Checkout Procedure
WARNING: LETHAL VOLTAGES. Ac sources can supply 425 V peak at their output. DEATH
on contact may result if the output terminals or circuits connected to the output are
touched when power is applied.
The output test requires that you connect light bulbs to the output of the unit and apply a
potentially hazardous voltage of 120 Vac. Properly shield all connections and wires.
The test in this section checks for output voltage and current on the ac source by having you connect light
bulbs to the output of the unit. The following equipment is recommended for performing this output
checkout procedure:
♦ 1 - 100 W light bulb
♦ 1 - light bulb socket
♦ wires for connecting socket to the unit
NOTE: When the ac source is turned on as shipped from the factory, it asserts the *RST state.
You can subsequently program the unit to turn on according to the state stored in *RCL
location 0, as explained in Chapter 4. The following procedures assume that the unit
turns on in the *RST state.
Make sure that the unit is turned off, and make the following connections to the output.
