(Vector Controller)
This procedure is for the Vector Controller only.
The cable used in this procedure is:
• Rectifier Interface Cable Assembly 847690799 (10 feet) 
(provided with cabinet)
BLJ3 to BLJ3 (Vector Controller)
Step Action
1 Remove the GCM daughter board from the BLJ3 termination
board in the supplemental cabinet. It is not used with a Vector
controller in the initial cabinet.
2 Using 22-gauge wire (installer provided), make discrete alarm
connections from the terminals designated in Figure 6-7 on one
BLJ3 board to corresponding terminals on the BLJ3 board in
the next cabinet.
3 Connect the Rectifier Interface Cable Assembly from J5 of one
BLJ3 board to J6 of the BLJ3 board in the next cabinet.
Note: Remove and discard any resistors that are blocking
access to J6 or J5 connection points, except for those in J5 of
the first cabinet and J6 of the last cabinet.
4 If there is a battery shunt terminated onto the SH1+ or SH1–
terminals in the supplemental cabinet:
• Remove the WH strap from across an usused set of SH1 or
SH2 +/– terminals in the initial cabinet.
• Use 22 AWG (installer provided) to extend the shunt pair
from the supplemental cabinet to the unused SH1 or SH2
terminals on the BLJ3 termination board of the initial
cabinet.
Note: Vector monitor only 2 shunts maximum, SH1 and SH2.
