8. Upkeep, Maintenance and After-Sales Service
CAUTION
1. Only trained professionals are permitted to dismount, maintain or replace the parts and
components;
2. Prior to inspection and maintenance, please confirm that the inverter has been disconnected
from the power supply and that the voltage between P+ and N
－
is lower than 36V; otherwise
there may be hazards of electric shocks;
3. Do not leave any metal part, e.g. screws and washers, in the machine; otherwise there may be
hazards of equipment damage and fire;
4. After the control panel is replaced, set the relevant parameters prior to operation; otherwise,
there may be hazards of equipment damage.
8.1. Daily Upkeep and Maintenance
Inverters may break down as a result of ambient conditions (dust, damp and vibration, etc.) and aging
or deteriorating devices. Therefore, it is necessary to check a inverter and its operating environment at
regular intervals. It is a good idea to maintain a sound operating environment, keep daily operation
records and identify abnormalities as early as possible for an extended service life. Remember to check
the following points in daily maintenance of inverters:
1. Check if the operating environment conforms to the requirements;
2. Check if the operating parameters of the inverter are within the prescribed range;
3. Check if there is any abnormal vibration or noise;
4. Check if there is any abnormal smell;
5. Check if the fans are working well;
6. Check if the input voltage is within the prescribed range and if different phases have balanced
voltage?
8.2. Regular Maintenance
The user may check the inverter on a 3-month or 6-month basis, depending on the operating
environment. Generally, the following items must be checked:
1. Check if the screws for the control terminals have come loose;
2. Check if the main loop terminal has any poor contact and if the connection of copper bars has
marks of overheat;
3. Check if the power cables and control cables have any damage, especially scoring marks where
the cables are in contact with metal surfaces;
4. Check if the insulation bands on the cold-pressed terminals of the power cables have come off;
