When performing the removal and installation procedures in this section or any maintenance on the system,
lockout and tagout line power as follows:
1. Press the Emergency Off (EMO) button on the system cabinet door. The location of the EMO is either on
the front door or on a panel near the top of rack if the cabinet without the door is used.
NOTE
Details on the “Emergency Off (EMO) button” are in Section II.
2. Place the power switch for the PDU (Power Distribution Unit) in the OFF position. The location of the PDU
is in the bottom of the cabinet facing forward. If two PDUs are present in the system, make sure to turn
both power switches to the OFF position. The second PDU is in the bottom of the cabinet facing to the
rear.
3. If working in the system cabinet, disconnect the system cabinet line cord(s) from the AC line power
receptacles.
NOTE
Larger S500 systems may have two Model 42000-PDU line cords. When removing
power, make sure to disconnect all system cabinet line cords from AC line power
receptacles.
4. Verify that all power has been removed and discharged from the system cabinet. This can be done by
switching the main power switch to the ON position. Verify that the green light does not illuminate. If light
does not come on, the power is off. Turn main power switch back to the OFF position.
5. Lockout and tagout the system source power connection in accordance with your company’s lockout/tagout
policy. Attach a standard clamshell type of lockout device with a key lock on the male end of the
disconnected line cords.
Installation and connections
WARNING The
following
installation and connection procedures are to be performed by
trained site installers who are familiar with the associated physical and
electrical hazards.
NOTE
Larger S500 systems may have two Model 42000-PDU line cords. Plug each PDU

Position the system cabinet
The system cabinet contains the controller and instrumentation for the test system. The cabinet is on casters
allowing it to be rolled on a hard surface floor. The two steering casters in back swivel, while the two casters at the
front are in fixed positions.
1. Carefully roll the system cabinet to its desired location next to the prober. Allow approximately 14 inches
(nominal) of clearance between the cabinet and other instrumentation
2. Lock the casters by pushing down on the caster locking mechanisms located near the front-bottom of the
cabinet.
3. Using the supplied wrench, adjust the height of the four legs such that the weight of the cabinet is on the
legs and not on the casters. Adjust the legs so that the cabinet is level and does not wobble.
If seismic securement is required, the legs adjacent to the four casters can be bolted to the floor. See the
SIESMIC SECUREMENT section for details.
