If an externally wired latch check switch and a motor operator are installed
together, a simple secondary wiring change must be made. Remove the latch
check switch’s secondary connector plug as described in Section 9. Once
removed, disconnect the latch check switch’s secondary lead (#39-NF, #51-RF)
from the connector plug by inserting the terminal extraction tool (included in
the externally wired latch check switch kit) into the end of the connector plug
as shown. The tool releases the lead so it can be removed from the other end.
The connector plug can be discarded. The latch check switch’s disconnected
lead (#39-NF, #51-RF) is now reconnected into the open secondary location
in the motor operator’s connector plug. No tool is required to make this
connection. It is, however cautioned that the connector plug must be oriented
as shown in Figure 26 before making the connection. Gently push the lead into
the connector’s open spot, and it will easily connect and lock into place.
