Hoisting Heavy Objects
Warning
When hoisting heavy objects, ensure that nobody is standing or walking under the hoisted
object.
l
Ensure the hoister can meet hoisting requirements when disassembling heavy
equipment, or moving and replacing equipment.
l The installation personnel must be duly trained and qualified for hoisting operations.
l
Hoisting tools must be inspected and complete before service.
l
Make sure that hoisting tools are fixed firmly on a sufficiently secured object or wall
before the hoisting operation.
l
Give brief oral instructions during hoisting operations to prevent any mishap.
Unplugging/Plugging a Module
l
Never plug a module with excessive force, to ensure that the pins on the backplane
do not get deformed.
l Plug the module right into the slot and make sure module circuit faces do not contact
each other lest any short circuit may occur.
l
Keep hands off the module circuit, components, connectors and cable trough when
holding a module.
Rack Mount Safety Instructions
Rack Mount Instructions - The following or similar rack-mount instructions are included
with the installation instructions:
l
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.
l
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.
l
Mechanical Loading - Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
l
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.
equipment nameplate ratings should be used when addressing this concern.
l 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).
