2000 125A Ferroresonant Rectifier J85502C-1
8 - 4 Spare Parts and Replacement Procedures
Issue 8 July 1999
•
When soldering static-sensitive semiconductor devices, the
soldering iron must be grounded to the work table which
must also be earth grounded.
•
Do not wax the equipment aisles in central offices.
•
Whenever possible, maintain relative humidity above the
20-percent level.
Modifying the
CM1 Option
Board
As described in schematic drawings SD-82659-01, replacement
CM1 option boards are supplied with all wire straps and
resistors in place. The same wire straps and resistors that were
removed from the original board must be removed from
replacement boards in order for the rectifier to operate properly.
Table 8-B and Figure 6-2 show the straps and resistors to keep
and to remove from the CM1 board for each option on the
J85502C-1 rectifier. The plug-in type wire straps are removed
completely from a 2-hole jack. The other wire straps shown are
soldered in and are never replaced once they are removed.
