General information
2.2 General product information
DANGER
Explosion hazard. The Hach GLI 3700 series sensors can only be
used with the si792(x) E transmitter.
2.2.1 Product overview
The si792 T, si792x T, si792 E and si792x E transmitters are used for
measurement of electrical conductivity and temperature in liquids.
Fields of application are: biotechnology, chemical industry,
environment, food processing and water/waste-water treatment.
The E and the T models differ only in the types of sensors that can be
used with the transmitter. The operation of each version is identical.
This user manual refers to both versions as E/T.
The molded transmitter enclosure can be attached to a panel, wall, post
or pipe railing. The optional hood (see Accessories on page 85)
provides protection against direct weather exposure and mechanical
damage.
Three communication options are available for the si792 transmitter:
• 4–20 mA/HART—si792 E, si792 T, si792x E and si792x T (noted as
si792(x) E/T)
• Foundation Fieldbus—si792x E-FF and si792x T-FF
• Profibus PA—si792x E-PA and si792x T-PA
This user manual includes instructions for all three protocols.
Important Note: An ‘x’ in the model number is an indication of an
intrinsically safe (IS) instrument.
The instruments are compatible with different sensor types. See si792
transmitter versions on page 85 for a list of instrument versions.
13
General information
2.2.2 FDA 21 CFR part 11 compliance (HART only)
In the directive “Title 21 Code of Federal Regulations, 21 CFR Part 11,
Electronic Records; Electronic Signatures“ the US American health
agency FDA (Food and Drug Administration) regulates the production
and processing of electronic documents for pharmaceutical
development and production. The features described in section 2.2.2.1
and section 2.2.2.2 make the transmitter compliant with the
requirements of FDA 21 CFR Part 11.
2.2.2.1 Electronic signatures for si792(x) E/T transmitters
Device functions are protected by passcode access, which prevents
unauthorized modification of device settings or manipulation of
measurement results. Passcodes may be used as electronic
signatures. Passcodes can be edited with the passcode editor
(Appendix C on page 105).
2.2.2.2 Audit trail for si792(x) E/T transmitters
The si792(x) transmitter can automatically track all changes to the
device settings. Each change is tagged with a Configuration Change
flag, which is documented using HART communication. Altered device
settings or parameters can be retrieved from the transmitter using
HART communication.
14
Section 3 Installation
DANGER
Explosion hazard. Trained personnel only must install or
commission the equipment.
DANGER
Explosion hazard. Never connect items to the transmitter that are
not specified on the control drawing. Do not connect or
disconnect any equipment unless power has been switched off or
the area is known to be non-hazardous.
DANGER
Explosion hazard. The safety of the transmitter may be impaired if
any of the following conditions have occurred:
• visible damage
• storage above 70 °C for prolonged periods
• exposure to severe transport stresses
• previous installation
• failure to operate properly
If any of these conditions have occurred, return the device to the
manufacturer for recertification.
The si792 and si792x transmitters differ in hazard classification. The
si792 transmitter is designed for non-hazardous or Class I, Division 2,
Groups A, B, C, D hazardous locations. The si792x transmitter is
designed for Class I, Division 1, Groups A, B, C, D hazardous locations.
Refer to the control drawing or listing applicable to the site location.
For outdoor installation, install a protective hood or sunshield
(see Accessories on page 85).
Installation of the si792x in an outdoor hazardous location per FM or
CSA control drawings requires a suitable enclosure and must follow
NEC guidelines. Refer to NEMA 250 to determine enclosure needs.
15
Installation
3.1 Hazardous location installation
Before installation, review the applicable Hazardous Location Control
Drawings or ATEX EC-Type Examination certificate and safety

3.4 Wiring Safety Information
When making any wiring connections to the instrument, the following
warnings and notes must be adhered to, as well as any warnings and
notes found throughout the individual installation sections. For more
safety information refer to section 2.1 on page 11.
DANGER
Always disconnect power to the instrument when making any
electrical connections.
Electrostatic Discharge (ESD) Considerations
To minimize hazards and ESD risks, maintenance procedures not
requiring power to the analyzer should be performed with power
removed.
Delicate internal electronic components can be damaged by static
electricity, resulting in degraded instrument performance or eventual
failure.
The manufacturer recommends taking the following steps to prevent
ESD damage to the instrument:
• Before touching any electronic components (such as printed circuit
cards and the components on them) discharge static electricity from
the body by touching an earth-grounded metal surface such as the
chassis of an instrument or a metal conduit or pipe.
• To reduce static build-up, avoid excessive movement. Transport
static-sensitive components in anti-static containers or packaging.
• To discharge static electricity from the body and keep it
discharged, wear a wrist strap connected by a wire to earth
ground.
• Handle all static-sensitive components in a static-safe area. If
possible, use anti-static floor pads and work bench pads.
20
Installation
3.5 Electrical installation
DANGER
Explosion hazard. Do not connect any components that are not
specified for the device. Always defer to the Hazardous Location
Control Drawing.
Prerequisites:
• Review the applicable control drawing or ATEX EC-Type
Examination certificate
• Review the electrical code regulations
• Review the regulations for electrical installations in hazardous
locations, if appropriate (e.g. EN 60079-10/EN60079-14;
94/9/EC directive; NEC; CEC; Profibus Technical Guidelines
2.091)
• Remove power or confirm non-hazardous status before making
any connections
• Confirm that the intrinsic safety of the device is maintained when
connected to other equipment such as a power supply unit.
3.5.1 Wire preparation
To remove the terminal blocks from the transmitter for sensor wiring:
1. Insert a flat screwdriver between the terminal block and the
transmitter body.
