Hitachi SJ700 Series Instruction Manual page 7

CAUTION: Be sure not to touch the surface or terminals of the SJ-EN Ethernet option board while
the inverter is energized; otherwise there is the danger of electric shock.
CAUTION: The software lock modes described in the SJ300 inverter manual are NOT supported via
the SJ-EN option board. 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-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-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.
INVERTER COMPATIBILITY
The SJ-EN Ethernet Interface option board is compatible only with SJ700, L700, SJ300 and L300P series
inverters. However, the parameters that can be accessed are different for the 700 and 300 series inverters. The
tables at the end of this manual show which parameters are accessible for each.
