7.1 General Check
(1) Make sure that the field-supplied electrical components (main power switches, circuit breakers,
wires, conduit connectors and wire terminals) have been properly selected in accordance with local
laws and regulations.
(2) Check to ensure that the power supply voltage is within ±10% of the rated voltage.
(3) Check the capacity of the electrical wires. If the power source capacity is too low, the system cannot
be started due to the voltage drop.
(4) Check to ensure that the ground wire is connected.
(5) Power Source Main Switch
Install a Power Source Main Switch in accordance with relevant local laws and regulations. The distance
between switch contacts should large than 3.5mm when the switch is off.
