2.8 Notes and Cautions
2.8.1 Installation Notes
When the product needs to be installed on the rack, 8 screws at least M6*16 should
be used to fix it. The rack for installation shall bear at least four times the total weight
of the mounted equipment.
a) 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.
b) 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.
c) Mechanical Loading - Mounting of the equipment in the rack should be such that
a hazardous condition is not achieved due to uneven mechanical loading.

d) 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 overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when addressing
this concern.
e) 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).
