o Connect an ammeter in the supply circuit of the power supply. A range of about 1 A
for the meter is appropriate.
o Close the protective switches to apply voltage to the power supply. The measured
steady state current should be insignificant. Transient movement of the ammeter
merely indicates the charging current of capacitors.
o Check the polarity and magnitude of the voltage at the device terminals.
o Power consumption by the power supply should be in accordance with the quiescent
specification.
o Remove the voltage from the power supply by opening the protective switches.
o Disconnect the measuring test equipment; restore the normal power supply connec-
tions.
o Apply voltage to the power supply.
o Close the protective switches for the voltage transformers.
o Verify that the voltage phase rotation at the device terminals is correct. Note that the
device can be set for ABC rotation or ACB rotation under Address 3+$6(
6(4in 36\VWHP'DWD. See also Sub-section 6.1.1.
o Open the protective switches for the voltage transformers and the power supply.
o Check the trip and close circuits to the power system circuit breakers and the other
primary equipment that is to be controlled by the 7SJ62.
o Verify that the control wiring to and from other devices is correct.
o Check the signalling connections.
o Close the protective switches to apply voltage to the power supply.
