Placement And Rack Mounting; Cooling Considerations; Connecting The 5725A Amplifier - Fluke 5500A Operator's Manual

2-7. Placement and Rack Mounting

You may place the calibrator on a bench top or mount it in a standard-width, 24-inch
(61-cm) deep equipment rack. For bench-top use, the calibrator is equipped with non-
slipping, non-marring feet. To mount the calibrator in an equipment rack, use the 5500A
Rack Mount Kit, Model Y5537. Instructions for rack mounting the calibrator are packed
with the rack mount kit.

2-8. Cooling Considerations

To avoid risk of injury, never operate or power the 5500A
Calibrator without the fan filter in place.
Damage caused by overheating may occur if the area around
the air intake is restricted, the intake air is too warm, or the air
filter becomes clogged.
Baffles direct cooling air from the fan throughout the chassis to internally dissipate heat
during operation. The accuracy and dependability of all internal parts of the calibrator
are enhanced by maintaining the coolest possible internal temperature. You can lengthen
the life of the calibrator and enhance its performance by observing the following rules:
The area around the air filter must be at least 3 inches from nearby walls or rack
enclosures.
The exhaust perforations on the sides of the calibrator must be clear of obstructions.
The air entering the instrument must be at room temperature: make sure the exhaust
air from another instrument is not directed into the fan inlet.
Clean the air filter every 30 days or more frequently if the calibrator is operated in a
dusty environment. (See Chapter 7, "Maintenance" for instructions on cleaning the
air filter.)

2-9. Connecting the 5725A Amplifier

The 5500A provides an interface connection for the Fluke 5725A Amplifier. You
designate whether the 5500A or 5725A is the preferred source of current and voltage in a
calibrator setup menu (see Chapter 4, "Front Panel Operation"). A single connection
cable provides the complete link for analog and digital control signals. Refer to the
5725A Instruction Manual for installation instructions.
