3.3 Output Checkout
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 checkout 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:
•
3 - 100 W /120 V light bulbs (use only one bulb for 4801iL)
•
3 - sockets
•
wires for connecting sockets to the unit
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 section 4.11. 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.
