*1. Applicable devices: M-System’s MsysNet or SIN-NET devices which employ RS-422/485 communication standards.
*2. Recommended cable length between the surge protector and the protected device: 1 meter at the maximum
*3. No connection is required if the protected device has no shield terminal.
*4. Cross wire between the protected device’s FG terminal and the surge protector’s G terminal, and ground to the earth
at the surge protector side.
Ground only the surge protector if the protected device has no FG terminal.

GROUNDING
(100 ohms or less)
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.
