Lanner FW-8894 - Manual (Page 4)

EMC Notice
This equipment has been tested and found to comply
with the limits for a Class A digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful
interference when the equipment is operated in a
commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction
manual, may cause harmful interference to radio
communications. Operation of this equipment in a
residential area is likely to cause harmful interference
in which case users will be required to correct the
interference at their own expense.
Safety Guidelines
Follow these guidelines to ensure general safety:
Keep the chassis area clear and dust-free during and •
after installation.
Do not wear loose clothing or jewelry that could get
•
caught in the chassis. Fasten your tie or scarf and roll
up your sleeves.
Wear safety glasses if you are working under any
•
conditions that might be hazardous to your eyes.
Do not perform any action that creates a potential
•
hazard to people or makes the equipment unsafe.
Disconnect all power by turning off the power and
•
unplugging the power cord before installing or
removing a chassis or working near power supplies
Do not work alone if potentially hazardous
•
conditions exist.
Never assume that power is disconnected from a
•
circuit; always check the circuit.
LITHIUM BATTERY CAUTION:
Risk of Explosion if Battery is replaced by an incorrect
type. Dispose of used batteries according to the
instructions.
Installation only by a trained electrician or only by •
an electrically trained person who knows all English
Installation and Device Specifications which are to
be applied.
Do not carry the handle of power supplies when
•
moving to other place.
The machine can only be used in a fixed location
•
such as labs or computer facilities.
Operating Safety
Electrical equipment generates heat. Ambient air •
temperature may not be adequate to cool equipment to
acceptable operating temperatures without adequate
circulation. Be sure that the room in which you choose to
operate your system has adequate air circulation.
Ensure that the chassis cover is secure. The chassis design
•
allows cooling air to circulate effectively. An open chassis
permits air leaks, which may interrupt and redirect the flow
of cooling air from internal components.
Electrostatic discharge (ESD) can damage equipment and
impair electrical circuitry. ESD damage occurs when electronic
components are improperly handled and can result in complete
or intermittent failures. Be sure to follow ESD-prevention
procedures when removing and replacing components to avoid
these problems.
Wear an ESD-preventive wrist strap, ensuring that it makes •
good skin contact. If no wrist strap is available, ground
yourself by touching the metal part of the chassis.
Periodically check the resistance value of the antistatic
•
strap, which should be between 1 and 10 megohms
(Mohms).
Rack Mounting Installation Environment Precaution
Elevated Operating Ambient - If installed in a closed 1.
or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than
room ambient. Therefore, consideration should be given
to installing the equipment in an environment compatible
with the maximum ambient temperature (Tma) specified
by the manufacturer.
Reduced Air Flow - Installation of the equipment in a rack
2.
should be such that the amount of air flow required for
safe operation of the equipment is not compromised.
Mechanical Loading - Mounting of the equipment in the
rack should be such that a hazardous condition is not
created due to uneven mechanical loading.
Mechanical Loading - Mounting of the equipment in the
3.
rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
Circuit Overloading - Consideration should be given to
4.
the connection of the equipment to the supply circuit and
the effect that overloading of the circuits might have on
over-current protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be
used when addressing this concern.
Reliable Earthing - Reliable earthing of rack-mounted
5.
equipment should be maintained. Particular attention
should be given to supply connections other than direct
connections to the branch circuit (e.g. use of power strips).”
