■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 cer-
tain extremely high voltages caused by a direct or almost
direct hit by lightning.
M-RESTER must be installed according to this installa-
tion / instruction manual.
POINTS OF CAUTION
■ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the
air, install the surge protector inside proper housing with
sufficient ventilation.
• Do not install the surge protector where it is subjected to
continuous vibration. Do not subject the unit to physical
impact.
• Environmental temperature must be within -25 to +85°C
(-13 to +185°F) with relative humidity within 10 to 90%
RH in order to ensure adequate life span and operation.
• This unit can be earthed via a DIN rail. Oxide film on the
surface of an aluminum rail may lower the electric con-
ductivity between this module and the ground. When this
unit is earthed via a DIN rail, use a steel or copper rail.
• Steel rails may be coated with thin oxide film. Discharg-
ing surge current may produce sparks with the film.
However, this does not affect the surge protection. If you
need to avoid sparks, prior to mounting on the DIN rail,
remove the film by a wire brush.
• Single mount DIN rail for option code ‘/DR’ is made of alu-
minum. Connect to ground with ground terminal when
this DIN rail is used.
■AND ....
• We recommend that you keep spare surge protectors so
that you can replace them when necessary.
• Lightning surge can enter not only through signal lines
but also through power supply lines. We recommend that
you also use the surge protectors for power line for suf-
ficient protection.

■WIRING INSTRUCTIONS
Applicable wire size range for euro type connector terminal
of communication is as shown below.
• Applicable wire size
Solid: 0.2 to 2.5 mm2(0.55 to 1.75 dia.)
Stranded: 0.2 to 2.5 mm2
Tinning wire ends may cause contact failure
and therefore is not recommended.
Ferruled: 0.2 to 1.5 mm2(0.55 to 1.35 dia.)
The following Phoenix Contact terminals are recommended:
AI 0.25-8YE 0.2 to 0.25 mm2
AI 0.34-8TQ 0.25 to 0.34 mm2
AI 0.5-8WH 0.34 to 0.5 mm2
AI 0.75-8GY 0.5 to 0.75 mm2
AI 1.0-8RD 0.75 to 1.0 mm2
AI 1.5-8BK 1.0 to 1.5 mm2
• Expose wire conductors by 8 mm (0.31”).

MAINTENANCE
Check surge protectors periodically. Many cases of light-
ning are ignored, and even lightning at a far distance often
causes inductive surges.
We recommend that you check your surge protector about
twice a year, before and after the rainy season. Check
whenever you experience a strong lightning occurrence.
Checking procedure is explained in the following:
■CHECKING
1. WIRING
• Make sure that wiring is done as instructed in the con-
nection diagram.
2. DISCHARGE ELEMENT
Approximate checking can be conducted as following.
• Shortcircuit test
1) Remove all cables connected to the MDCAT-SPE.
2) Remove also the shortcircuit bar.
3) Check resistance across the following terminals on the
high resistance range of multimeter and confirm no con-
duction. (The meter will indicate the same value as it
will show when these terminals are open.)
(1)-G, (2)-G, (3)-G
4) Then, apply ±60V DC across the following terminals and
measure leakage current to show ≤ 5µA. If a voltage gen-
erator is not available, check resistance with a multim-
eter and confirm no conduction. (Use of a voltage genera-
tor is strongly recommended.)
• Discharging test
1) Check that discharging occurs across the following termi-
nals with a ±500V DC 1000 MΩ insulation tester.
(The tester shows ≤ 20MΩ.)
(1)-G, (2)-G, (3)-G
