Mount the cable gland in the cable inlet hole.
Put the nut in place, and screw it onto the main body sufficiently. At this time, loosen the cap so
that the cable is not twisted. After fixing the main body, tighten the cap to keep moisture out of the
equipment. However if the cap is screwed up too tight, the cable will be damaged.

After completing the cable connections, replace the box cover securely, thus preventing moisture
from getting into the case.
l Connecting Sensor Cable to pH Transmitter/Converter
To connect the sensor cable to the two-wire pH transmitter, proceed as follows:
(1)
Loosen the four screws that tighten the transmitter cover. Then remove the transmitter cover.
(2)
Connect the sensor cables to the relevant terminals of the transmitter/converter:
First, remove the nut from the cable gland. Insert the cable into the right opening for the wiring.
Then pass the cable through the nut, Connect the individual cable conductors to the relevant
terminals correctly by referring to the markings on the individual conductors.
(3)
Install the cable gland in the wiring hole as follows:
Pass the tip of the cable gland into the opening and completely tighten the gland with the nut
inside the case.
After tightening the gland, secure the cap properly to prevent moisture from getting into the case.
Caution: Do not overly tighten the cap. Otherwise, the cable may be damaged.

After completing the cable connections, replace the transmitter/converter cover securely, thus
preventing moisture from getting into the case.
For details, refer to the relevant user's manuals for pH transmitter/converter.

Installing the sensor
(1) Mount the liquid junction in the sensor body. Peel off the seal attached to the liquid junction
mounting hole in the sensor body. Screw the liquid junction gently two or three turns into the
hole.

The PH8EHP pH sensor comes with a KCl solution reserve tank and its mounting hardware
when specified. Attach the mounting hardware to the pipe (nominal diameter 50 mm).
When suffix code "-TT1" is specified, connect the KCl solution refilling tube of the sensor to the
general purpose reserve tank holding a 250 mL KCl solution. With the tube connected to the
sensor, remove the cap from the tank and screw the connector of the tube in securely.
When suffix code "-TT3" is specified, connect the KCl solution refilling tube of the sensor to the
Big-volume reserve tank holding a 500 mL KCl solution.
Attach the nut in the
direction shown here
(so that it engages
the detent groove).
