7. Wiring
(1) Terminals can be constituted by using solid wires, twisted wire, or crimp terminals.
When using the round crimp terminal, remove the terminal cover before wiring.
(2) For connectable wire size and tightening torque, refer to Table 7.1.

(Note 1) The flexible twisted wires cannot be used without sleeves.
As for using sleeves, crimp the sleeve (ferrule).
Twisted wire of 0.75 to 5.5 mm
2
(18 to 10 AWG): The number of wires must be seven or less.
Flexible twisted wire: The number of wires is larger than the above.
(Note 2) Use sleeves that comply with the DIN46228 standard.
• When using wire of 1.5 to 2.5 mm
2
(16 to 14 AWG), use sleeves with no insulation sheath.
• Depending on the crimping tool, there is a case where sleeves cannot be inserted into terminals.
Use the Phoenix Contact CRIMPFOX 6 or an equivalent crimping tool.
For the wire stripping length, follow the instructions provided by the sleeve manufacturer.
(Note 3) To comply with the UL and CSA standards, use the wire size of 14 AWG or 12 AWG.
And, use solid wires, twisted wires, or crimp terminals.
(Note 4) It is possible to connect two crimp terminals. (Figure 7.1) The length of wire protrusion must be
1 mm or less.
(Note 5) Tighten all the terminals including ones not wired.
(Note 6) When connected wires are bent for line arrangement after wiring, confirm again that the
tightening torque is appropriate.
