Installing a CTD-N End Cap Switch Kit
This section illustrates how to replace the original CTD-N end cap with a new end cap that contains
a shorting plug. The shorting plug allows the battery power to be connected and disconnected with-
out having to open the CTD-N.
The CTD-N End cap Switch Kit gives the user the ability to easily connect and disconnect the CTD-
N internal battery. The original 4-pin bulkhead is replaced with a 6-pin bulkhead connector. When
the 6-pin bulkhead is open or the dummy plug is connected there is no power drawn from the bat-
tery. Plugging in the Battery Shorting plug or the Battery Adapter cable draws battery power. If ex-
ternal power is applied the battery does not supply power.
Check Contents of Package
There are four different CTD-N End-cap Switch Kits. These kits differ only by the end-cap that is
supplied with each kit; all other contents are the same. Use Figure 43 to verify that the Switch Kit is
complete. If there are any parts missing call TRDI for a replacement.
