1-6. Replacing the Electrolytic Capacitor
The electrolytic capacitor used in this unit needs to be replaced periodically.
When a service for repair or maintenance is provided, and if the unit has been used for a long period of
time, it is recommended that the following electrolytic capacitor (or assembled part that include it) to be
replaced at once after having consent from the customer. Refer to Section A-3 for the part number of
replacing part.
The length of the operating life varies depending on the environment and conditions of how the part has
been used.
Make note that the part is not guaranteed for the number of years described below. It is served as a guide
for replacement.
Board Ref. No. Average length of name operating life
SY-365/365A C216 7 years
PS-757/757A SWR1 (AC-DC converter) 7 years
1-7. Lead-free Solder
Boards requiring use of lead-free solder are printed with a lead free mark (LF) indicating the solder
contains no lead.
(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particu-
lar size.)
: LEAD FREE MARK
m
.Be sure to use the lead-free solder for the printed circuit board printed with the lead free mark.
.The lead-free solder melts at a temperature about 40 dChigher than the ordinary solder, therefore, it is
recommended to use the soldering iron having a temperature regulator.
.The ordinary soldering iron can be used but the iron tip has to be applied to the solder joint for a
slightly longer time. The printed pattern (copper foil) may peel away if the heated tip is applied for too
long, so be careful.
