    Chapter 2: Installation and Wiring Section 2.5 Field Wiring Connections Consider the following when wiring your system: General • Power and input wiring must be in accordance with Class 1, Division 2 wiring methods, Article 501-4(b) of the National Electric Code, NFPA 70, and in accordance with the authority having jurisdiction.

  • Page 23: Wiring Diagram

    Chapter 2: Installation and Wiring Noise Prevention • Route field wiring away from any other wiring and as far as possible from sources of electrical noise, such as motors, transformers, contactors, and AC devices. As a general rule allow at least 15.2 cm (6 in.) of separation for every 120 V of power.
