OPTION
Recommended terminal shape
Terminal screws should be tightened to between 0.5 to 0.8N·m. Terminal screws must be secured to prevent a loose
connection thus avoiding a malfunction.
Do not tighten the terminal screw with a torque exceeding the specified torque. Failure to do so may cause
equipment failures or malfunctions.
7.1.3 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.
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.
