*1. Leave Terminal A when the shielded twisted-pair cable is not provided.
*2. Leave Terminal 1 when the protected device has no SG (Signal Ground) terminal.
*3. Cross wire to the surge protector’s G terminal when grounding the shield wire.
*4. Cross-over wire between G terminals of the surge protector and the protected device is required.
Ground only the surge protector if the protected device has no G terminal.
Example: Each SG terminal is connected with triplex cable

*1. Provide electrical insulation with insulating tape and the like so that the live part is not exposed,
as over voltage may generate on the shield wire.
*2. Cross wire to the surge protector’s G terminal when grounding the shield wire.
*3. Cross-over wire between G terminals of the surge protector and the protected device is required.
Ground only the surge protector if the protected device has no G terminal.

CROSSOVER WIRE
A crossover wire between M-RESTER ground and the ground or
metallic housing of the equipment is required for protection.
If the protected equipment has no ground terminal, ground the
M-RESTER only.
When the M-RESTER is mounted with DIN Rail Mounting Adapter,
connect the grounding wire to the mounting screw of the M-RESTER.
