ELECTRICAL CONNECTIONS

To bring power to this machine:

Loosen screw (A) Fig. 10, and remove cover (B) from terminal box located at the rear of the machine. Bring the power line up through the hole (C) Fig. 11, in terminal box. NOTE: Strain relief and power cord clamp are not supplied with the machine. Remove plastic shield (D) Fig. 11, from terminal strip (E).

THREE PHASE OPERATION

If the planer is wired for three phase operation, connect the three power lines to terminals (F), (G) and (K) Fig. 12, and the green ground wire to ground terminal (H).

IMPORTANT: FOR THREE PHASE MACHINES ONLY. After applying power to the machine, jog the power on and off to check if the cutterhead is rotating correctly. If the cutterhead is not rotating correctly, interchange any two of the three power lines connected to terminals (F),

(G) and (K) Fig. 12.

NOTE: The three phase motor is also capable of being wired for 440 volt operation, but this connection must be done by a qualified electrician and conform to the National Electric Code and all local codes and ordinances.

SINGLE PHASE OPERATION

If the machine is wired for single phase operation, there will be two power lines connected to the top terminals (L) Fig. 12. Connect the two incoming power lines to the corresponding bottom terminals (M) and connect the green ground wire to ground terminal (H).

22-451, 22-450 specifications

Delta 22-450 and Delta 22-451 are notable models within Delta's commitment to high-performance, precision woodworking tools. Designed for both amateur and professional woodworkers, these tools embody an ideal blend of innovation, usability, and durability.

One of the primary features of the Delta 22-450 is its powerful motor, which delivers reliable performance even under heavy workloads. This model is equipped with a 1.5 HP motor that ensures consistent power, allowing users to tackle various materials with ease. The motor is designed to operate quietly while minimizing vibrations, which enhances user comfort and precision during operation.

In contrast, the Delta 22-451 takes this a step further, boasting a slightly more robust 1.75 HP motor. This feature allows for increased cutting capacity and the ability to work with thicker and denser materials without bogging down. Both models come with a high-quality build, featuring cast-iron bases that provide stability and reduce vibration, further contributing to accuracy in cuts.

Another standout characteristic of the Delta 22-450 and 22-451 is their innovative fence system. Both models utilize a patented fence design that is easy to adjust and lock securely in place, providing users with confidence in their cutting precision. This technology makes repetitive cuts simple and accurate, which is invaluable when working on larger projects.

Additionally, safety is a key focus in the design of these tools. Delta has incorporated various safety features, such as blade guards and anti-kickback mechanisms, to protect users during operation. This attention to safety is crucial, especially for those who may be newer to woodworking or those operating in busy environments.

Furthermore, these models also feature a dust collection system that maintains a clean workspace. The integrated ports allow for connection to dust extraction systems, ensuring that the work environment remains clear of debris, which not only keeps the workspace safer but also improves visibility for more accurate work.

In summary, the Delta 22-450 and 22-451 are exceptional tools designed for both professional woodworkers and dedicated hobbyists. With powerful motors, advanced fence systems, robust safety features, and effective dust collection, these models are engineered to enhance the woodworking experience and deliver superior results. Their blend of reliability and innovative technology makes them worthwhile investments for anyone serious about woodworking.
