Chapter 9 Maintenance
Many factors such as ambient temperature, humidity, dust, oscillation, internal component aging,
wear and tear will give rise to the occurrence of potential faults. Therefore, it is necessary to
conduct daily maintenance to the controller.
• If the controller has been transported for a long distance, please check whether the
components of the controller are complete and the screws are well tightened.

loose.
• Only a trained and qualified professional person can maintain the controller.
• Maintenance personnel should take off all metal jewellery before carrying out maintenance or internal
measurements in the controller. Suitable clothes and tools must be used.
• High voltage exists when the controller is powered up or running.
• Checking and maintaining can only be done after the controller’s AC power is cut off and wait for at least
10 minutes. The cover maintenance can only be done after ensured that the charge indicator inside the
controller and the indicators on the panel are off and the voltage between power terminals (+) and (-) is
below 36V.
• For the controller stored for more than 2 years, please use voltage regulator to increase the input voltage
gradually.
• Do not leave metal parts like screws or pads inside the controller.
• Do not make modification on the inside of controller without instruction from the supplier.
