and connectors are described, and then step-by-step instructions for connecting
and using the LDT-5412 are presented.
Installation
Before plugging the LDT-5412 into your AC power source, read this chapter. After
power-up, make sure that the OUTPUT is off (LED unlit) until you have set the
5412 for your application. For operating procedure, see the end of this chapter.
AC Power Considerations
The LDT-5412 can be configured for operation with nominal line voltages of 100,
120, 220, and 240 VAC. The unit is configured at the factory for the appropriate
range. Check to be sure that the correct range is marked on the rear panel. The
AC POWER switch is located on the front panel.
To avoid electrical shock hazard, connect the instrument to properly earth-grounded, 3-
prong receptacles only. Failure to observe this precaution can result in severe injury or
death.
