Wire connection
REQUIREMENT
Connect the wires matching the terminal numbers. Incorrect connection causes a trouble.
Pass the wires through the bushing of wire connection holes of the Flow Selector unit.
Keep a margin (Approx. 100 mm) on a wire to hang down the electrical control box at servicing.
The low-voltage circuit is provided for the communication wires. (Do not connect the high-voltage circuit)
1
Loosen the cover mounting screws (2 positions) of the electrical control box, and then
remove the cover.
2
The cable clamp (accessory) is installed in the underside of the Flow Selector unit.
3
Connect the power supply wire and communication wire to the terminal blocks of the
electrical control box.
4
Tighten screws of the terminal block securely, and fix the wires with cord clamp attached
to the electrical control box. (Do not apply tension to the connecting section of the terminal
block.)
5
Mount the cover of the electrical control box so that it does not pinch the wires.
