Ratings up to 206 Amps
❏ On units rated at 206A or less, connect the motor field lead F1 (+) to
A3TB4(F1+), and motor field lead F2 (-) to Field Control Module (F2–).
(Refer to Figure 5.)
❏ On units rated at 206A Iarm or less, connect armature voltage sensing lead
(A1) to Armature Interface PCB(A2) TB5-2(+), and connect armature
voltage sensing lead (A2) to Armature Interface PCB TB5-1(–).
(Refer to Figure 5.)

❏ On units rated 206A Iarm or less, connect the motor armature A1 lead
through contactor N.O. contact to fuse F4 (in a DSD 412) or terminal E5 (in
a DSD 406). (Refer to Figure 5.)
❏ On units rated at 206A Iarm or less, connect the motor armature A2 lead
through armature contactor N.O. contact to terminal ‘NEG’. (Refer to
Figure 5.)
