7.1.5 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.
2 Connecting the ground cable from the panel that houses control equipment to the 
panel to which the GOT is grounded
When running a single ground cable from the panel that houses such piece of control equipment as a 
sequencer to the panel to which the GOT is grounded, the ground cable may have to be directly 
connected to the terminal on the GOT.
If electric potential difference between the ground points created by it causes malfunctions, lowering the 
voltage as shown in Remedy 1 below may solve the problem.
