slides in from the front.
Position the rack slide outer sections (item 1) so that the front edge is 35
mm behind the rack enclosure front flange. Tighten the fixings (items
7,8,9,10).
Install the analyser in the rack locating the inner slide section (item 1)
inside the outer slide section (item 1).
Secure the analyser into the rack cabinet using the screws (item 11) and
the plastic cup washers (item 12).

WARNINGS
• The installer must be satisfied that the Xentra 4900 installation conforms to
the relevant safety requirements, National Electrical Code and any other local
regulations, and that the installation is safe for any extremes of conditions
which may be experienced in the operating environment of the analyser.
• This appliance must be connected to a protective earth.
• No user serviceable parts inside. Enclosure protects against shock and
injury. Refer servicing to qualified personnel.
• To comply with the European Community EMC Directives for industrial
environments the interconnecting cables used for the mains supply, relay
contact outputs and/or analogue output signals should be screened or
provide equivalent protection.
Electrical power is connected to the chassis via an IEC appliance adaptor located on
the rear of the chassis.(see Figure 1.1). The xentra supplied will already be configured
for the mains voltage range ordered ('85 to 132V' or '170 to 264V').
The voltage setting may be changed as follows. The fuse value must be changed when
the voltage setting is changed:-
Unplug the mains connector (see Figure 1.1 )
Remove the voltage selector, a screwdriver may be used in the slot at the
top of the voltage selector to aid ejection.
Rotate the voltage selector through 180° so that the required voltage is
shown at the bottom of the voltage selector.
Fit fuse F2 to the right hand side of the voltage selector according to the
voltage selected. Voltage selector position 220/240V for 170 to 264V
