APPENDIX A
Section I. INSTALLATION PROCEDURE
Before you start...
1. Check the rear panel markings. If the factory settings are compatible with the available line voltage and frequency,
insert the desired plug-ins. Use the bail to raise the front of the instrument.
...go to Operating Instructions...
2. If a change is needed, follow these steps:
Use a proper power source. This instrument is designed to operate from a power source with its neutral
at or near ground potential with a separate safety-earth conductor. It is not intended for operation from
two phases of a multiphase system, or across the legs of a single-phase, three-wire system.
Avoid live circuits. Dangerous voltages exist at several points throughout this instrument. When the
instrument is operated with the cover removed, do not touch exposed connections or components. Some
transistors have voltages present on their cases. Disconnect power before cleaning the instrument,
changing line selector blocks, or replacing parts.
a. Line Selector Block(s)
Remove the five hold-down screws on the top of the dust cover cabinet and lift the cabinet off. This gives easy
access to the Line Selector blocks located on the main circuit board.
