INSTALLATION / INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, installation, and basic maintenance
procedure.
LIMITATION APPLICABLE TO MATP
The MATP will protect electronics equipment from dam-
age caused by induced lightning by absorbing most of
the surge voltages.
However, MATP may not be effective against certain
extremely high voltages exceeding its discharge current
capacity (20 kA or 40 kA @ 8/20 µsec. waveform) caused
by a direct or almost direct hit by lightning.
The MATP must be installed according to this installa-
tion / instruction manual.
PERFORMANCE
Max. continuous operating voltage (Uc): 600 V DC
Discharge voltage: (Line to earth) 600 V DC
Maximum surge voltage: 2.5 kV
Maximum (Imax) and Nominal (In) discharge current: (8/
20 μsec.)
• MATP-600Mx: 20 kA (Imax), 10 kA (In)
• MATP-600Hx: 40 kA (Imax), 20 kA (In)
Response time: ≤ 4 nsec.
Leakage current: ≤ 1 mA
Insulation resistance: ≥ 100 MΩ with 500 V DC (line to
alarm output)
Dielectric strength: 2000 V AC @ 1 minute (line to alarm
output)
POINTS OF CAUTION
■
INSTALLATION
• DANGER!
DO NOT install the MATP at the point common to an
external lightning protection device such as a lightning
rod. The MATP will be subject to the danger of direct
lightning.
• DANGER!
DO NOT perform an installation and wiring of the MATP
during thunder storms.
• Indoor use.
• Be sure to house the MATP inside an metal enclosure for
safety. Even though the MATP is capable of withstanding
an induced discharge current expected in normal condi-
tions, it is entirely possible to be hit by a certain strong
lightning exceeding its designed capacity. It is also sub-
ject to a direct hit by a lightning. The MATP will be de-
stroyed by such high lightning energy.
• We recommend to install the MATP in a position where
the monitor LED is clearly visible to facilitate inspection
and maintenance.
• DO NOT install the MATP where it is subjected to con-
tinuous vibration. Do not apply physical impact to the
MATP.
• Environmental temperature must be within -25 to +80°C
(-13 to +176°F) and relative humidity within 30 to 90%
RH in order to ensure adequate life span and operation.
■
HIGH TEMPERATURE
• DANGER!
The front parts of the surface may be hot. DO NOT grab
the sides of the module. When the MATP’s discharge
element (zinc oxide element) gradually degrades, its in-
creased leakage current causes high temperature at the
surface of the MATP, until the discharge element is final-
ly separated from the power line by the thermal breaker.
However, a part of the module may already be too hot to
touch safely if the module is near the end of its life.
■
DIELECTRIC STRENGTH TESTING
• Conduct the dielectric strength test with all power sup-
ply wires removed. The MATP will start discharging at
the described discharge voltage if a test voltage is applied
with all power supply wires connected. It will result in an
insulation failure.
■
AND....
• We recommend that you keep spare MATPs so that you
can replace them quickly when necessary.
