MODELS

SJ200 AND L200, ¼ hp (0.2 kW) through 5 hp (3.7/4.0 kW),

SJ200CB-SB, SJ200CB-MB (CONDUIT BOXES)

The design of the front lower wiring terminal cover on the listed models of L200

and SJ200 has been improved, starting with June 2005 production. The purpose

of this change is to make opening of the cover easier. The new cover removal

method is shown below:

This upgrade necessitates that a design change be made to the corresponding

conduit boxes. The current conduit box design does not allow clearance for

removal of the new inverter cover. The existing conduit boxes will be

discontinued immediately. The new design will be universally compatible with

both the old and new design inverter. The new conduit boxes will be available

from Hitachi America stock starting in July 2005. Please order using the part

numbers in the table below.
