Lightning Surge Protectors for
Electronics Equipment M-RESTER
GENERAL SPECIFICATIONS
Construction: Plug-in
Connection: M4 screw terminals (torque 0.8 N·m)
Screw terminal: Nickel-plated steel
Housing material: Flame-resistant resin (black)
LIGHTNING SURGE PROTECTOR FOR EC-CABLE USE
Functions & Features
• Designed specifically for M-System’s 32-point
Transmission System EC-CABLE
INSTALLATION
Operating temperature: -5 to +55°C (23 to 131°F)
Operating humidity: 30 to 90 %RH (non-condensing)
Mounting: Surface or DIN rail
• Protects the transmitter model ECT and the receiver ECR
from lightning surges entering through the twisted-pair
cables connecting the both modules
Weight:
• Applicable to transmission systems by current loops
• Absorbs surges only without affecting instrumentation
signal
120 g (0.26 lb), standard

(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.
