When cutting input and ground con-
ductors to length, ground conductor
must be 26 inches (660 mm) long to
wrap around ground current sen-
sor. Note that ground conductor
must be insulated between strain
relief and ground terminal.
Insert input and grounding conduc-
tors through strain relief. Route
grounding conductor through reed
switch from right side of unit, under
switch, and through reed switch
again (two turns total) before con-
necting to ground terminal.
