4. Installation and Wiring of F920GOT-K/F930GOT(-K)/F940(W)GOT
Cautions on installation
• Use the F920GOT-K/F930GOT(-K)/F940(W)GOT in the environment for the general specifications
described in this manual.
Never use the F920GOT-K/F930GOT(-K)/F940(W)GOT in a place with dusts, soot, conductive
dusts, corrosive gas or flammable gas, place exposed to high temperature, condensation or wind
and rain, or place subject to vibrations and impacts.
If the F920GOT-K/F930GOT(-K)/F940(W)GOT is used in an unfavorable place described above,
electrical shock, fire or malfunction, damages or deterioration of the F930GOT/F940(W)GOT may
be caused.
• Never drop cutting chips and electric wire chips into the ventilation window of the F920GOT-K/
F930GOT(-K)/F940(W)GOT when you drill screw holes or perform the wiring work.
Otherwise, fire, failure or malfunction may be caused.
• Connect connection cables securely to the specified connectors while the power is turned OFF.
Imperfect connection may cause malfunction or failure.
Caution on wiring
• Make sure to shut down all phases of the power supply outside the F920GOT-K/F930GOT(-K)/
F940(W)GOT before starting the installation or wiring work.
Otherwise, electrical shock and damages of the F930GOT/F940(W)GOT may be caused.
Caution
• The F920GOT-K/F930GOT(-K)/F940(W)GOT has the DC power specifications. Connect the DC
power cable to dedicated terminals as described in this manual.
If the AC power supply is connected to power terminals, the F930GOT/F940(W)GOT may be
burnt.
• Mount and connect a fuse of 2 A to the 24V DC power supply. Connect the + and - sides of the
DC power supply correctly as described in this manual.
If the power supply is connected reversely, failure may be caused.
• Perform Class D grounding to the ground terminal ( ) of the F930GOT/F930GOT-K/F940(W)GOT
using a wire of 1.25 mm
2
or more.
When supplying the power from the PLC (excluding the F940WGOT), connect the F930GOT/
F930GOT-K/F940(W)GOT to the ground terminal of the PLC. When supplying the power from the
outside, connect the F930GOT/F940(W)GOT to the ground terminal of the external power supply.
However, never perform common grounding with the strong electrical system.
Caution on design
• While executing monitoring in the GOT (GOT-F900), if a communication error (including
disconnection of a cable) occurs, communication between the GOT and the PLC CPU is
interrupted and the GOT is disabled.
When establishing the system configuration using the GOT, make sure that a switch which gives
a significant operation to the system is executed from any equipment other than the GOT while
postulating communication error in the GOT. Otherwise, accidents may be caused by incorrect
output and malfunction.
Caution
• Do not bind the control cable and the communication cable together with the main circuit and the
power line. Keep such cables off the main circuit and the power line by 100 mm or more.
Otherwise, malfunction may be caused by noise.
• Make sure to press touch keys on the display screen with hand. If touch keys are subject to an
excessive force or pressed by a hard or sharp object, they may fail.
