Control Circuit Wiring Precautions
Observe
the following precautions when wiring control circuits.
• Separate
control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/T2,
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.
