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.

■ SELECTING LOOP DISCONNECT FUSE
• Specify ‘Loop disconnect fuse’ type when multiple transmitters are connected to single power bus.
• Loop disconnect fuse is used to separate a transmitter loop from the power bus when it fails in the shortcircuit mode.

*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.
