–
Connect outdoor equipment to the unit's inputs only after this unit has had its grounding
plug connected to a grounded outlet or its ground terminal is properly connected to a
ground source.
–
Disconnect the unit's input connectors from outdoor equipment before disconnecting the
grounding plug or grounding terminal.
–
Follow proper safety precautions such as grounding for any outdoor device connected to
this unit.
U.S.A. models only - Section 810 of the National Electrical Code, ANSI/NFPA No.70, provides
information regarding proper grounding of the mount and supporting structure, grounding of
the coax to a discharge unit, size of grounding conductors, location of discharge unit,
connection to grounding electrodes, and requirements for the grounding electrode.
Grounding and polarization - This unit may be equipped with a polarized alternating current
line plug (a plug with one blade wider than the other blade). This safety feature allows the
plug to fit into the power outlet in only one way. If unable to insert the plug fully into the
outlet, contact a locally certified electrician to replace the obsolete outlet. Do not defeat the
safety purpose of the polarized plug.
Alternately, this unit may be equipped with a 3-pole grounding plug (a plug with a third pin for
earth grounding). This safety feature allows the plug to fit into a grounded power outlet only.
If unable to insert the plug into the outlet, contact a locally certified electrician to replace the
obsolete outlet. Do not defeat the safety purpose of the grounding plug.
Moving - Disconnect the power before moving the unit. Move the unit with care. Excessive
force or shock may damage the unit and the hard disk drives.
Outdoor signals - The installation for outdoor signals, especially regarding clearance from
power and lightning conductors and transient protection, must be in accordance with NEC725
and NEC800 (CEC Rule 16-224 and CEC Section 60).
Permanently connected equipment - Incorporate a readily accessible disconnect device
external to the equipment.
Pluggable equipment - Install the socket outlet near the equipment so it is easily accessible.
Rack-mount
–
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.
–
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).
