3.1 Piping procedure
zWhen there imay be pipe freezing, install a pipe warming device.
zTo prevent backpressure, make the exit-side pipes as short as possible. In addition, the
pipe exit must allow air to flow out freely, and must not be submerged in water. Do not
install the pipe vertically.
zBefore connecting the device, make sure to flush the sampling line.
Fig. 14 Piping
zRefer to the following table for diameters of the pipes and the pipe connectors.

Note
zThe diameters of the pipes shown in Table 3 match the diameters of connectors for OPSA-150. If
the water sampling point is distant from the device, use pipes with larger diameters than those
mentioned in Table 3.
zWhen piping the drain pipe, overflow pipes (1) and (2), and the discharge pipe, slope them
sufficiently so that the ends of the pipes can not be submerged in water.
zWhen using a flexible vinyl tube pipe, use a pressure-proof vinyl tube containing blade.
zRemovable piping is recommended so that the pipes can be disconnected for periodic cleaning.

4.1 Wiring procedure
4.1.1 Earth connection
zConnect the earth according to Type D earth connection procedures.
zBe sure to connect the earth bolt.
Fig. 15 Earth connection
Note
To prevent electric shocks, ensure correct earthing.
4.1.2 Power supply
Connect the power supply of the operation unit according to the signal table.
zUse a power cable of 1.25 mm2(AWG 16) or more in size.
zThe surge absorbers in the power terminal block are connected in parallel to prevent
noise. Tighten them together with the power cable.
zThe earth must be connected for safe operation.
zBe sure to connect the power terminals in the order of L phase, E (earth) phase and N
phase from the left. Ensure correct connection.

4.1.3 Cable connection for analysis unit
zPass the connector of the analysis unit through the cable clamp from the bottom left of the
operation unit.
zConnect the connector of the analysis unit to the connectors CN 1 and CN 2 located in the
bottom left of the inside of operation unit.
zAttach the round shield terminal to the screw hole under the connectors using a screw.

4.1.4 Float switch cable connection for overflow tank
zPass the float switch cable of the overflow tank through the cable clamp from the bottom
of the operation unit.
zConnect cables to the No. 7 and 8 terminals on the power terminal block in the center
bottom of the operation unit.
4.1.5 Signal line connection
zConnect the signal lines according to the external connection-wiring figure (V1039557A).
zUse a 2-pin shield cable for the current power output signal line and earth the shield at the
receiver side.
zConnect such devices as a surge absorber and noise killer in parallel to prevent noise in
contact output signals.
Note
zRefer to the separate OPSA-150 Operation Manual.
zDo not connect the power cable to the signal line wiring section. Doing so will cause
malfunctions.
zDo not turn the power on before introducing water to the system. The cell will rotate without
water, which can cause malfunctions.
