6. Assembly, location, and mounting requirements

Series 2400 instruments use a heat sink to dissipate heat, and the Mode ls 2410, 2420 , 2430, and 244 0 also have a cooling
fan. The left side of the case is cut out to expose the black, finned heat sink, which gets hot enough to cause burns. You
should assume that the heat sink is still hot even when the instrument is turned off (it takes a long time to cool off).

2 PA-1018 Rev. D / March 2013

Series 2400 Customer Documentation Safety Supplement

WARNING NEVER touch the heat sink located on the left side of the Series 2400 instrument’s

case. This heat sink could be hot enough to cause burns.

CAUTION Excessive heat will degrade the Series 2400 instrument’s performance, and could damage

the unit. The Series 2400 must be operated in an environment where the ambient
temperature does not exceed 50° C (122° F).

To prevent damaging heat build-up and ensure specified performance:

• Keep the heat sink free of dust, dirt, and contaminates, which will diminish its ability to dissipate heat.

• Do not block the bottom cooling vents. NEVER remove the plastic feet and place the Series 2400 directly on a flat
surface. NEVER operate the Series 2400 when it is sitting on a surface that conforms to the shape of the unit (such
as carpet). This could block the bottom cooling vents.

• Do not position any devices adjacent to the Series 2400 that force air (heated or unheated) into or onto its cooling
vents or surfaces. This additional airflow could diminish accuracy performance.

• When rack mounting the Series 2400, ensure there is adequate airflow around the bottom and sides for proper
cooling. Adequate airflow keeps air temperatures within approximately one inch of the Ser ies 2400 surface s within
specified limits under all operating conditions.

• Do not rack mount high power-dissipation equipment adjacent to the Series 2400, because excessive heating could
occur. The specified ambient temperature must be maintained around the surfaces of the Series 2400 to maintain
specified accuracies.

• In convection-cooled rack-mounted systems, place the hottest equipment (for example, a power supply) at the top
of the rack to ensure proper cooling. Place precision equipment, such as the Series 2400, in the lowest possible
position in the rack, where temperatures are coolest. Adding spacer panels below the Series 2400 will ensure
adequate air flow.

7. Supply connection and grounding requirements

Always use the mains supply cord provided with the instrument, or use a cord with the same (or better) ratings than the one
provided. Never use an inadequately rated cord.

Before operating an instrument, ensure that the line cord is connected to a properly grounded, appropriately rated power
receptacle. Inspect the connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before ea ch use.

When installing equipment where access to the main power cord is restricted (such as rack mounting), a separate main
input power disconnect device must be provided in close proximity to the equipment and within easy reach of the operator.

8. Ventilation requirements

Proper ventilation must be maintained to prevent overheating. Th e Models 2410, 2420, 24 25, 2430, and 2440 us e a cooling
fan to keep them from overheating; the Models 2400 and 2401 do not have a cooling fan. Refer to the WARNING and
CAUTION statements in paragraph 6. Assembly, location, and mounting requirements for details about maintaining proper
ventilation of all Series 2400 instruments.

9. Environmental conditions

To maintain safety, the following environmental conditions must be maintained:

• For indoor use only

• Altitude up to 2000 m (6,562 ft)

• Temperature 0° C to 40° C (32° F to 104° F)

• Maximum relative humidity: 80 percent for temperatures up to 31° C (88° F), decreasing linearly to 50 percent relative
humidity at 40° C (104° F)

• Mains supply voltage fluctuations not to exceed ±10 percent of the nominal voltage

• Maximum mains transient overvoltage category II
