The 550.0121 power supply is for small installations. Care must be taken when using this power supply to make sure that the total load stays within 4 amps. The manual must be used to add up the power requirements of the installed circuit cards.

Testing the 550.0121 with a voltmeter:

A blinking light represents an overly high voltage

A solid light means there is voltage present not that the voltage is correct

The voltage may be checked by measuring between the ground and the voltage test point. Tolerances are + or - 5%.

The 550.0121 should power up with all green lights even when it is not plugged into the cabinet. 550 0121
