Precautions for Correct Use
• Use cables with suitable wire sizes for the carrying current. There are also restrictions on the
current due to the ambient temperature. Refer to the manuals for the cables and use the
cables correctly for the operating environment.
• Double-check all switches and other settings and double-check all wiring to make sure that
they are correct before turning ON the power supply.
Use the correct wiring parts and tools when you wire the system.
• For twisted wires, strip the sheath and twist the conductor portion. Do not unravel or bend the
conductor portion of twisted wires or solid wires.
If more than 2 A will flow on the wires, use plated wires or use ferrules.
