Power Supply Wiring - Mitsubishi Electric GOT1000 General Description Manual

6.2 Power Supply Wiring

• Make wiring connections to the power supply, I/O equipment and
power equipment separately by system as shown below.
When frequent noise is identified, connect an isolation
transformer.
Main power
• Twist 100V AC, 200V AC or 24V DC cable as closely as possible
and connect the cable of the minimum length between modules.
Also, use the thickest cable as possible (Max. 2mm
the voltage drop.
Use M3 solderless terminals and securely tighten them with a
tightening torque of 0.5 to 0.8N•m so that no problem will result.
• Separate the 100V AC, 200V AC or 24V DC cable from the main
circuit lines (high voltage, large current) and/or I/O signal lines.
Keep a distance of 100mm or more.
• As measures against surge due to lightning, connect a lightning
surge absorber as shown below.
