
3. Connect a 6 or 4 mm2 wire or grounding braid between the panel’s chassis and
the closest grounding point on the door.
4. Connect a strong but short grounding braid between the door and the device
cabinet.
5. Twist the cables onto the 24 V DC feed.

6. A ferrite core suppresses disturbances to the 24 V feed.
2 turns around the ferrite core provide 4 times the suppression of 1 turn.
3 turns around the ferrite core provide 9 times the suppression of 1 turn.
Ethernet Connection in the Panel
1. In some industrial units for Ethernet, the RJ45 contact’s shield is connected to
the chassis via a capacitor.
The grounding wires should be short and the conductor should have a large area.
A long, thin grounding wire has a very high impedance (resistance) at high
frequencies and will not guide disturbances to the ground.
Multi-wire conductors are better than single wire conductors with the same area.
A braided conductor wire with the same area is even better.
The best is a short, thick grounding braid.
