| The basic requirement of grounding is that the grounding |
|
| resistance should be little. During the engineering design, low- |
|
| resistance grounding materials should be applied with sufficient |
|
| length, width and thickness to ensure that 3P@C 4450E meets |
|
| the grounding requirements. Ground piles can be buried deeply |
|
| under the ground to form a flat surface there, so as to ensure low |
|
| resistance for various frequencies. As the type of soil impacts the |
| prompt | grounding resistance most, chemical agents |
|
| agents) can be applied around the ground pile to reduce |
|
| resistance for areas where the soil conditions are poor. |
|
| Furthermore, the temperature and humidity of soil also have |
|
| impact on the grounding resistance and this should also be |
|
| considered during the engineering design. |
3.1.7.Anti-interference Requirements
Any interfering sources from the equipment or outside the applied system may affect the equipment in the capacitance coupling, inductance coupling, electromagnetic wave radiation, common resistance (including the grounding system) and the conduction mode of conducting wire (power supply line, signaling line and output wire). For this reason, note that:
Take effective power
Do not combine the working ground of 3P@C 4450E with the grounding device or the lightning grounding device of the power equipment but keep the distance between them as far as possible.
Keep far away from any
Take electromagnetic shielding measures when necessary.
3.1.8.Other Requirements
The indoor should be bright enough for operation, preferably 500 ~ 750 lumen/m2.
The equipment room should be attended by designated persons or have other
The water supply and draining systems of the equipment room should be designed in accordance with the normal water consumption and fire fighting regulations, and sufficient fire protection devices should be equipped.
