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
¥ 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.
