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.
