specifications are subject to change without prior notice or obligation. All statements,
information, and recommendations in this document do not constitute a warranty of any
kind, express or implied.
Any performance data contained herein was determined in a controlled environment.
Therefore, the results obtained in other operating environments may vary significantly.
Some measurements may have been made on development-level systems and there is no
guarantee that these measurements will be the same on generally available systems.
Furthermore, some measurements may have been estimated through extrapolation. Actual
results may vary. Users of this document should verify the applicable data for their specific
environment.
This information contains examples of data and reports used in daily business operations.
To illustrate them as completely as possible, the examples include the names of individuals,

UL Statement
Rack Mount Instructions - The following or similar rack-mount instructions are included with
the installation instructions:
1. Elevated Operating Ambient - If installed in a closed 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.
2. Reduced Air Flow - Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
3. Mechanical Loading - Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit Overloading –Careful 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 overcurrent protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
5. Reliable Earthing - Reliable earthing of rack-mounted 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).

CAUTION:
The main purpose of the system left and right ears are for 19” rack use
only. Do NOT use those ears to carry or transport the system.
The ITE is not intended to be installed and used in a home, school or public area accessible
to the general population, and the thumbscrews should be tightened with a tool after both
initial installation and subsequent access to the panel.
Warning: Always remove all power supply cords before service
This equipment intended for installation in restricted access locations.
Access should only be allowed by qualified SERVICE PERSONS or by USERS who have
been instructed about the reasons for the restrictions applied to the location and about
any precautions that shall be taken.
Access is through the use of a TOOL or lock and key, or other means of security, and is
controlled by the authority responsible for the location.
Recommended operation temperature: 0 ~ 40 (31.99 ~ 103.99 F); operation rating
(100-127 Vac, 50-60Hz, 10.0A; 200-240 Vac, 50-60Hz, 5.0A)
CAUTION: (English)
Risk of explosion if battery is replaced by incorrect type. Please replace
the same or equivalent type battery use and dispose of used batteries
according to the instructions.
ATTENTION: (French)
IL Y A RISQUE D'EXPLOSION SI LA BATTERIE EST REMPLACEE PAR UNE
