• IF single-operator applicaon, PERFORM the following:
a. INSTALL one breakout status switch wire to terminal 9 of control box connector TB3.
b. INSTALL second breakout status switch wire to terminal 10 of control box connector TB3.
• IF dual-operator applicaon, PERFORM the following to put the breakout switches in series:
a. INSTALL one breakout status switch wire from one operator to terminal 9 of control box connector TB3.
b. INSTALL one breakout status switch wire from second operator to terminal 10 of control box connector TB3.
c. CONNECT remaining two yellow breakout status switch wires together with a wire nut.
