•
To prevent electric shock, do not remove the cover of this product. There are no user-
serviceable parts inside. This unit contains hazardous voltages and should only be opened
by a trained and qualified technician.
•
Do not work on equipment or cables during periods of lightning activity.
•
Check to see if there are any exposed copper strands coming from the installed wire. When
this installation is done correctly there should be no exposed copper wire strands
extending from the terminal block. Any exposed wiring can conduct harmful levels of
electricity to persons touching the wires.
•
The power source for the device should be located near the unit and should be easily
accessible.
•
Circuit Overloading: Consideration should be given to the connection of the equipment to
the supply circuit and the effect that overloading of circuits might have on overcurrent
protection and supply wiring. Appropriate consideration of equipment nameplate ratings
should be used when addressing this concern.
Rack-mount safety precautions
For your protection, observe the following rack-mount safety precautions when setting up your
equipment:
•
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 (for example, use of power strips).
•
For safety, equipment should always be loaded from the bottom up. That is, install the
equipment that will be mounted in the lowest part of the rack first, then the next higher
systems, etc.
•
To prevent the rack from tipping during equipment installation, the anti-tilt bar on the rack
must be deployed.
•
The mounting brackets provided must be used to securely mount the device in a rack-
mount unit.
