6.8 Closing the SMA DC Disconnect
When you have finished connecting the DC input wires, the AC output wires and the fan power supply
recheck all the connections to ensure that everything is in the right place and that all connections and
knockout fittings are secure and properly torqued. Check all of the knockout fittings of the
SMA DC-Disconnect to ensure that they are in place.
1. Check wire routing to ensure that no wires can interfere with proper sealing of the cover and
that no pressure will be exerted on the connections when the cover is replaced.
2. Carefully position the cover on the front of the SMA DC-Disconnect.
– Make sure that the switch handle snaps into place.
– Make sure that the upper edge of the DC-Disconnect is covered by the lower edge of the
Sunny Boy.
– Make sure that the two screws in the cover are aligned correctly with the two threaded holes
in the enclosure.
3. While holding the cover in place, insert the two
screws into the threaded holes in the case and turn
them clockwise until they are hand-tight. Be careful
not to cross-thread any of the screws. Do not use
power tools to fasten the screws.
4. Verify that the cover is in the correct position.
5. Tighten the cover screws to a torque of 53 in-lbs.
(6 Nm).
