3 MODEL: MDTC 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.
