4.2.5 REF542plus的接地
如下图所示，连接器X10处的电源板必须
接地至外壳。因此，中间引脚必须连接到
低压室内的接地点。除此之外，HMI控制单元电缆连接的屏蔽也必须分别接地至

为确保EMC（电磁兼容性），外壳必须接地
通过与接地系统的低阻抗电流连接。如中所示
图中，适当的电缆连接，从特定螺钉固定
必须预见低压室中接地系统的外壳。那个
这就是为什么将交织电缆用于接地连接。如果由于安装结构，已经给出了从外壳到接地系统的低阻抗连接，则通过交织
可以不使用电缆。
HMI本地控制单元的外壳也必须接地。可能
如下图所示，特定接地电缆将从HMI本地控制单元的外壳连接到低压隔间的接地系统。

The auxiliary voltage must be in the tolerance range of the power supply module and
have the proper polarity under all operating conditions.
4.2.4.4 Check the tripping and signaling contacts
Conduct this check as shown in the bay documentation.
4.2.4.5 Check the binary inputs
Check the polarity and the voltage value of the binary inputs on the REF542 in accordance with the technical data of the binary inputs.
4.2.5 Grounding of the REF542plus
As can be seen in the following figure, the power supply board at connector X10 must
be grounded to the housing. Therefore the middle pin must be connected to the
grounding point in the LV compartment. Beside that, the shielding of the cable connection to the HMI control unit must also be connected to ground respectively to the
housing.

Figure 4: Grounding of the REF542plus Central Unit housing
To ensure the EMC (Electro Magnetic Compatibility) the housing must be grounded
by a low impedance galvanic connection to the grounding system. As it is shown in
the figure, an appropriate cable connection, which is fixed from a specific screw on
the housing to the grounding system in the LV compartment, must be foreseen. That
is why an interweaving cable is used for the grounding connection. If, due to the installation construction, the low impedance connection from the housing to the grounding system is already given, the additional grounding connection by the interweaving
cable can be abstain from.
The housing of the HMI Local Control Unit must also be grounded too. As can be
seen in the next figure, a specific grounding cable is to be connected from the housing of the HMI Local Control Unit to the grounding system in the LV compartmen.
