About the DB-
25 Option
The D25KE DB-25 connector option is for use primarily with WESTERM
D20 KI interposing relay panels (part numbers 517-0146 and 517-0147LF).
For this connection use a multi-conductor shielded DB-25 cable assembly.
Note
Ensure that the multi-conductor cable’s shield drain wire is connected to pin
17 of the WESTERM D20 KI DB-25 connector.
Pin 17 of the D25KE DB-25 connector is not connected internally, and
therefore, cannot be used as a drain connection.
Note
For Trip/Close operation, the cables used to connect the D25 control outputs
to the D20 KI panels must have all DB-25 pins connected end-to-end.
• Use GE Grid Solutions part number 977-0208, or equivalent.
Trip/Close
Connections to
Interposing
Relay Panels
The D25KE module requires four WESTERM KI interposing relay panels to
support 32 pairs of Trip/Close digital outputs.
Note: For all KI relay panels, one of the Z1 jumpers must be installed to
provide a return path for the control voltage. KI panels have these
jumpers installed.
First group of eight digital outputs:
• Connect a DB-25 cable from J1 of the D25KE to J2 of the first WESTERM KI
interposing relay panel.
Second group of eight digital outputs:
• Connect a DB-25 cable from J2 of the D25KE to J2 of the second WESTERM
KI interposing relay panel.
Third group of eight digital outputs:
• Connect a DB-25 cable from J4 of the D25KE to J2 of the third WESTERM KI
interposing relay panel.
Fourth group of eight digital outputs:
• Connect a DB-25 cable from J5 of the D25KE to J2 of the fourth WESTERM KI
interposing relay panel
