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).
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 another place.
The machine can only be used in a fixed location such as labs or computer facilities.
Mounting Installation Precaution
Environment:
Do not install and/or operate this unit in any place that flammable objects are stored or used in.
Elevated Operating Ambient - If installed in a small confined space or multi-unit rack assembly, the
operating ambient temperature of the 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 the rack or on the wall 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 or on the wall should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
Circuit Overloading - Consideration should be given to 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 the 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).
Installation & Operation:
The installation of this product must be performed by trained specialists; otherwise, a non-specialist
might create the risk of the unit's falling to the ground or other damages.
Lanner Electronics Inc. shall not be held liable y for any losses resulting from insufficient strength for
supporting the unit or use of inappropriate installation components.
