Power Supply and Blown Fuses
Before turning on the E5070B/E5071B power, check the following.
Verification of the Power Supply
Confirm that the power supplied to the E5070B/E5071B meets the following requirements:
Verification and Connection of Power Cable
The three-wire power cable attached to the E5070B/E5071B has one wire serving as a
ground. Using this power cable allows the E5070B/E5071B to be grounded, thereby
protecting you against electrical shock from the power outlet.
Step 1.
Confirm that the power cable is not damaged.
WARNING
NEVER use a power cable showing any sign of damage. Faulty cables can cause
electrical shock.
Step 2.
Use the supplied cable to connect between the power cable receptacle (Figure 2-11 on
page 35) on the rear panel of the E5070B/E5071B and a three-wire power outlet with the
grounding prong firmly connected in the ground slot.
WARNING
Use the supplied power cable with grounding wire to securely ground the
E5070B/E5071B.
Figure 2-10 shows the power cable options.
