MRK (Motor Replacement Kit)
The current "MRK" kit includes an MA-ND5 motor.  It uses three wires to power open or to power close.  The EWC Controls motor actuators have seen many design changes over the years.  Models MA-ND3 (blue case) and MA-ND3B (orange case) are obsolete.  Models MA-ND4 and MA-ND5 (grey cases with clear covers) are current.   All of these models have identical wiring and installation instructions.  Please refer to the documentation for the MA-ND5 for any of these models.  The current "MRK" kit will replace any MA-ND3, MA-ND3B, MA-ND4, or MA-RDN.
