Field Wiring Terminals

(Applicable if wire harness is not provided)

• Wire Range: 14 AWG Cu, stranded, for all terminals [Run Winding (R) and Active(T2)]
• Tightening Torque: 4.4 lbs-in [0.5 Nm] terminals.
• Field wiring conductors shall be rated 167°F [75°C]
• Suitable for use on a circuit capable of delivering no more than 5000rms symmetrical amperes, 120 volts maximum, when protected by a non-time delay RK5 fuse or circuit breaker rated 80A, or a time delay fuse rated 70A. The device does not provide current limiting control or equivalent.
• Suitable for use on a circuit capable of delivering no more than 5000rms symmetrical amperes, 240 volts maximum, when protected by a non-time delay RK5 fuse or circuit breaker rated 40A, or a time delay fuse rated 35A. The device does not provide current limiting control or equivalent.
• This soft starter is NOT an overcurrent protection device and must NOT be used as a replacement for any primary circuit overcurrent protection.

Installation Instructions

1. This product should be installed by a qualified technician.
2. Before installation turn off the HVAC system and ensure all electrical connections are off.
3. Verify from the manufacturer's wiring if there are any start-assist devices such as start capacitors, start relays, or PTCRs that may be present. If present, these need to be removed. Follow the Start winding connection from the compressor into the control box. This should terminate onto a run capacitor (HERM terminal, in case of a dual capacitor). If the same terminal has other wires terminated, these must be disconnected and electrically isolated.
4. Acquire the manufacturer's wiring diagram for the RV air-conditioning unit.
5. Open the top hood of the RV air-conditioning unit. If necessary, gain access to the compressor's wiring by removing any additional foam covers. [Illustration showing access to the RV air conditioner's compressor wiring.]
6. Identify the three wires (Run, Start, and Common) routed to the compressor. Most often, these are routed through a sleeve cover. [Diagram illustrating the three wires (Run, Start, Common) routed to the compressor, often through a sleeve cover.]
7. Identify a suitable location to place the soft starter. Use the 3M foam tape or mounting screws to attach it. Please avoid placing the soft starter and its wiring in the following areas:
   • In the direct path of an air vent.
   • In proximity (less than 2 inches) to copper pipes (inlet or discharge).
   • Near rotating mechanical parts.
   • Near heat sources.
   • A place that interferes with closing the top hood.
   [Illustration showing the soft starter being mounted using foam tape or screws, with a warning about placement near vents, pipes, moving parts, heat sources, or obstructions.]
8. Cut the compressor's three wires at a location within range of the soft starter's wire harnesses. Clearly identify the supply and compressor sides of the connections. [Illustration showing the compressor's three wires being cut within range of the soft starter's wire harnesses, emphasizing identification of supply and compressor sides.]
   [Wiring schematic illustrating the connections between the control box, soft starter (Supply Side: C, R, S; Compressor Side: C-OUT, R-OUT, S-OUT), and the compressor (C, R, S).]
9. Clearly identify the supply and compressor sides of the connections.
   • On the supply side, carefully match the run, start, and common wires of the A/C unit with the run, start, and common wires on the SUPPLY side of the soft starter. Strip each wire by 1/2" and terminate all 3 connections using closed-end splice connectors. See diagram below.
   • On the compressor side, carefully match the run, start, and common wires coming from the compressor with the run, start, and common wires on the COMPRESSOR side of the soft starter. Strip each wire by 1/2” and terminate all 3 connections using closed-end splice connectors.
   • Ensure that all 6 crimp connections are firm and secure.
   [Illustration showing the wiring connections on the supply and compressor sides of the soft starter, highlighting the use of closed-end splice connectors.]
10. Clean the chosen mounting surface for the soft starter. Then use the zip ties to ensure that the wire harness on both sides is securely routed inside the unit. [Illustration showing the soft starter mounted and zip ties used to secure the wire harness.]
11. Securely replace any foam covers and the top hood. Turn on the power and verify the operation.
