ADDITIONAL NOTES

Caution! Failure to use all four screws to attach the EF2241 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 EF2241 in a rack, consideration should be given to airflow and operating ambient temperatures inside the rack. To ensure safe operation of the EF2241, ambient operating temperatures inside the rack should not exceed 40 degrees Celsius. Allow 2 inches (51mm) of open space in front of the EF2241, 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 EF2241.

Caution! Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits could have an overcurrent pro- tection and supply 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).
