What is the correct method for wiring the control circuit terminals?

For control circuit wiring, strip off about 10mm of the wire sheath and use blade terminals or single wires inserted directly into sockets. Use recommended wire sizes of 0.3mm² to 0.75mm², with maximum wiring length of 30m. Use shielded or twisted cables and keep them away from main and power circuits. Do not solder wires, and do not short across terminals +24 and SD. (Pages 13-14)
