load/splitter interface assemblies as detailed in this section. Identify the affected reject load, possibly
named in an alarm reference and then replace it, as follows:
RF Drive Splitter A27 - accepts two of the six 5 kW reject power inputs (RF power modules 1-2 and
3-4) (see
“5 kW or 10 kW Reject Load Replacement” on page 4.1.55
)
4-Input Reject Load A29 - accepts four of the six 5 kW reject power inputs (RF power modules 5-6,
7-8, 9-10 and 11-12) (see
“5 kW or 10 kW Reject Load Replacement” on page 4.1.55
)
4-Input Reject Load A31 - accepts the three 10 kW reject power inputs (RF power modules 1-4, 5-8
and 9-12) (see
“5 kW or 10 kW Reject Load Replacement” on page 4.1.55
2-Input Reject Load A13 - accepts the 20 kW reject load power input (RF power modules 1-8) and
the final (30 kW) reject load input (RF power modules 1-12) (see
“Final Reject Load Replacement”
)
Reject Load/Splitter Interface Assembly (A28 and A30) - see
“Reject Load/Splitter Interface Assembly
5 kW or 10 kW Reject Load Replacement
.
NOTE
: 4-input reject load assembly A29 contains four of the six 5 kW reject load circuits. The remaining
two 5 kW reject load circuits are part of 20 kW RF drive splitter assembly A27. 4-input reject load A31
contains the 10 kW reject load circuits.
