APPENDIX II

POWER ENTRY MODULE

This instrument uses a Corcom, Inc. M Series Power Entry Module that combines a power inlet, switch and fusing

system in one compact unit. The IEC 320 power inlet accepts any suitably terminated cordset. The ON/OFF switch

is DPST and has international I/O markings. The selectable fuseholder allows use of single or dual European fuses

or a single North American fuse. A voltage selector provides a convenient means to change transformer primary

connections to interface with worldwide power sources.

An exploded view of the power entry module with its components identified is shown below in Figure A-II-1:

Voltage selection:

The nominal voltage to which the power entry module is set is indicated by the indicator pin visible in one of the

holes adjacent the voltage markings.

To change selected voltage: open cover using a small blade screwdriver or similar tool; set aside cover/fuse block

assembly; pull voltage selector card straight out of housing using indicator pin; orient selector card so that desired

voltage is readable at the bottom; orient indicator pin to point up when desired voltage is readable at the bottom

(note that when the indicator pin is fixed; successive voltages are selected by rotating the card 90

 clockwise); insert

voltage selector card into housing,

printed side of card facing toward IEC connector and edge containing the desired

voltage first; replace cover and verify that the indicator pin shows the desired voltage.

Voltage selector card orientation is shown in Figure A-II-2.
