THE ELECTRICAL INSTALLATION.
Internal Components and circuit boards (except the isolated I/O terminals)
carry high voltage when the RCU Regenerative Converter is connected to the
main power supply and/or inverter DC bus. This voltage is extremely
dangerous and may cause death or severe injury if you come in contact with it.
When the RCU Regenerative Converter is connected to the main power,
current is flowing in the AC line connection (R (L1), S (L2), T (L3)) and the
inverter's DC-Link (P, N).
The voltage on the RCU components is extremely dangerous and may cause
death or severe injury if you come in contact with it.
The control I/O terminals are isolated from the main voltage, but the relay
outputs and other I/O terminals may have dangerous voltage connected even if
the power is disconnected from the RCU Regenerative Converter.
The installer of the RCU Regenerative Converter is responsible to ensure it is
installed with appropriate main switches or disconnects, and appropriate power
fusing.
Spare parts and service should only be obtained through Hitachi America, Ltd.
