User Manual
6
Even if all external power are disconnected, there still exists residual charge inside UPS, which
may endanger human life. It is necessary to set UPS aside for enough time (
≥10
min) to release
all charge before dismantling UPS.
As the battery doesn't isolate with AC input, there may exist dangerous voltage between battery
terminal and ground terminal. The battery pack should be insulated when installing or using it for
high voltage hazard concern.
Do not wear conductive objects, such as watches, bracelets and rings during operation.
The installer should have the operation qualification of high voltage and AC power. Maintenance
and repair for power system only can be done by qualified persons.
High leakage risk! Before performing electrical connection, device must be grounded.
Don't drill holes in the device! Inappropriate drilling will damage components inside device. Metal
debris generated by drilling entering device will lead to circuit board short circuit.
Any change of system configuration, structure or components will affect UPS performance. If the user
wants to make any change, please consult manufacturer in advance.
