Lightning Surge Protectors for

Electronics Equipment M-RESTER

LIGHTNING SURGE PROTECTOR FOR

ANALOG TELECOM LINE USE

(life monitor)

Functions & Features

•Designed specifically to protect telecommunication

equipment from lightning surges entering through

telecommunication line network

•Absorbing surges only without affecting instrumentation

signal

•Life monitor function helps you to decide when you should

replace the M-RESTER; reduces maintenance and prevents

downtime

•LED display and alarm contact output indicate the

degradation and life span of the surge protection circuits

GENERAL SPECIFICATIONS

Construction: Plug-in

Connection

Telecom line: Modular jack or M3.5 screw terminals

(torque 0.8 N·m);

Line screw terminal connection must be handled by

qualified personnel.

Ground: M3.5 screw terminals (torque 0.8 N·m)

Modular jack cord: 6-pole, 2-core

Screw terminal: Nickel-plated steel

Housing material: Flame-resistant resin (black)

Alarm indicators

Power: The green LED turns on while the power is

supplied.

Alarm: Tricolor LED (green/amber/red)

•Remains off when the power supply is first turned on.

•Green: The unit has received one or more surges.

•Amber: Replacement is recommended.

•Red: The life span has ended.

Life time judged: When the number of discharges

of the discharge element reaches the expected life span.

Alarm contact: The N.C. contact is on when the life span of

the discharge elements has ended and/or when the power

supply is removed.
