• Reverse air flow — To ensure cool air intake and to avoid hot air blow out from the I/O panel, ensure
you have the necessary clearance.
• Reliable earthing — Maintain reliable earthing of rack-mounted equipment. Pay particular attention to
the supply connections other than the direct connections to the branch circuit; for example, the use
of the power strips.
• Do not mount the equipment with the Utility panel facing in the downward position.
NOTE: These instructions are a condensed reference. Read the safety instructions in your Safety,
