6.1 Operating environment
For details about the operating environment of the S10VE system see
Chapter 3. Specifications
.
6.2 Grounding
The PCs panel that incorporates the S10VE must be welded to the steel frame of a building that provides class D
grounding with the ground resistance of 100
Ω or less. If this is not achievable, ground the panel by connecting it
to a grounding rod driven into the earth.
Figure 6-1 Example of panel grounding
Notice
●
If the environment does not meet the conditions for grounding to the steel frame of the building, drive a
grounding rod in the earth near the PCs panel that provides a low grounding resistance. This prevents
surrounding noise from entering the PCs and prevents equipment from failing or malfunctioning.
Conditions for grounding to steel frame of building:
- The steel frame is welded together.
- The grounding between the earth and the steel frame meets the criteria for class D.
- To prevent AC current from entering the grounding point of the PCs panel, the grounding point
connects to a different main line from the AC panel, separated by a distance of at least 15 m.
