● Do cut off input and output power, and wait at least 15 minutes until the power
indicator is off before further operation.
● Ensure that the motors, cabinets, and other components are installed and
connected in accordance with the national technical rules and other applicable
regional regulations. Pay special attention to regulations on cable dimensions,
fuses, grounding, open circuits, isolation, and overcurrent protection.
● If the safety device trips in a branch circuit, the fault current may have been
disconnected. To reduce the risk of fire and electric shocks, check the conductive
parts and other components of the cabinet and replace the damaged ones. Find
the cause of the tripped fuse and make sure the problem is solved.
