Safety device
• This circuit must be protected with the required safety devices like a main switch, a slow blow fuse on each
phase and an earth leakage circuit breaker.
• When using residual current operated circuit breakers, be sure to use a high-speed type (0.1 second or less)
30 mA rated residual operating current.

Communication wiring
• 2-core with non-polarity wire is used for wiring of the communication wiring.
• Wire size : AWG 14 to 20
• Up to 984 ft (300 m) (L1 + L2 + L3 )
NOTE
• Use copper supply wire.
• Use UL wire rated 600 V for the power supply.
• Use UL wire rated 300 V for the remote control wires and control wires.

Remote controller
The communication wiring and AC 208 - 230 V wires cannot be parallel to contact each other and cannot
be stored in the same conduits. If doing so, a trouble may be caused on the control system due to noise
or other factor.

CAUTION
„ 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. 3.9'' (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 upper side of the cover attachment screws (2 positions) of the electrical control
box, and remove the lower side of the screws (2 positions) to remove the cover.
2
Attach the conduit pipe with a lock nut.
3
The cable clamp (accessory) is installed in the underside of the Flow Selector unit.
4
Connect the power supply wire and communication wires to the terminal blocks of the
electrical control box.
5
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.)
6
Mount the cover of the electrical control box so that it does not pinch the wires.
