Figure 5-7. Rotor Installation
Conduit Box Assembly.
Install bracket (19), if removed, in accordance with paragraph 5-7g.
Mount the conduit box assembly (32) using two guide pins used in paragraph 5-9, step (2), above, and
secure to the bracket (19) and coil assembly (33) with hexagon head screws (28) and mounting washers
(29). Remove the guide pins and install hexagon head screws (28) and mounting washers (29) in place of
the guide pins.
Install the main generator leads Ti through T6 on the wire support angles (6, Figure 5-2) as follows:
(a) Slide new heat shrinkable fittings on generator leads Ti through T6 before feeding the leads through the
wire support angles (6). Install the fittings such that the shrink sleeves are facing toward the generator coil
assembly (33, Figure 5-1). Do not heat shrink the fittings at this point.
(b) With shrink fittings installed, thread generator leads Ti, T4, and T6, left to right in that order, upward
through the mounting holes on the left wire support angle (6, Figure 5-2). Thread generator leads T2, T5,
and T3, left to right in that order, upward through the right wire support angle (6). Secure the heat
shrinkable fittings on the wire support angles with the mounting rings at the top.
(c) Individually adjust each generator lead by pulling upwards or downwards as necessary through the wire
support angles and fittings to assure that the generator lead insulation material does not chafe against
metal surfaces on the conduit box assembly (11) or the generator bracket (19, Figure 5-1), nor interfere
with armature rotation. Using a heat shrink device, heat each fitting as soon as this adjustment is made on
the corresponding generator lead. Tighten mounting rings on top of the angles until they are flush tight
against the wire support angle surface.
Install current boost transformers CT2 and CT3 in accordance with step d, below.
Current Boost Transformers CT2 and CT3.
Refer to Figure 5-2. Install current boost transformer CT2 or CT3 (5) and secure with hexagon head
capscrews (1), lockwashers (2), flat washers (3), and hexagonal nuts (4).
Reconnect wiring to transformers as tagged. Remove and discard tags.
Wrap generator lead Ti, three turns through current transformer CT3. Wrap generator lead T2 three turns
through current transformer CT2. Secure generator leads Ti, T4, and T6 together with tiewraps. Secure
generator leads T2, T5, and T3 with tiewraps. Connect terminal lugs of leads Ti, T2, and T3 to terminals of
load circuit breaker CB1 01 as shown in Figure 10-3. Generator lead Ti connects through load circuit
breaker CB1 01 to output line L1; lead T2 connects to output line L2; and generator T3 connects to line L3
via the circuit breaker.
Install tiewraps, as necessary, to secure leads in place along their length and to relieve stress at their lugs.
Reinstall rear cabinet B access panel.
