2 Installing to Inverter (See Fig. 3)
2.1 Installation Procedure
1
Turn OFF the main power and wait for the time specified on the cover of the
inverter. Remove the cover and verify that the CHARGE indicator lamp is
OFF.
2
Insert the attached spacer (SRNT41028−9) into the spacer mounting hole
in the mounting base of the inverter. (See Fig. 3.)
Inverters of 3.7kW or smaller capacities have two closely placed holes. In-
sert the spacer into the hole on the 7CN side. Inserting into the wrong hole
will stack the spacer. Be careful to insert in the proper hole in the proper
inserting direction.
3
Align the two holes of PG−X2 and projections as shown in the detailed side
view, first at location (a) and then at (b), and precisely place the card on the
option A connector. Insert the spacer mounted at 2 above into the PG−X2
spacer mounting hole. (See part A of the side view.)
Verify that 4CN is precisely aligned to PG−X2. Gently push the card until
it clicks.
