2000 100A Ferroresonant Rectifier J85503A-1
5 - 14 Installation
Issue 6 October 1998
The rectifier is now installed. The last three sections in this
chapter are optional procedures that may be needed at
installation. If not, proceed to Section 6, Testing.
Converting AC
Voltage
Converting the ac input voltage to a rectifier is necessary only if
the ac wiring is incorrect in the unit or if rectifiers are moved and
the input ac voltage is different. Refer to Figure 5-3 during this
procedure. Also see note 18 on J-drawing, J85503A-1.
Table 5-C is used for both 208 to 240-volt ac and 240 to 208-volt
ac conversions. Use the half of the table (top or bottom) that
starts with the desired input line voltage.
This procedure is accomplished in two parts. The first is to
install on the K1 contactor the alternate set of three ac leads
(from the six bundled wires) for the new ac input voltage (208 or
DANGER
This procedure MUST be performed ONLY on a rectifier
completely disconnected from the battery and plant bus, AND
with ac power disconnected at the ac service panel.

Note: The wires in the second column are from main transformers T1 and T2 and
are all bundled together between T1 and T2. Three wires (the ones for the current
input line voltage) pass behind the relay shield and go up to the K1 contactor. The
other three are taped and remain in the bundle. The numbers following the T1 and
T2 designations in the second column are the numbers marked on the bundled
wires. Do no be confused by the T1, T2, and T3 designations following K1; these
refer to the K1 contactor terminals, not the transformers.
