1. Ensure that the "Meeting Electrical and Environmental Requirements" on page 3 are

met.

2. Verify that the power cable is not damaged, and that the power source outlet provides a

protective earth ground contact. Note that the Figure 2 depicts only one type of power

source outlet. Refer to Figure 3 on page 6 to see the different types of power cord plugs

that can be used with your test set. Cables are available in different lengths. For

descriptions and part numbers of cables other than those described in Figure 3, Refer to

"Contacting Agilent" on page 74.

3. If this product is to be powered by autotransformer, make sure the common terminal is

connected to the neutral (grounded) side of the ac power supply.

WARNING This is a Safety Class I product (provided with a protective earthing

ground incorporated in the power cord). The mains plug shall only

be inserted into a socket outlet provided with a protective earth

contact. Any interruption of the protective conductor, inside or

outside the instrument, is likely to make the instrument dangerous.

Intentional interruption of the protective conductor is prohibited.

cabinet. If the total power dissipated in the cabinet is greater than 800 watts,

forced convection must be used.
