● Only trained personnel are allowed to perform maintenance. Before performing
operations on the UPS, wear electrostatic discharge (ESD) clothes, ESD gloves,
and an ESD wrist strap. Remove conductive objects such as jewelry or watches
during operations to avoid electric shocks or burns.
● Use insulated tools when maintaining internal devices. Only trained personnel
are allowed to perform maintenance. Customers are not allowed to maintain
components behind protective covers that can be removed only using tools. If
the components are to be maintained, contact Huawei technical support.
● Only maintenance engineers can maintain power modules and bypass modules.
● Maintain UPSs regularly based on the following requirements. Otherwise, the
