■INSTALLATION / INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
LIMITATION APPLICABLE TO M-RESTER
The M-Rester will protect electronics equipment from
damage caused by lightning by absorbing most of the
surge voltages.
However, M-Rester may not be effective against certain
extremely high voltages caused by a direct or almost di-
rect hit by lightning.
M-Rester must be installed according to this installa-
tion/ instruction manual.

POINTS OF CAUTION
■POWER INPUT RATINGS
• Power input ratings are specified by the model number
suffix code. Check the power input voltage for the unit on
the specification label.
AC power: 85 – 264V, 47 – 66 Hz, approx. 2 – 4VA
DC power: 24V ±10% or 85 – 150V, approx. 1.5W
■UNPLUGGING THE UNIT
• Before you remove the unit from its base socket or mount
it, turn off the power supply and the signal for safety.
■ENVIRONMENT
• Indoor use
• When heavy dust or metal particles are present in the
air, install the unit inside proper housing and ventilate it.
• Do not install the unit where it is subjected to continuous
vibration. Do not apply physical impact to the unit.
• Environmental temperature must be within -5 to +55°C
(23 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
• Be sure that the ventilation slits are not covered with ca-
bles, etc.
■WIRING
• Do not install cables (power supply, input and output)
close to noise sources (relay drive cable, high frequency
line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
■AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

ALARM LED
PWR LED
PWR LED (green)
The green LED turns on while the power is supplied;
turns off when the power supply is removed and the
alarm output contact is also turned on.
ALM LED
The tricolor LED turns off, then on in green, amber, and
red according to the unit status.
1) Remains OFF when the power supply is first turned on.
2) Green: The unit has received one or more surges. (The
LED does not turn on when the power is not supplied.)
3) Amber: Replacement is recommended.
4) Red: The life span has ended. Replace the unit immedi-
ately. The alarm contact is turned on.
INSTALLATION
Pull out the body in pressing the clamps located at the top
and bottom of the unit for separating it from the base socket.
■DIN RAIL MOUNTING
Set the base socket so that its DIN rail adapter is at the
bottom. Hung the upper hook at the rear side of base socket
on the DIN rail and push in the lower. When removing the
socket, push down the DIN rail adapter utilizing a minus
screwdriver and pull.

Refer to the drawings in the figure below.
TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the connection diagram label on the side of the unit.
Be sure to make cross-wiring as shown in "GROUNDING". If the protected equipment is not provided with a G terminal,
ground only this unit's G terminal.

CROSSOVER WIRE
GROUNDING
(100 ohms or less)
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.
CHECKING
■WIRING
1) Make sure that wiring is done as instructed in the con-
nection diagram.
2) Power input: Check voltage across the terminal 7 – 8 with
a multimeter.
3) Make sure that Ground terminal 1 is connected to the
metallic housing of protected equipment.
4) Make sure that Ground terminal 1 is grounded to earth.
■ELEMENT MODULE
1) Shortcircuit: Check resistance across the following termi-
nals on the high-resistance range of multimeter (≥100MΩ
or infinite standard).
Terminals (L1) – (L2), (L1) – (G), (L2) – (G)
2) Discharging: Check that discharging occurs across the
same terminals with a 500V DC megger. (Indicator of the
megger must show ≤20MΩ.)
MAINTENANCE
While the ALM LED is green, regular inspections are rec-
ommended.
When it is turned to amber, replacement of the unit is rec-
ommended.
When it is turned to and remain red, replace the unit im-
mediately.
CAUTION
Before replacing the unit, be sure to turn off the power sup-
ply for safety. Other factors such like an alarm system con-
nected
to the line should also be considered.
The life monitoring circuit remain alive due to the inter-
nal backup power even when the external power supply is
removed. The LED is turned off in that case. The backup
power is normally effective for approximately one week de-
pending upon environmental conditions.
