TM 5-6115-593-12 TO 35C2-3-463-1 CAUTION When operating the breaker electrically, do not disconnect the voltage source until the motor operator arm has reached the end of its travel and stopped. (1) Disconnect    all    input    bars,    bussing, cables   and   control   circuits   to   breaker CB2.   The   circuit   breaker   should   be OPEN (OFF) or tripped position.  If not, cycle    breaker    to    OPEN    (OFF)    by connecting 120V AC to brown and white leads. (2) Using an ohmmeter, verify that all poles are   open   by   checking   for   continuity between line and load of each pole. (3) Verify   that   all   auxiliary   switches   are open   by   checking   between   each   pair (one  red  and  one  white  wire  in  tubing) and between both yellow wires. (4) Connect  24V  DC  (0.5  amp  or  greater) supply    to    under-    voltage    trip    (blue leads). (5) Cycle   breaker   to   CLOSED   (ON)   by connecting   120V   AC   supply   between yellow and white leads.  Wait for motor operator   arm   to   stop   moving   before disconnecting power source. (6) Verify    that    all    poles    and    auxiliary switches are closed (see steps 2 and 3, above). (7) Trip  breaker  by  removing  voltage  from undervoltage trip. (8) Check    that    all    poles    and    auxiliary switches are open. (9) Reconnect 24V DC supply to undervoltage trip (blue leads). (10) Reset  breaker  to  OPEN  by  connection 120V AC to supply between brown and white  leads.    Indicator  should  point  to OFF (OPEN). (11)    Turn breaker ON (CLOSED) by connection   120V   AC   supply   between yellow    and    white    leads.        Indicator should point to ON. (12)    Verify that all poles are closed. (13)    Turn breaker OFF (OPEN) by connecting   120V   AC   supply   between brown    and    white    leads.        Indicator should point to OFF. (14)    Verify that all poles are open. (15)    Disconnect all voltage supplies. (16)    Refer  to  next  higher  maintenance  for repair if necessary. d.  Installation. (1)   Install circuit breaker CB2 (44, figure 4- 12)  using  eight  screws  (43).    Connect buss  bars  (40,  41  and  42)  using  bolts (37)  and  screws  (35),  washers  (36  and 38) and nuts (39). NOTE Indicator     on     cover     shows     position     of operator arm and not motor operator drive, except when sequence is proper. CAUTION Manual   operation   of   circuit   breaker   CB2 can be achieved by removing operator arm retaining   device,   removing   operator   arm, and installing arm onto indicator hub nut.  If arm  is  to  be  manually  operated  from  OFF to ON (OPEN to CLOSED), the undervoltage    trip    (blue    leads)    must    be energized. (2)   Refer    to    figure    4-15    and    manually restore electrical sequence by removing operator     arm     retaining     device     and removing operator arm, then install arm onto  indicator  hub  nut  and  connect  a 24V   DC   (0.5   amp   or   greater)   power supply   to   the   undervoltage   tro[   (blue leads).    Manually  operate  the  breaker by moving the operator arm. 4-47
