10. Connect power tap conductors to unit main control
box.
a.
Single point boxes with two or three tap con-
ductors--Route the tap conductors (with bushing
added per Step 5) into the unit main control box.
Connect the
power tap conductors to the desig-
nated terminals in the unit’s control box for field
power connections. Refer to the wiring diagram
in the unit, to unit installation instructions for
Field Power Wiring Connections or to Appendix
A, B or C.
b. Single point boxes with six tap conductors
(CRSINGLE043A00, 045A00, 049A00, 051A00,
053A00 and 054A00)
These single point boxes include two sets of
three-lead power tap conductors connected to
two separate fuse blocks, at FU2 and F
U3.
These kits also include two terminal blocks
(TB10A and TB10B) and attachment screws; the
TB10 block usage will be two, one or none,
basedonbaseunit.
Refer to TB10 usage tables on page 9 to
determine quantity required for this unit.
(1.) Units requiring TWO TB10 terminal blocks
Mount these terminal blocks in the unit’s
control box next to compressor contactor
C1. (See Fig. 10 and Appendix A or C.)
Locate two 42--in (1067 mm) BLU and YEL
wires with single insulated female terminal
shipped in a bag with this kit.
At the single point box, locate the BLU tap
conductor on fuse block FU2 (upper block);
disconnect and discard. Connect the 42--in
BLU wire to FU2.
At the single point box, locate the YEL tap
conductor on fuse block FU3 (second block);
disconnect and discard. Connect the 42--in
YEL wire to FU3.
In the unit control box, relocate these wires:
At IFC terminal 13, disconnect Compressor 1
BLU and Compressor 2 ORN leads; reconnect
at TB10A. At C1 terminal 13, disconnect ID
Fan YEL lead; reconnect at TB10B. At C1
terminal 11, disconnect BLK jumper;
reconnect to IFC terminal 11.
Route the first set of tap conductors (attached
at upper fuse block, with bushing per Step 5)
into the main control box; connect at:
BLK: C1 terminal 11
YEL: C1 terminal 13
BLU (long lead with terminal): TB10A
Route the second set of tap conductors
(attached at second fuse block) into the
main control box; connect at:
BLK: IFC terminal 11
YEL (long lead with terminal): TB10B
BLU: IFC terminal 13
(2.) Units requiring ONE TB10 terminal block
Locate two 42--in (1067 mm) BLU and YEL
wires with single insulated female terminal
shipped in a bag with this kit.
At the single point box, locate the BLU tap
conductor on fuse block FU3 (second block);
disconnect and discard. Connect the 42--in
BLU wire to FU3.
Mount one TB10 terminal block in the unit’s
control box between compressor contactors
C1 and C2. (See Fig. 10.)
Relocate these wires:
At IFC terminal 13, disconnect Compressor
2 ORN and OFM BLU leads; reconnect
at TB10.
Remove these leads:
At C1-11, remove BLK jumper to C2-11.
Discard.
At C1-13, remove YEL jumper to C2-13.
Discard.
Route the first set of tap conductors
(attached at upper fuse block, with bushing
per Step 5) into the main control box;
connect at:
BLK: C1 terminal 11
YEL: C1 terminal 13
BLU: IFC terminal 13
Route the second set of tap conductors
(attached at second fuse block) into the main
control box; connect at:
BLK: C2 terminal 11
YEL: C2 terminal 13
BLU: TB10
