Operation:

IMPORTANT! Please Read Before You Begin....
Setting the AC Line Voltage and Installing Fuses
Your ASE730 unit has been shipped from Thorlabs, Inc. configured for 115VAC operation. If you are planning to operate
your unit using a 220 / 230VAC input, or need to replace an open fuse, you must perform all or part of the following
procedure:
Setting the AC Line Voltage
- If it is attached, remove the AC line cord from the AC Input connector on the rear panel of the unit.
- Using a small screwdriver or similar tool move the LINE SWITCH actuator, on the rear panel, to either the "115V"
setting or the "230V" setting, whichever corresponds to your local commercial electrical service. The 115V
position allows operation from approximately 100VAC to 120VAC, while the 230V position allows operation from
approximately 200V to 250V.
Installing the AC Input Fuse
- If it is attached, remove the AC line cord from the AC Input connector on the rear panel of the unit.
Remove the existing fuse from the unit by pulling out the fuse holder, located in the bottom half of the AC Input
-
Module. This drawer will contain the existing fuse. It may be necessary to pry the drawer open with a small
screw driver. The drawer will remain attached to the module and cannot be completely removed.
- Remove the existing fuse from the fuse holder and insert the replacement fuse into the fuse holder. See Fuse
Replacement Information below for further information.
- Slide the fuse holder drawer back into the AC Input Module
Fuse replacement information
- For 115V operation use only 160mA 250V Type "T" fuse
- For 230V operation use only 160mA 250V Type "T" fuse
Power Connection
Only use a three pronged AC power cord; failure to provide an adequate earth ground may cause serious injury to
the user and possible damage to the instrument.
EXT MON Connector
The EXT MON connector located on the rear panel of the ASE730 is used only during the manufacture of the unit
and does not provide any user accessible functions. Improper connections made to this terminal will result in
permanent damage to the unit.
Warm Up
Connect an AC Line cord to the AC Input Module on the unit and to an appropriate AC outlet. Press the main switch on
the front panel. Allow the unit to warm-up for 1 hour prior to use.

Optical Connection

The ASE730 is supplied with an FC/PC output connector. Please keep this output connector covered with the attached
cap and chain when not in use.
Do not use an index matching gel with the ASE730. Typically, the use of an index matching gel will not improve the
coupling of our standard ultra-polished FC/PC connector. The use of a gel will very often lead to degradation of the
performance of the connection in that it effectively traps contaminants that will damage the physically contacting
connectors.
