Warning: Class I Equipment. This equipment must be earthed.
The power plug must be connected to a properly wired earth
ground socket outlet. An improperly wired socket outlet could
place hazardous voltages on accessible metal parts.
6
Pluggable Equipment. The socket outlet shall be installed near
the equipment and shall be easily accessible.

Caution: Air vents must not be blocked and must have free
access to the room ambient air for cooling. 8
Warning: Operating Temperature. This product is designed for a
maximum ambient temperature of 40° degrees C. 9
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.
23
Warning: Mounting of the equipment in the rack should be such
that a hazardous condition is not created due to uneven
mechanical loading.
27
If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater
than the room ambient temperature. Therefore, consideration
should be given to installing the equipment in an environment
compatible with the manufacturer’s maximum rated ambient
temperature (Tmra).
38
Caution: 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.
39
Warning: Reliable earthing of rack-mounted equipment should
be maintained. Particular attention should be given to supply
connections other than direct connections to the branch circuits
(e.g., use of power strips).
