2000 125A Ferroresonant Rectifier J85502C-1
Issue 8 July 1999
Installation 5 - 17
5. Hold the meter selector switch in the RECT V position,
and use a small screwdriver to turn the OUTPUT VOLTS
ADJ potentiometer clockwise until the digital meter reads
approximately battery voltage, typically 26 volts for
24-volt plants or 52 volts for 48-volt plants.
6. Turn the DC OUTPUT circuit breaker On (up).
7. Adjust the OUTPUT VOLTS ADJ potentiometer to
obtain the desired initial charge voltage within the limits
specified in the preceding caution.
8. After completing the initial charge, turn the rectifier
POWER switch Off and the DC OUTPUT circuit breaker
Off (down).
9. If the rectifier has List WB (external high voltage
shutdown option), leave straps Q and T on CM1 in the
charge position (pins 1 and 2). If the rectifier is not
equipped with List WB, place Q and T in the normal
position (pins 2 and 3). Always move P14 back to its
normal pin 1-2 position when the initial charge is
completed.
10. Turn the OUTPUT VOLTS ADJ potentiometer fully
counterclockwise.
11. To restore the rectifier to service, follow the procedure in
Section 7 entitled “Restoring a Rectifier to Service.”
Warning
In the following step, DO NOT set the rectifier output voltage
to exceed 62 volts (48-volt rectifier) or 31 volts (24-volt
rectifier) or damage to the unit may result.
