(torque 0.8 N·m);

Lightning Surge Protectors for

Electronics Equipment M-RESTER

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

LIGHTNING SURGE PROTECTOR FOR

Screw terminal: Nickel-plated steel

ANALOG TELECOM LINE USE

(life monitor)

Housing material: Flame-resistant resin (black)

Alarm indicators

Functions & Features

Power: The green LED turns on while the power is

supplied.

•Designed specifically to protect telecommunication

equipment from lightning surges entering through

telecommunication line network

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.

•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

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.

•LED display and alarm contact output indicate the

degradation and life span of the surge protection circuits

CROSSOVER WIRE

A crossover wire between M-RESTER ground and ground or metallic

housing of equipment is required for protection.

If the protected equipment has no ground terminal, ground the

M-RESTER only.
