■
Output module
You must provide a short-circuit protection fuse in the load power supply circuit of the output module. Use fuses
with the correct load rating. Using the wrong fuse might result in damage to the PCB or housing if the load short-
circuits.

Grounding
●
Panel grounding specifications
The PCs panel that incorporates the S10VE must be welded to the steel frame of a building that provides at
least
class D grounding with the ground resistance of 100Ω or less.
Conditions for grounding to the steel frame of a building
- The steel frame is welded together
- The grounding between the earth and the steel frame meets the criteria for class D
If this is not achievable, ground the PCs panel by connecting it to a grounding rod driven into the earth. This
provides a low grounding resistance that prevents surrounding noise from entering the PCs.
