W/T3, , 1, 2, and 3) and other high-power lines.
• Separate wiring for control circuit terminals MA, MB, MC, M1, and M2 (contact outputs) from wiring to
other control circuit terminals.
• If using an optional external power supply, it must be a UL-listed Class 2 power supply source.
• Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating faults. Process
cable ends as shown in Fig 2.33.
• Connect the shield wire to terminal E (G).
• Insulate the shield with tape to prevent contact with other signal lines and equipment.
