59 Certified Drawing CD: WSCWDC-MTII-WIRE-2 Job Name: Group: Chiller Type: WSC/WDC Effective: July 2007 Tag / Item No.: Supercedes: May 2006 WSC/WDC MicroTech II Wiring Diagram Notes NOTES: 1. Compressor motor starters are either factory mounted and wired or shipped separate for field mounting and wiring. If provided by others starters must comply with McQuay specification 359AB99. All line and load side power conductors must be copper. 2. If starters are free standing, then field wiring between the starter and the a terminal block located in the compressor motor terminal box is required. Minimum wire size for 115 Vac is 12 Ga. For a maximum length of 50 feet. If greater than 50 feet refer to McQuay for recommended wire size minimum. Wire size for 24 Vac is 18 Ga, all wiring to be installed as NEC Class 1 wiring system. All 24 Vac wiring must be run in separate conduit from 115 Vac wiring. Main power wiring between starter and motor terminal is factory installed when units are supplied with unit mounted starters. Wiring of free-standing starter must be wired in accordance with NEC and connection to compressor motor terminals must be made with copper wire and copper lugs only. When unit mounted starters are shipped loose for mounting on the unit in the field, a pre-wired control cable will be factory installed on the unit for connection to the starter in the field. 3. For optional sensor wiring see unit control diagram. It is recommended that dc wires be run separately from 115 Vac wiring. 4. A Customer furnished 24 or 120 vac power for alarm relay coil may be connected between utb1 terminals 84 power and 81 neutral of the control panel. For normally open contacts wire between 82 & 81. For normally closed wire between 83 & 81. The alarm is operator programmable, maximum rating of the alarm relay coil is 25va. 5. Remote on/off control of unit can be accomplished by installing a set of dry contacts between terminals 70 and Evaporator and condenser paddle type flow switches or water pressure differential switches are required and must be wired as shown. If field supplied pressure differential switches are used then these must be installed across the vessel and not the pump. 7. Customer supplied 115 Vac 20 amp power for optional evap and cond water pump control power and tower fans is supplied to unit control terminals (UTBI) 85 power / 86 neutral, PB equipment ground. 8. Optional customer supplied 115 Vac 25 VA maximum coil rated chilled water pump relay (EP 1 & 2) may be wired as shown. This option will cycle the chilled water pump in response to building load. 9. The condenser water pump must cycle with the unit. A customer supplied 115 Vac 25 VA maximum coil rated condenser water pump relay (CP1 & 2) is to be wired as shown. 10. Optional customer supplied 115 Vac 25 VA maximum coil rated cooling tower fan relays (CL - C4) maybe wired as shown. This option will cycle the cooling tower fans in order to maintain unit head pressure. 11. Auxiliary 24 Vac rated contacts in both the chilled water and condenser water pump starters must be wired as shown. 12. For VFD, Wye-Delta, and solid state starters connected to six (6) terminal motors the conductors between the starter and motor carry phase current and their ampacity must be based on 58 percent of the motor rated load amperes (RLA) times Wiring of free-standing starter must be in accordance with the NEC and connection to the compressor motor terminals shall be made with copper wire and copper lugs only. Main power wiring between the starter and motor terminals is factory installed when chillers are supplied with unit mounted starters, 13. Terminals 3 and 4 are for VFD only. NOTE: Voltage unbalance not to exceed 2% with a resultant current unbalance of 6 to 10 times the voltage unbalance per NEMA MG-1, 1998 Standard. Page 3 of 3
