FIELD
The M-RESTER must be connected with its terminals S1 and S2 faced on power source side
in order that the fuses would be blown in case of shortcircuit of the discharge element.

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.
