2. Wiring and Installation
For details, refer to the User’s Manual IM 12E01B30-02EN.
2.1 Installation Site
Select an installation site where
Ambient Operating temperature: -5 to +55 ºC
Storage Temperature: -30 to +70 ºC
Humidity: 10 to 90% RH at 40ºC (Non-condensing)
Power Supply Voltage
Ratings: 100 to 240 V AC
Acceptable range: 90 to 264 V AC

Install the TB830D Surface Scattering Light Turbidity Detector at a location that
● is free from rain water such as an indoor location or in a cabinet.
● has low vibration.
● has low corrosive gas.
● is low humidity.
● has low temperature variation and where the temperature is maintained at or as near to
room temperature as possible.
● allows for su󰀩cient maintenance space with easy maintenance access.
● allows for drainage.

IM 12E04B40-01EN 1st Edition : Mar. 08, 2023-00
2.2 Piping
Pipe the sample, drainage, and washing water. If a sampling system is supplied with the product,
connect the pipe to the sampling system. If the sampling system is not supplied, connect the pipe
to TB830D detector. For proper operation of the instrument, the sample requirements, such as
ow rate, have to be met.
Refer to the User's manual IM 12E04B40-02EN and connect the pipes properly so that the
sample conditions are satised.
2.3 Wiring
WARNING
When Standard "-AD" (General purpose for CSA) with conduit adapter "/C□" is specied, always
use a dedicated plate for wiring to comply with safety regulations.
When wiring TB830D, rst remove the detector unit cover, then attach the cable gland.
Refer to user’s manual IM 12E04B40-02EN for details.

CAUTION
Turn o󰀨 power supply to TB830D before wiring. Power rating must comply with TB830D
specications. Power voltage must match with the one indicated on the name plate.
WARNING
● You must install external power supply switch or circuit breaker for power supply.
● The external power supply switch or a circuit breaker must comply with a current rating of
5Aor IEC60947-1 or IEC60947-3
● Yokogawa recommend installing the external power supply switch, circuit breaker and
TB830D all in the same location.
● Install the external power supply switch or circuit breaker to the place where operators
access easily. To alert users, put a label on the external power switch.
● Fix securely onto constructions or walls all power lines including wire cables of power supply
by using stanchion, cable rack, conduit or vinyl band.
Unplugged cables are dangerous and may cause an electric shock.
CAUTION
When you open the front cover on the detector and Relay Box, make sure the screws are
completely out of the screw holes, and then open the front cover slowly in order not to damage
the threaded parts on the housing. If the threaded parts are damaged and the screws cannot be
tightened, the waterproof performance will deteriorate.

nWiring the power supply
The cable size of terminals is 0.13 to 2.5 mm2in cross-sectional area or AWG 26 to 14. Supplied
with product cable gland is for cables nished O.D. of 6.5 to 12.5 mm. Seal up all unused cable
inlets with the supplied cable glands and close-up plugs. Refer to IM 12E01B30-02EN for details.
WARNING
The minimum cross sectional area of the protective grounding wire should be 0.75 mm2. For
CSA safety standard (Standard: - AD), use cables with a cross section of 0.75 - 2.1 mm2.
nWiring of TB830D
WARNING
Never let the power cable touch SENCOM cable, resulting in failure to comply with safety
requirements.
WARNING
● Use wiring cables with heat resistance above 75°C, waterproof rating IP65 or higher.
● Tightening torque to the four screws of Smart Box cover is 1.5 N·m.
● For power supply, wire cables with a ammability rating of UL 2556 VW-1 or equivalent.
Refer to FLXA402T Installation and Wiring IM 12A01G01-02EN.

3. Operation
Before starting an operation, follow the next procedure. Refer to IM 12E04B40-02EN for details.
(1) Check piping and wiring are all correctly provided.
(2) Set up the desiccant.
(3) Run water and check that there is no water leakage.
(4) Turn on the power and set to Maintenance mode.
(5) Congure parameters on the converter and detector unit.
(6) Conrm the reading is stable. Perform Zero/Span calibration.
(7) Switch to a measurement mode. Start a regular measurement.
4. Maintenance
nPeriodic maintenance
When you must open the front cover and/or glands, make sure that the seals are clean and
correctly tted when the unit is re-assembled in order to maintain the housing’s weatherproof
integrity against water and water vapor.
Certain parts must be replaced periodically to maintain product performance.
Refer to the user’s manual IM 12E04B40-02EN for details.
CAUTION
Never use harsh chemicals or solvents. If the instrument does become heavily stained or
scratched, you may need to replace some parts. Consult Yokogawa.
Fuse
There is a circuit board mounted fuse protecting the instrument. If a fuse blows soon after the
change, contact Yokogawa.
