Mounting
RPU units can be mounted in a standard 19-inch e quipment rack or on a
desktop or shelf. Mounting instructions for each type of site follow.

Rack Mounting

Before rack mounting the unit, pay par ticular attention to the following
factors:
• Temperature: Since the temperature within a rack assembly may be
higher than the ambient room temperature, check that the
rack-environment temperature is within the specified operating
temperature range.
• Mechanical Loading: Do not place any equipment on top of a
rack-mounted unit.
• Circuit Overloading: Be sure that the supply circuit to the rack
assembly is not overloaded.
• Grounding: Rack-mounted equipment should be properly grounded.
Particular attention should be given to su pply connections other than
direct connections to the mains.
