Lockout and tagout
For maximum safety while power is applied, always perform a lockout and tagout procedure. Remove
power from the entire test system and discharge capacitors before connecting or disconnecting
cables or any instrument, including the device under test. When you perform lockout and tagout
procedures, make sure that you note all warning labels on the cabinet and instruments (see the
following figure).
Figure 26: Hazardous warning label
Severe personal injury or death due to electric shock or electrocution may result if power is
not removed before working inside the cabinet. Always perform the lockout and tagout
procedure before opening the system cabinet. Also, never turn on the system until all
connections and safety grounds are installed.
To remove system power:
1.
You must shut down the software and remove all power from the computer and the system (see
(on page 3-4) or
(on page 3-5)).
Before proceeding, you must make sure the power indicator on the front door is not
illuminated. See the following figure for an example of what the indicator looks like when
illuminated.

2.
Place the breaker for the power distribution unit (PDU) in the OFF position. The location of the
PDU is at the back of the cabinet below the rear door.
3.
If you are working in the system cabinet, disconnect the system cabinet line cord from the AC line
power receptacles.
