• Carry out the independent grounding if possible.
• If the independent grounding is impossible, carry out the shared grounding as shown in fig.2) below.
• Use the cable of 2mm
2
or more for grounding.
Set the grounding point closer to the GOT to make the grounding cable short as possible.

7.1.2 The cause of malfunctions related wiring/Remedy
Grounding of the GOT may cause electric potential difference and noise interference, which may result in
GOT malfunctions.
These problems may be resolved by taking the following measures.
1 Wiring path of the GOT's ground cable and power line
Bundling the GOT's ground cable and power line together can cause interference noise, which may
result in malfunctions.
Keeping the GOT's ground cable and power line away from each other will help minimize noise
interference.
