Hitachi SJ/L-EN Ethernet Communications Module Instruction Manual page 7

Chapter1
CAUTION: Be sure not to touch the surface or terminals of the SJ/L-EN Ethernet module while the
inverter is energized; otherwise there is the danger of electric shock.
CAUTION: The software lock modes described in the inverter manuals are NOT supported via the
SJ/L-EN module. This means that network commands can bypass any software lock settings
configured via the inverter keypad. It is incumbent on the user to make sure no safety lockouts are
violated through network commands.
CAUTION: When configuring parameters with the standard keypad, the inverter checks for and
inhibits invalid parameter combinations when the STR key is pressed. The SJ/L-EN bypasses this
check, so it is incumbent on the user to make sure invalid configuration parameters or combinations
are not sent through network commands. Otherwise undesirable inverter behavior may occur.
CAUTION: Certain parameter data ranges vary depending on model and capacity. The SJ/L-EN does
NOT check to make sure these data are within range. It is incumbent on the user to make sure data for
these parameters is within range for the specific model and rating. These parameters are noted in the
parameter tables in the Appendix. Otherwise undesirable inverter behavior may occur.
