CAUTION
Before plugging a cable into any port, be sure to discharge the voltage stored on the cable by touching the electrical contacts to
ground surface.
DANGER
If the installation requires a different power cord than the one supplied with the device, make sure you use a power cord
displaying the mark of the safety agency that defines the regulations for power cords in your country. The mark is your
assurance that the power cord can be used safely with the device.
Preparing the installation site
EPS4000 external power supplies can be mounted in a standard 19-inch equipment rack or on a flat surface.
The installation site should meet these requirements:
∙
Be at the center of all the devices you want to link, and near a power outlet.
∙
Maintain temperatures within 0 to 50°C (32 to 122°F) and humidity levels within 5 to 95%, non-condensing.
∙
Provide adequate space (approximately 5.08 cm [2 in.]) on all sides for proper airflow.
∙
Be accessible for installing, cabling, and maintaining the devices.
∙
Allow the status LEDs to be clearly visible.
∙
Allow for twisted-pair cables to be routed away from power lines, fluorescent lighting fixtures, and other sources of electrical
interference, such as radios and transmitters.
∙
Provide a separate grounded power outlet that provides 100 to 240 VAC, 50 - 60 Hz, is within 2.44 m (8 ft) of each device,
and is powered from an independent circuit breaker.
∙
As with any electrical equipment, a filter or surge suppressor is recommended.
Rack-mount installation considerations
Before mounting the external power supply in a rack, consider the following factors:
∙
Temperature: Because the temperature within a rack assembly may be higher than the ambient room temperature, check that
the rack-environment temperature is within the specified operating temperature range.
∙
Airflow: Be sure that the airflow direction for all equipment in a rack is the same or consistent.
∙
Mechanical loading: Do not place any equipment on top of a rack-mounted device.
∙
Circuit overloading: Be sure that the supply circuit to the rack assembly is not overloaded.
∙
Grounding: Rack-mounted equipment should be properly grounded.
Installing the device
You can install the device on a desktop or in an equipment rack.
DANGER
Mount the devices you install in a rack as low as possible. Place the heaviest device at the bottom and progressively place
lighter devices above.
