Clamp
Never let the power cables of TB830D touch the
SENCOM cable for turbidity/chlorine (A), resulting in
failure to comply with the safety requirements.
• Open detector cover to wire.
• Wire SENCOM cable for turbidity/residual salt through the clamps in the figure. Never let the power cables of TB830D touch
the SENCOM cable for turbidity/chlorine (A), resulting in failure to comply with the safety requirements.
• A cable gland is attached to the wiring port. Securely tighten the wires so that they meet the IP65 or higher.
• After wiring is complete, securely tighten the four screws on the detector cover. The tightening torque of the screw is 1.5 N·m.
Figure 2.9 TB830D WIRING
WARNING
Wire power supply cable (TB830D power supply cable (C) or power supply cable (E)) in Figure
2.5 so that it does not come into contact with the SENCOM cable. Otherwise, it results in failure
to comply with the safety requirements.
