To remove system power before performing maintenance or replacement of components:
Follow precautions for removing hazardous voltage from the probe or other types of test fixtures

2.
Shut down the system computer using the instructions in either
(on page 3-5) or
(on page 3-5) in this guide.

4.
Place the main circuit breaker on the power distribution unit (PDU) (on the back of the cabinet) in
the OFF position.
5.
Disconnect the source power to the S530 system (power cord on back of PDU).
6.
Place the lock and tag on the main circuit breaker of the PDU.
7.
Wait five minutes before accessing any high-voltage units.
General replacement procedure
Severe personal injury or death due to electric shock or electrocution may result if power is
not removed before working inside the cabinet. Always disconnect the cabinet line cords
from the AC line power receptacles before opening the system cabinet. Also, never turn on
the system until all connections and safety grounds are installed.
1.
Remove power and place the lock and tag on the main circuit breaker of the power distribution
unit (PDU) (see
(on page 2-19)).
2.
Disconnect and tag cabling to the unit requiring removal. Do not change cable routing or
securement.
3.
Properly supporting the unit, remove it from the system cabinet.
Adjustment
Keithley Instruments recommends annual adjustment of the individual instruments in your system and
offers this as an on-site service. A field service engineer (FSE) will adjust instrumentation and perform
system verification according to the warranted system specifications. For more information about
adjustment or other S530 services, contact your local Keithley office.
You can also do system verification as described in the S530 Parametric Test System Diagnostics
and Verification Manual.
