Wiring For Power Supply; Using External Power Supply - Mitsubishi F930GOT-BBD-K-E Installation Manual

Note:
Make sure to tighten the clamping bolts with a torque of 0.3 ~ 0.5 N# # # # m.

4. Wiring for Power Supply

Caution:
Cut OFF all phases of power source externally, before installation or wiring work in order to
avoid electric shock or damage to the product.
Note:
• When wiring the power supply, use electric wires of 0.75 mm
drop will not occur. For crimp-style terminals, use M3 size. Securely tighten crimp-style
terminals with a torque of 0.5 ~ 0.8 N#m so that errors will not occur.
• Insure correct termination of DC power source, incorrect connection may result in unit
failure or the GOT being burnt.
• Attach a fuse of 2 A to the 24V DC power supply.
• Perform grounding (100Ω or less) with an electric wire of at least 1.25 mm
Never perform common grounding of the GOT and a strong power system.
Note
• Feed power to the GOT by an external power supply.
The service power supply of the programmable controller cannot be used.
(Confirm service power supply capacity of main unit or extension unit is more than the total
value of the current consumption of GOT, extension blocks and special function blocks.)
• Even if instantaneous power interruption of less than 5 ms occurs, the GOT continues its
operation. When power interruption for considerable period of time or voltage drop occurs,
the GOT stops its operation. However, when the power supply is recovered, the GOT
automatically restar ts its operation. (The screen displayed just after recovery is
determined by the working environment originally set.)
