2.2.1 SENCOM cable for Turbidity/Chlorine (A)
Without sampling system (-NN,-A5). For (-A5), refer to “2.2.5 Without a sampling system and
with a Relay box for solenoid valve”.
Dedicated cables are included. Refer to Figure 2.6, Figure 2.9, and Figure 2.10 for wiring.
Refer to Section 2.6.1 of FLXA402T Installation Manual (IM12A01G01-02EN) for the wiring on

2.2.2 FLXA402T power supply cable (B)
Without sampling system (-NN,-A5). For (-A5), refer to “2.2.5 Without a sampling system and with
a Relay box for solenoid valve”.
Dedicated cables are included. Refer to Figure 2.6, Figure 2.9, and Figure 2.10 for wiring. The
lengths of the terminal processes at both ends are different. Connect the longer side (approx.
80 mm) to TB830D side and the shorter side (approx. 50 mm) to FLXA402T side. Cables have
no terminal names on them. Wire them by color. L:Black, N: White, G: Red. M3 The tightening
torque for screws (L and N) is 0.6 N·m, and that for M4 screws (G) is 1.4 N·m .
