The wiring diagram for an controller generally spans multiple schematic sheets, covering everything from the main power supply to specific digital and analog input/output (I/O) connections.
: Shows the transformer and protection for the control voltage (e.g., 230V for IEC or 115V for CSA/UL standards).
A standard full wiring set for an Mk5-controlled system generally includes the following sections: acprodbponlinebcc5.blob.core.windows.net Power Circuit (Main Motor & Dryer):
