Cleaning

To prevent electric shock, unplug the unit before cleaning.

Use a dry cloth or one slightly dampened with water to clean the external case parts. Do not attempt to clean internally.

Location and Temperature

Bench Operation

The “Supplemental Characteristics” in Chapter 1 give the dimensions of your power supply. The cabinet has plastic feet that are shaped to ensure self-alignment when stacked with other Agilent System II cabinets. The feet may be removed for rack mounting. Your power supply must be installed in a location that allows sufficient space at the sides and rear of the cabinet for adequate air circulation. Minimum clearances are 1 inch (25 mm) along the sides. Do not block the fan exhaust at the rear of the supply.

Rack Mounting

Series 668xA and 669xA supplies weigh 51.3 kg (113 lb). Obtain adequate help when mounting the supply in the rack.

The power supply can be mounted in a standard l9-inch rack panel or cabinet. Rack mounting kits are available as Option 908 or 909 (with handles). Installation instructions are included with each rack mounting kit.

Series 667xA, 668xA, &669xA

Series 667xA, 668xA, 669xA supplies require instrument support rails for non-stationary installations. These are normally ordered with the cabinet and are not included with the rack mounting kits.

Temperature Performance

A variable-speed fan cools the supply by drawing air through the sides and exhausting it out the back. Using Agilent rack mount or slides will not impede the flow of air. The temperature performance is as follows:

Series 664xA & 665xA Operates without loss of performance within the temperature range of 0 °C to 40 °C and with derated output from 40 °C to 55 °C.

Series 667xA, 668xA, &669xA Operates without loss of performance within the temperature range of 0 °C to 55 °C.

It a Series 664xA or 665xA power supply is operated at full output current for several hours, the sheet metal immediately under the transformer (near the right front) can get very hot. Do not touch this area of the cabinet. The line cord also can become quite warm. Both of these conditions are normal.
