Caution! Failure to use all four screws to attach the EF2280 to the rack
may result in uneven loading and cause a safety hazard.
Caution! Ensure that the power supply is securely located such that it
cannot become dislodged and fall. Such a fall could cause
personal injury or equipment failure.
Caution! When mounting a EF2280 in a rack, consideration should be
given to airflow and operating ambient temperatures inside
the rack. To ensure safe operation of the EF2280, ambient
operating temperatures inside the rack should not exceed 40
degrees Celsius. Allow 2 inches (51mm) of open space in
front of the EF2280, 2 inches (51mm) on either side, and 4
inches (102 mm) behind the unit for proper ventilation.
Equipment should not be installed in the rack in such a way
as to interfere with the ventilation of the EF2280.
Caution! Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overload-
ing of circuits could have an overcurrent protection and sup-
ply wiring. Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.
Caution! Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply
connections other than direct connection to the Branch (use
of power strips).
