Bench Operation

A fan cools the electronic load by drawing air through the top and sides and exhausting it out the back. Minimum clearances for bench operation are 1 inch (25 mm) along the sides.

Do not block the fan exhaust at the rear of the unit.

Rack Mounting

The N3300A electronic load can be mounted in a standard 19-inch rack panel or cabinet. Rack mount kits are available as Option 908 and 909 (with handles). Support rails are also required for rack mounting. These are normally supplied with the cabinet and are not included with the rack mount options.

The N3301A electronic load can also be mounted in a standard 19-inch rack panel or enclosure using an Option 908 rack mount kit (see Figure 3-4). A rack mount kit for joining two half-rack units is available as Option 800. Option 800 must also be used if you are mounting other instruments next to a N3301A electronic load. Support rails are also required for rack mounting. These are normally supplied with the cabinet and are not included with the rack mounting options.

If you are installing equipment on top of your electronic load in the cabinet, use a filler panel above the unit to ensure adequate space for air circulation. A 1U panel (EIA Standard RS-310-C) as shown in Figure 3-4 is sufficient. If your cabinet has a circulation fan, avoid installing the Electronic Load too close to the cabinet fan. The cabinet fan may restrict the airflow required through the Electronic Load.
