NOTES
1.Three-pha motors protected against primary single phasing conditions.
2.Replacement of original wires must be with type 105° C wire or its equivalent.
3.Numbers on the right side of label diagrams indicate the line location of applicable contacts. An under-
lined number signifies normally clod contacts. A plain number denotes normally open contacts. Line numbers are shown on the left side of the diagrams.
4.Factory wiring is in accordance with National Electrical Code (NEC) U.S.A. Field modifications or addi-
tions must be in compliance with all applicable codes.
5.Wiring for main field power supply must be rated 75° C minimum. U copper for all units. Maximum
incoming wire size for each terminal block is 500 kcmil.
6.Power for control circuit should be supplied from a parate source (except 380, 380/415 v units)
through a field-supplied disconnect with 15-amp maximum protection for 115-volt control circuits and 15-amp maximum protection for 230-volt control circuit. Connect control circuit power to terminals 1 and 2 of TB4. Connect neutral side of supply to terminal 2 of TB4. Control circuit conductors for all units must be copper only. Control circuit power is factory wired for 380, 380/415-v units.
7.T erminals 13 and 14 of TB5 are for field external interlock connection for remote on-off and terminals 1
and 2 of TB5 for CWP interlock. Terminals 5 and 6 of TB2 are for CNP interlock and CNFS. The con-tacts must be rated for dry circuit application capable of handling a 24-v ac to 50 mA load.
8.T erminals 10 and 12 of TB5 are for control of chilled water pump starter. Terminals 11 and 12 of TB5
are for alarm. The maximum allowable load for each of the circuits is 75-va aled.豆角焖面的做法
9.T erminals 7 and 9 of TB2 are for condenr fan contactor A (HXA) or condenr water pump (HXC).
T erminals 8 and 9 of TB2 are for condenr fan contactor B (HXA). The maximum allowable load for each of the circuits is 360 va inrush, 75 va aled. Separate field power supply is not required.
