CHAPTER 2. INSTALLATION
Preparing for the Installation
The following information is prepared for safe installation of the unit.
This unit can be placed on a flat table or installed in the rack. It should not be
used vertically or skew, but horizontally. The location of the unit and the
composition of wiring are very important in properly operating the system. When
equipment is placed too close or if ventilation is not properly done, system may
not work properly, and maintenance of the system may be difficult. In order to
prevent system failure and to reduce system shut-down by outside
environmental factors, air circulation in the system operating room, and the
cover of the unit must be fixed. Do not open the cover voluntarily because high
voltage within the unit may cause electric shock.
PHYSICAL & ENVIRONMENTAL
¥ Operating Temperature : 0 °C to 40 °C
¥ Maintenance Temperature : -20 °C to 60 °C
¥ Operating Humidity : 20% to 85% (RH)
¥ Maintenance Humidity : 20% to 95% (RH)
¥ Power Supply : 100 ~ 240 VAC
¥ Power Consumption : less than 13W
¥ Frequency : 50/60 Hz
CAUTIONS
When system is operated, input voltage range must be within 10% of nominal
voltage, and power consent should be grounded. Heating devices such as hair
dryer, iron, refrigerator should not be used together. For safe power supply, AVR
(Automatic Voltage Regulator) is recommended.
The connector linked to this equipment can affect EMI,so it is recommended to
coil the CORE-FERRITE for use.

Precautions when Installing
Precautions when Installing
¥ Be sure to turn the unit off before installing.
¥ Avoid shock or vibration since
they may cause unit malfunction.
¥ Keep away from magnets, radio or TV to
avoid magnetic damage.
¥ During or after installing the unit, be sure to
maintain the area around the unit clean.
2-2
Digital Multiplexer SDM-090(P)
15Cm
¥ Place the unit on a flat surface and
maintain temperature properly. Allow 15
cm of clearance between the rear panel
and the wall.
¥ Be careful not to drop any conductive
materials into the hole for ventilation
¥ When replacing built-in fuse, be sure
to turn the power off, and unplug
the unit.
¥ Avoid locating the unit where direct sunlight
will fall, and maintain it cool. Keep tools
and equipment away from people so that
they would not be hurt.
¥ Power Outlet should be grounded
2P(or 3P)Type.
2-3
Digital Multiplexer SDM-090(P)
¥ If ignoring smoke or smell while using the unit, fire
or electric shock may occur. In this case, turn the
power switch off immediately, and consult
professionals in the closest service center.
¥ Be sure to check dangers, which may occur due to
damped floor, ungrounded power extension
cable, worn power cord or lack of safety
grounding.
CAUTIONS
When cleaning this unit, be sure to wipe with a dried cloth. If the unit is heavily
contaminated, wipe it with a soft cloth dampened with a mild detergent solution,
then wipe dry with a soft clean cloth. Do not use chemicals such as alcohol,
benzene, or thinner because a chemical reaction could result permanent
damaging of the cabinet surface.
