➁ Do not exceed control wiring length of 15 meters (50 feet). Control signal cable length is highly dependent on
electrical environment and installation practices. To improve noise immunity the control terminal block common
must be connected to earth ground.
➂ This diagram shows “three wire” control. Refer to the following page for diagrams of other control wiring methods.
