■ 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.

MODEL

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.
