DESCRIPTIONS
■ SELECTING SHIELD TERMINAL TYPE
• The surge protector has a dedicated shield terminal effective for easy shield wiring and surge protection.
• Review the shield method (grounding, non-grounding, connecting to SG, etc.) required by the protected device or system.
• There is no electrical effect to the shield by installing the surge protector, but an appropriate shield terminal type must be
selected to suit user applications.
• Refer to the flow chart below to choose.

*1. Oxide film on the surface of an aluminium rail may lower the electric conductivity between this module and the ground.
Use a steel or copper rail.
*2. Be sure to ground the DIN rail. Recommended grounding resistance ≤100Ω
*3. Cross-wire between the DIN rail and the metal housing of the protected device to equalize the earth potential.
Ground only the surge protector when the protected device has no ground terminal.
*4. Shield wiring method is an example. Proceed according to the system requirements.
