NOTE: For operating sequence, refer to the Controls, Start-Up,Operation, Service, and Troubleshooting literature.GENERALThis publication contains Wiring Diagram information forthe 30RB060-390 air-cooled liquid chillers with electroniccontrols. These chillers are equipped with ComfortLink controls and electronic expansion valves.NOTE: Unit sizes 315-390 are modular units that are shippedin separate sections as modules A or B as noted in position 8 ofthe unit model nomenclature. See Table 1 for a listing of unitsizes and modular combinations.NOTE: The nameplate for modular units contains only the firsttwo digits in the model number. For example, 315A and 315Bname plates read 31A and 31B.SAFETY CONSIDERATIONSInstalling, starting up, and servicing this equipment can behazardous due to system pressures, electrical components, andequipment location (roof, elevated structures, etc.). Onlytrained, qualified installers and service technicians shouldinstall, start up, and service this equipment. When working onthis equipment, observe precautions in the literature, and ontags, stickers, and labels attached to the equipment, and anyother safety precautions that apply. Follow all safety codes.Wear safety glasses and work gloves. Use care in handling,rigging and setting this equipment, and in handling all electrical components.Table 1 — Modular Unit CombinationsMODULAR NGElectrical shock can cause personal injury and death. Shutoff all power to this equipment during installation andservice. There may be more than one disconnect switch.Tag all disconnect locations to alert others not to restorepower until work is completed.MODULE A30RBA16030RBA17030RBA17030RBA19030RBA190MODULE B30RBA16030RBA16030RBA17030RBA17030RBA190NOTE: An “A” in the fifth position of the model number indicates thedesign series.2

Field modifications or additions must bein compliance with all applicable codes.Wiring for main field supply must be rated 75 C minimum. Use copper for all units.Incoming wire size range for the terminal block is no. 4 American Wire Gage (AWG) to 500 kcmil.Incoming wire size range of non-fused disconnect with Minimum Circuit Amps (MCA) up to 599.9 amps is 3/0 to 500 kcmil.Incoming wire size range of non-fused disconnect with MCA from 600 to 799.9 amps is 1/0 to 500 kcmil.Incoming wire size range of non-fused disconnect with MCA from 800 to 1199.9 amps is 250 to 500 kcmil.Terminals 9 and 10 of TB5 are for field external connections for remote on-off. The contacts must be rated for dry circuit application capable of handling a 24 vac load up to 50 mA.Terminals 1 and 2 of TB5 are for external connections of chilled water pump interlock. The contacts must be rated for dry circuit application capable of handling a 24 vac load up to 50 mA.Terminals 11 and 13 of TB5 are for control of chilled water pump 1 (PMP1) starter.Terminals 13 and 15 of TB5 are for control of chilled water pump 2 (PMP2) starter.The maximum load allowed for the chilled water pump relay is a 5 va sealed, 10 va inrush at 24 v. Field power supply is notrequired.For control of chilled water pumps, a set of normally open contacts rated for dry circuit application must be supplied from fieldsupplied pump starter relay. Connect contacts to violet and pink wires in harness from main base board channel 18. Wires inharness are marked PMP1-13 and PMP1-14.Terminals 12 and 13 of TB5 are for an alarm relay. The maximum load allowed for the alarm relay is 10 va sealed, 24 va inrushat 24 v. Field power supply is not required.Make appropriate connections to TB6 as shown for energy management board options. The contacts for occupancy override,demand limit and ice done options must be rated for dry circuit application capable of handling a 24 vac load up to 50 mA.3
