This section describes wiring to the GOT power supply section.
For the connection to a controller, refer to the following manual.
•GOT1000 Series Connection Manual for GT Works3 and a controller used
•GOT1000 Series Connection Manual for GT Designer2/GT Works2
For external dimensions of connection cable, refer to the following.

General preventive measures against noise
There are two kinds of noises: Radiated noise that is transmitted into the air and Conductive noise that is directly
transmitted along connected lines. Countermeasures must be taken considering both kinds of noises and referring
to the following 3 points.
(1) Protecting against noise
(a) Keep signal lines away from noise sources such as a power cable or a high-power drive circuit.
(b) Shield the signal lines.
(2) Reducing generated noise
(a) Use a noise filter, etc. to reduce the level of the noise generated due to a source such as a high-power
motor drive circuit.
(b) Attach a surge suppressor on the terminal of the molded case circuit breaker (MCCB), electromagnetic
contactor, relay, solenoid valve, or induction motor to supress the noise.
(3) Releasing noise to the ground
(a) Make sure to connect the ground cable to the ground.
(b) Use a short and thick cable to lower its ground resistance.
(c) Ground the power system and the control system separately.
WARNING
• Before starting wiring, always switch off the GOT power externally in all phases.
Not doing so may cause an electric shock, product damage or malfunction.
CAUTION
• Make sure to ground the FG terminal, LG terminal, and functional ground terminal of the GOT power supply
section with a ground resistance of 100 Ω or less solely for the GOT.
Not doing so may cause an electric shock or malfunction.
• Correctly wire the GOT power supply section after confirming the rated voltage and terminal arrangement of the
product.
Not doing so can cause a fire or failure.
• Tighten the terminal screws of the GOT power supply section in the specified torque range. Undertightening can
cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage of the screws or the GOT.
• Exercise care to avoid foreign matter such as chips and wire offcuts entering the GOT. Not doing so can cause a
fire, failure or malfunction.
