Drawing-out port of lead wire
Card edge spacer
Enlarged drawing
Fix the lead wires with cord clamp
so that the lead wires do not slacken
at P.C board side. (2 positions)
Cord clamp
As shown in the figure, store PMV
lead wire connected with connector
assembly so that the connector
positions under wire of the terminal.
Details of PMV lead wire drawing
Fix the sensor lead wires firmly with the cord clamp
so that they do not touch with the caution plate of
the terminal block and they do not slacken at P.C.
board side. (3 positions)
Arrange the clamp at the position as shown in the
figure.
Cord clamp
Fold back the sensor lead wire and
fix it surely with the cord clamp.
Adhere on the transformer.

Details of sensor lead wire drawing
Be sure that the float switch
lead wire positions at inner side
of the fan motor lead wire.
Cord clamp
Fold back the float switch lead
wire and fix surely with cord
clamp. (There is no catching-
in of P.C. board and lead wire.)
Arrange at position as
shown in the figure.
