CROSSOVER WIRE

GROUNDING

(100 ohms or less)

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.
