Safety Precautions
■
Installing the main power supply by a qualified electrician, according to power authority
regulations. Make sure all powering are wired with an earth leakage, according to local
regulations.
■
It is recommended to install the encoder within 1.5m (approximately 5 feet) from an easily
accessible grounded AC outlet.
■
When the encoder is rack-mounted, ensure that the rack is correctly grounded.
DANGER:
To ensure that the rack is correctly grounded by a qualified electrician. Incorrectly grounded
equipment may result in electrical shock.
DC Power Supply to the Unit
In the case the unit is fitted with DC power inputs, the following are required:
■
Never work on DC powered equipment while power is applied. Disconnect power before
making connections to the device.
■
Ensure a suitable overcurrent device is inline between the equipment and the power source.
Rack Mount 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
temperature. Consideration should be given to installing the equipment in an environment
compatible with the maximum ambient temperature (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 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.
■
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).
Handling Fibre Channel Cables
■
Always read and comply with the handling instructions on the shipping container.
■
Follow all ESD precautions and approved fiber cleaning procedures.
■
The fiber is made of a very pure, expensive glass and should be treated with great care.
Handle fibers only in areas that are very clean and do not contain sharp objects.
■
Wear finger cots or gloves as dirt and oils can damage the fiber and contaminate connectors.
■
Do not allow kinks or knots to develop in the fiber. If tangles occur, carefully work out the
tangles avoiding pulling or bending the fibre beyond its bend radius.
■
Always use the correct tools for stripping and cleaving the fiber. It will save time and reduce
breakage caused by scratches.
