Carrier 09DK054-094 - Manual (Page 30)

NOTES:
1. Factory wiring is in accordance with National Electrical Code (NEC),
field modifications or additions must be in compliance with all ap­
plicable codes.
2. Wiring for field power supply must be rated 75 C minimum. Use
copper, copper-clad aluminum, or aluminum conductors. Maxi­
mum incoming wire size for each terminal block is 2/0.
3. Terminal blocks TB2, TB3, TB4, TBS, TB6, and TB7 are for
external field control connections. Control connections are to be
class 1 wiring.
4. Replacement of factory wires must be with type 105 C wire or its
equivalent.
5. Units are factory wired for a 50%/50% capacity split. If 100% ca­
pacity IS required, connect the factory-supplied jumpers from TB2-1
to TB3-1 and from TB2-2 to TB3-2. If jumpers are connected for
100% capacity, only one control power supply is required.
6. If a fan control kit is to be used, the jumper from TB2-1 to TB3-1
and the jumper from TB2-2 to TB3-2 must be connected. The
fan control kit is factory wired for a 67%/33% capacity split. If a
33%/33%/33% capacity split is required, remove the jumper from
TB4-1 to TB5-1 and from TB4-2 to TB5-2. If a 33%/33%/17%/17%
capacity split is required, remove the jumpers from TB4-1 to TB5-1
to TB7-1 and from TB4-2 to TB5-2 to TB7-2.
