loading. E25

recommends that you get assistance when mounting the chassis in
an equipment rack. E28
Warning
This unit might have more than one power cord. To reduce the risk
of electric shock, disconnect all power cords before servicing the

Note
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).
E35
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. E36

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).
