Power Supply Wiring - Mitsubishi GOT1000 GT15 User Manual

7.1 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.
Wiring diagram for power supply
• 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
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.

1. Separate the grounding of the lightning surge absorber (E1) from the grounding of
the GOT (E2).
2. Select an appropriate lightning surge absorber so that the supply voltage does not
exceed the maximum allowable circuit voltage of the surge absorber even when it
rises to the maximum.
