DANGER
· There is possibility of danger to life due to electrical shock and high voltage.
· Do not touch non-insulated pas or cables.
· Disconnect the inveer from voltage sources and make sure it cannot be reconnected
before working on the device.
· Do not disconnect the DC connector under load.
· Do not touch the live pas and cables inside the inveer during operation, it might result
in burning or death.
· To prevent risk of electric shock during installation and maintenance, please make sure
that all AC and DC terminals are disconnected.
· Do not touch the suace of the inveer while the housing is wet, otherwise, it might
cause electrical shock.
· Do not stay close to the inveer while there are severe weather conditions including
storm, lighting, etc.
· Before opening the housing, the SAJ inveer must be disconnected from the grid and PV
generator; you must wait for at least ve minutes to le t the energy storage capacitors
completely discharged after disconnecting from power source.
WARNING
Danger to life due to re or explosion
· In the event of fault, do not conduct any direct action on the inveer.
· Disconnect PV array from inveer via an external disconnection device. If there is no
external disconnection device present, wait until no more DC power is applied to the
inveer.
· Disconnect the AC circuit breaker, or keep it disconnect if it is tripped, and secure it
against reconnection.
· Do not touch non-insulated pas or cables.
· Do not touch non-insulated pas or cables.
·The installation, seice, recycling and disposal of the inveers must be peormed by
qualied personnel only in compliance with national and local standards and regulations.
·Any unauthorized actions including modication of product functionality of any form may
cause lethal hazard to the operator, third paies, the units or their propey. SAJ is not
responsible for the loss and these warranty claims.
·The SAJ inveer must only be operated with PV generator. Do not connect any other
source of energy to the SAJ inveer.
·Be sure that the PV generator and inveer are well grounded in order to protect proper-
ties and persons.
CAUTION
·The solar inveer enclosure will become hot during operation. Please do not touch the
heat sink or enclosure during operation.
·Risk of damage due to improper modications.
·Public utility only.
·The solar inveer is designed to feed AC power directly to the public utility power grid; do
not connect AC output of the inveer to any private AC equipment.
