CAUTION
ATESS HPS50 can only be stored when it is stopped and all
the doors are closed in a dry room to protect the internal
circuits against dust and moisture.
2.4 . Transportation
Transportation should follow the transportation methods described in the user
manual. The inverter's weight and center of gravity should be taken into account
during transportation. The center of gravity is marked on the box.
DANGER
During transportation, lifting equipment and personnel must be
qualified. The inverter should be placed vertically and the
inclination cannot be more than 10 degrees. It is not allowed to
place the inverter upside down or transport in a horizontal
position. Incorrect lifting and transportation can lead to serious
injury, property loss and damage to the inverter.
Caution, risk of danger
Repair and maintenance can only be carried out after disconnecting the DC and
AC for at least 5 minutes.
Only professional technical personnel are qualified for the operation.
Maintenance and modification
Only personnel with ATESS authorization are qualified for the maintenance and
modification. And to ensure personal safety, use original accessories provided by
the manufacturer only. Otherwise, electrical safety and EMC might not comply with
the required standard.
Function and safety parameters
Don't change the parameters of the inverter without authorization from the local
utility and ATESS Energy Technology Co., Ltd. Otherwise, it might lead to injury or
equipment damage and the warranty of the inverter will be voided.
Risk of electric shock, Energy storage timed discharge.
WARNING
Electrical shock danger exists in the capacitor; the cover
shall be moved at least 5 minutes later after all powers are
disconnected.
2.6 . Inverter EMC and noise level
Electromagnetic compatibility (EMC) is the requirement for electrical equipment
that it can operate normally in the electromagnetic environment and does not
cause unacceptable environmental impact itself.
Disconnecting switches
Disconnect DC switch and AC switch, and make sure the inverter will not be
connected accidentally. Ensure the inverter is totally disconnected with no voltage
by testing with a multi-meter. Although the DC and AC switch has been
disconnected, there is still voltage in some components, for example capacitors.
Hence, the repair or maintenance operation can only be proceeded at least 5
minutes after the disconnection.
2.5 Repair and maintenance
2.2. Operator
Inverter installation and service personnel must be trained and familiar with the
general safety requirement when working on electrical equipment. Installation and
service personnel should also be familiar with the local laws and regulations and
safety requirements.
2.3. Inspection and storage
The inverter should be carefully checked before signing the document from the
transportation company. Check the received items against delivery note, and if
there is any defect or damage, immediately notify the transportation company. If
necessary, you can seek help from ATESS Customer Service department.
