Á 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 
must be connected to earth ground. Consult factory for longer control signal cable length applications.
 This diagram shows three wire" control. Refer to the following page for diagrams of other control wiring methods.
