Bul. 937C HART Loop Converter Installation Instructions
The HART Loop Converter must only be operated by trained personnel in
accordance with this handbook.
The protection of operating personnel and of the system is only ensured if the devices
are used in accordance with their intended purpose. Any other type of operation than
that described in this manual places the safety and functionality of the devices and
systems connected to them in question.
The devices may only be installed, connected, and adjusted by electrical professionals
outside the hazardous area.
If faults cannot be elimina ted, the devices must b e taken out of operation and protected
from being placed in service again inadvertently. Tampering with or making changes to
the devices is dangerous and therefore not permitted. They render the warranty void.
The responsibility for the adherence to local safety standards lies with the operator.

Reference to further documentation
Laws, standards, or directives applicable to the intended use must be observed. In
relation to hazardous areas, Directive 1999/92/EC must be observed.
The corresponding data sheets, declarations of conformity, EC-type-examination
certificates, certificates and Control Drawings if applicable (see data sheet) are
an integral part of this document. You can find this information under
www.ab.com.
Due to constant revisions, documentation is subject to permanent change. Please refer

Intended Use
The devices are only approved for appropriate and intended use. Ignoring these
instructions will void any warranty and absolve the manufacturer from any liability.
The device must only be operated in the ambient temperature range and at
the relative humidity (non-condensing) specified.
The de
vices are used in Control &Instrumentation (C&I) technology for the galvanic isolation
of C&I signals such as 20 mA and 10 V standard signals or alternatively for adapting or
standardizing signals. Devices that incorporate intrinsically safe circuit are used for
operating intrinsically safe field devices in hazardous areas.

The device must not be installed at locations where corrosive vapors may be present. The
devices fulfill a degree of protection IP 20 according to IEC/EN 60529.
The devices are designed for use in pollution degree 2 and overvoltage category II as per
IEC/EN 60664-1.
If used in areas with higher pollution degree, the devices need to be protected accordingly.
Only use power supplies that provide protection against direct contact (e. g. SELV or
PELV) for the connection to power feed modules.
Observe the tightening torque of the terminal screws.
The installation instructions in accordance with IEC/EN 60079-14 must be observed.
Intrinsically safe circuits of associated apparatus (installed in safe areas) can be led into
hazardous areas, whereby special attention must be paid to maintain separation distances
to all non-intrinsically safe circuits according to the requirements in IEC/EN 60079-14.
All separation distances between two adjacent intrinsically safe circuits need to be
observed in accordance with IEC/EN 60079-14.
If "Ex i" protected circuits (intrinsically safe) were operated with non-intrinsically safe
circuits, they must no longer be used as "Ex i" protected circuits.

DIN Mounting Rail
The devices are mounted on a 35 mm DIN mounting rail according to EN 60715.
Example: DIN mounting rail(35 mm x 15 mm)
Power Rail
To reduce wiring and installation costs, Power Rail is the optimum solution. The
Rail is a DIN mounting rail with plastic insert, that delivers power to the devices (24 V
DC) and transfers bus signals and a collective error message.
The Power Rail is factory-equipped with cover
and open segments of the Power Rail. Thus, the Power Rail is protected from
contamination. Additionally the cover and end caps prevent that electrically conductive
parts come in contact with the Power Rail.
