Precautions
To avoid any device impairment or bodily injury because of improper
use, follow the precautions listed below:
• Do not place the RPS unit on an unstable case or tabletop, and
ensure that the rack and the workbench are firm enough to support
the RPS unit and its accessories.
• Make sure that the ventilation and heat dissipation systems of the
rack and the table-top are good. Make sure that enough room is
left around the air intake and outlet of the RPS unit to allow good
heat dissipation.
• This RPS unit is designed for indoor use only. Make sure that the
temperature in the equipment room is within the range of 0°C to
45°C (32°F to 113°F), and the humidity within the range of 10% to
90%.
• Keep the RPS unit away from any heavy-duty radio transmitter,
radar transmitter, and high-frequency devices working in high
current. Take electromagnetic shielding measures if necessary.
• Use a single-phase three-wire power socket with a neutral point
connector or a multi-functional power socket for computers. Make
sure that the neutral point of the power source is well grounded.
• Make sure that the power source satisfies the voltage requirement
of the RPS unit.
• Interface cables must be routed indoors. Otherwise, over-voltage
and over-current may damage the device. As for power cables
