NOTES:

1.Factory wiring is in accordance with UL 1995 standards. Field modifications or additions must be in compliance with all applicable codes.

2.All units or modules have single point primary power connection. Main power must be supplied from a field or factory supplied disconnect.

3.Wiring for main field supply must be rated 75 C. Use copper conductors only.

a. Incoming wire size range for terminal block with MCA up to 120 amps is 14 AWG (American

Wire Gage) to 2/0.

b. Incoming wire size range for terminal block with MCA from 120.1 amps to 310 amps is 6 AWG to 350 kcmil.

c.Incoming wire size range for non-fused disconnect with MCA up to 50 amps is 10 AWG to 2 AWG.

d.Incoming wire size range for non-fused disconnect with MCA from 50.1 amps to 90 amps is 6 AWG to 3/0.

e.Incoming wire size range for non-fused disconnect with MCA from 90.1 amps to 250 amps is 4 AWG to 350 kcmil.

4.Refer to certified dimensional drawings for exact locations of the main power and control power entrance locations.

5.Terminal 24 of the LVT is for controlof chilled water pump (CWP) starter. Terminal 20 of the LVT is for control of condenser pump (CNP) starter or condenser fan relay (CFR). The maximum load allowed for the relays is 5 VA sealed. 10 VA inrush at 24 VAC. Field power supply is required.

6.Terminal 25 of LVT is for an alarm relay. The maximum load allowed for alarm relay is 5 VA sealed, 10 VA inrush at 24 VAC. Field power supply is not required.

7.Make approprate connections to LVT as shown for energy management board options. The con- tacts for demand limit and ice done options must be rated for dry circuit application capable of han- dling 24 VAC load up to 50 mA. Installation of optional energy management board required.

8. Remove jumper between terminals 16 and 17 when field chilled water pump interlock (CWPI) is installed.

9.Terminals 18 and 19 of LVT are for floating point control of condenser water valve (CWV). Teminal 18 commands valve closed. Terminal 19 commands valve open. The maximum load allowed for condenser water valve is 5.5 VA at 24 VAC. Field power supply is not required.

30MPA specifications

The Carrier 30MPA is a prominent industrial chiller unit known for its outstanding performance and efficiency in cooling applications. Designed for mid-sized commercial and industrial facilities, it exemplifies cutting-edge technology and engineering.

One of the main features of the Carrier 30MPA is its advanced scroll compressor technology. This innovative design allows for improved efficiency and reduced energy consumption compared to traditional chiller units. The compressors are known for their reliability and quiet operation, making the 30MPA ideal for environments where noise is a concern.

The unit employs a high-efficiency economizer mode, which optimizes energy use during cooler ambient conditions. By utilizing outside air for cooling, the economizer significantly reduces the chiller's energy demand, promoting sustainability and cost savings.

Additionally, the 30MPA is equipped with a microprocessor-based control system. This intelligent control technology allows for precise monitoring and adjustment of system performance, enhancing both comfort and efficiency. The controls come with various customizable settings, enabling users to tailor the chiller's operation to meet specific needs.

The 30MPA also stands out with its robust construction and design. It features a compact footprint, allowing for easy installation in confined spaces. Its weather-resistant casing and corrosion-resistant components ensure durability and long service life, even in harsh environments.

Moreover, the Carrier 30MPA incorporates an environmentally friendly refrigerant, which complies with global regulations aimed at reducing ozone depletion and greenhouse gas emissions. This commitment to environmental responsibility aligns with Carrier's goal of promoting sustainable building practices.

Another important characteristic is its flexible configuration options. The unit can accommodate different system designs and requirements, making it suitable for a wide range of applications, from chilled water systems in hospitals to comfort cooling in office buildings.

In summary, the Carrier 30MPA chiller combines innovative technology, energy efficiency, and robust design, making it a standout choice for commercial and industrial cooling applications. Its advanced features and sustainable approach not only ensure reliable performance but also contribute to lower operational costs and reduced environmental impact.
