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.

Â This diagram shows three wire" control. Refer to the following page for diagrams of other control wiring methods.
