3.5  ELECTRICAL AND COMPUTER CONNECTIONS 
 
Before powering up the system for the first time, it is suggested to have a qualified electrician 
verify the wall socket to be used with the instrument  meets the requirements for operation as 
noted. 
 
Before making any electrical connections, verify the front panel power switch is in the off position 
for the monochromator. 
 
 
 
To avoid electric shock, connect the instrument to properly earth-
grounded, 3-
prong receptacles only.  Failure to observe this 
precaution can result in severe injury or death. 
 
The line voltage requirement is as follows: 
 
Monochromator Power Adapter  100 to 240 VAC, 47-63 Hz 
 
The monochromator conforms to CE standards for both safety and EMC.  During normal use, this 
equipment will not pose any electrical hazards to the user.  Read all warnings before installing or 
operating this system.  If there are any questions or concerns, contact Oriel Instruments or the 
regional sales representative for Newport. 
 
 
 
 
Never attempt to open the lamp power supply or monochromator 
power adapter.  These items do not contain any user serviceable 
parts.  Failure to follow this warning can result in severe injury or 
death. 
 
The monochromator’s power adapter connects to an AC wall socket and supplies DC voltage to 
the instrument. Do not open the monochromator cover and attempt to work inside without first 
turning the instrument off and disconnecting the power cord from the AC mains. 
 
The ribbon cable connecting the monochromator to the  optional  model  74010  filter wheel is 
installed before the system ships out.  The monochromator provides power to the filter wheel and 
allows the user to select which filter is placed in the optical path. 
 
Ensure the monochromator power switch is in the off position (marked as O).  Then connect the 
power adapter to the monochromator, as shown. Insert the power cord provided into the power 
adapter and connect to the AC mains. 
 
Connect the USB, RS232 or GPIB cable to the monochromator.  Plug the other end of the USB 
cable into the computer only after the TracQ Basic software is installed.
