Components
The SJ300 Series inverters have a detachable keypad (called a digital operator) on the front
panel of the housing. The particular keypad that comes with the inverter depends on the
country or continent corresponding to the particular model number. The standard digital opera-
tors occupy just part of the keypad recess in the panel. Therefore, the inverter comes with a
snap-in panel filler plate that mounts below the keypad as shown.
These detachable keypads can be mounted in a NEMA cabinet panel door cut-out, for example.
Threaded metal inserts on the rear of the keypads facilitate this external mounting configura-
tion. A short cable then connects the keypad unit to the connector in the inverter keypad recess.
See Chapter 3 for information on how to install and use these keypads and cables.
The digital operator / copy unit is optional, and
occupies the entire keypad recess when mounted. It
has the additional capability of reading (uploading)
the parameter settings in the inverter into its memory.
Then you can install the copy unit on another inverter
and write (download) the parameter settings into that
inverter. OEMs will find this unit particularly useful,
as one can use a single copy unit to transfer parame-
ter settings from one inverter to many.
Other digital operator interfaces may be available
from your Hitachi distributor for particular industries
or international markets. Contact your Hitachi
distributor for further details.
