*Field-supplied.
NOTES:
1. Factory wiring is in accordance with NEC; field modifications or addi-
tions must be in compliance with all applicable codes.
2. Wiring for field power supply must be rated 75 C minimum. Use cop-
per,copper-cladaluminum,or aluminumconductors.Maximumincom-
ing wire size for each terminal block is 500 kcmil.
3. TerminalblocksTB3,TBX1,andTBX2areforexternalfieldcontrol con-
nections. Control connections are to be Class 1 wiring.
4. Field-supplied components (IFC, LLS-A1, and LLS-A2) must have a
maximum sealed coil rating of 30 va each (0.25 amp at 120 vac,
13 amp at 230 vac). AHMS IFC-AUX must have minimum pilot duty
ratingof400 vaeach(3.4amps at120vac,1.8 ampsat230vac)each.
5. Replacement of factory wires must be with type 105 C wire or its
equivalent.
6. Field-suppliedliquidlinesolenoidvalves installedattheevaporator are
required on all units.
7. Control has 175 va of power available for field-installed accessories.
