The CT5200D/DX is supplied without an electric plug, because it can use either
110V or 220V input.
When wiring in the plug:
Connect the yellow/green striped wire to ground
Connect the red and blue wires to the other two terminals in the plug
MAKE SURE THE CONNECTIONS ARE MADE CORRECTLY!
Only a qualified technician should do electrical wiring.
