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 ~ 35℃(31.99 ~ 95°F); operation rating (100-127
Vac, 50-60Hz, 10.0A; 200-240 Vac, 50-60Hz, 5.0A)
