� Make sure that hoisting tools are fixed firmly on a sufficiently
secured object or wall before the hoisting operation.
� Give brief oral instructions during hoisting operations to pre-
vent any mishap.
� Never plug a module with excessive force, to ensure that the
pins on the backplane do not get deformed.
� Plug the module right into the slot and make sure module cir-
cuit faces do not contact each other lest any short circuit may
occur.
� Keep hands off the module circuit, components, connectors
and cable trough when holding a module.
Rack Mount Instructions - The following or similar rack-mount in-
structions are included with the installation instructions:
� 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. There-
fore, consideration should be given to installing the equipment
in an environment compatible with the maximum ambient tem-
perature (Tma) specified by the manufacturer.
� 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.
� Mechanical Loading - Mounting of the equipment in the rack
should be such that a hazardous condition is not achieved due
to uneven mechanical loading.
� Circuit Overloading - Consideration should be given to the con-
nection of the equipment to the supply circuit and the effect
that overloading of the circuits might have on overcurrent pro-
tection and supply wiring. Appropriate consideration of equip-
ment nameplate ratings should be used when addressing this
concern.
� Reliable Earthing - Reliable earthing of rack-mounted equip-
ment should be maintained.
given to supply connections other than direct connections to
the branch circuit (e.g. use of power strips).
Note:
Do not perform maintenance or debugging independently, unless
a qualified person is present.
�
Perform an airtight test before RRU delivery, and prohibit dis-
assembling the RRU on site.
� Replacing any parts or making any changes to the equipment
might result in an unexpected danger. Therefore, be sure not
to replace any parts or perform any changes to the equipment
unless authorized otherwise.
�
Due to that RRU is in high temperature during running, the RRU
should be installed in some regions out of operators' reach or
strictly restricted.
Particular attention should be
