5.3 Connection of the Pump to the Power Supply Unit
NOTICE
Insert straight the control cable connector after checking its key direction. Inserting it in oblique
direction would cause damage of the connector pins. After the insertion, turn the cable connector
clockwise until the rotation lock clicks.
NOTICE
Don't disconnect each cable while the pump is running. Particularly before disconnecting the
control cable, Check complete shutdown of the pump by ROTATION lamp goes out and,
thereafter, turn off the POWER switch.
Control Cable:
Use the control cable that conformed CE marking. It has ferrite core at power supply side.
Control cables available for the use are identified with "262-75369A". But, If no ferrite core is not
fixed arround a control cable, it is not conformed CE marking.
Check that it is identified as specified. Even the use of other similar cable would disable start-
up of the pump, even though it could be connected. After turn on the POWER switch of the power
supply unit, ALARM lamp (Fig. 2-1 (14)) lights, if an old type cable is connected.
