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).
