2)
2.4 Intended operating area and operating
conditions
Hazardous areas classified by zones:
The device is only designed for use in Zone 1 or Zone 2
potentially explosive atmospheres for which a temperature
range as specified on the device must be observed and in which
gases of Explosion Groups IIA, IIB or IIC and Temperature
Classes T4 or T6 (depending on maximum ambient
temperature) or dust of Groups IIIA, IIIB or IIIC may occur.
Hazardous areas classified by divisions:
The device is only designed for use in potentially explosive
atmospheres of Classes I&II, Div. 1 or 2, for which
a temperature range as specified on the device must be
observed and in which gases or dust of Groups A, B, C, D or
E, F, G and Temperature Classes T4 or T6 (depending on
maximum ambient temperature) may occur.
2.5 Approvals
See printed version for approval markings.
2.6 Device marking
The device marking is supplied with the device as a copy on
a separate document.
Key to the Serial Number: The third letter of the Serial Number
specifies the year of manufacture: A = 2009, B = 2010, C = 2011,
D = 2012, E = 2013, F = 2014, H = 2015, J = 2016, K = 2017 etc.
Example: Serial Number ARBH-0054: The third letter is B,
i.e. the device was manufactured in 2010.
3 Installation
3.1 General information for the installation
The selection of a suitable mounting location is crucial for
the effectiveness and performance of the entire system. Every
detail of the installation must be thoroughly thought out.
The following must be noted in particular:
z
the local and national rules and regulations for the
installation of gas monitoring systems,
z
the applicable regulations for running and connecting
power and signal cables to gas monitoring systems,
z
the full extent of environmental influences to which the
device will be subjected,
z
the physical properties of the gases and vapors to be
measured,
z
the details of the particular application (e.g., potential
leaks, air movements/flows, etc.),
z
accessibility for required maintenance activities,
z
the geometric of the accessories that are used with the
system,
z
all other limiting factors and stipulations that may affect the
installation of the system.
z
For installation without a conduit, an approved cable gland
(e.g. Hawke A501/421/A/¾" NPT or equivalent) must be
used (see chapter 12 on page 28). To increase the RF
interference immunity, it may be necessary to connect the
cable screen to the cable gland and to the control unit.
z
The explosion proof enclosure has three ¾" NPT
connections, which can be used for field wiring, the direct
attachment of a sensor or wiring an external sensor.
Unused openings must be closed off with a plug. For the
correct tightening torques for cable bushings, plugs,
sensors and connectors, see chapter 12 on page 28.
z
The secondary are supposed to be supplied from an
isolating source (does not apply to relay contacts).
z
The optional e-Box has up to four 20 mm connections,
which can be used for field wiring or wiring an external
sensor. The permissible cable diameter is 7 to 12 mm.
z
If the device is installed in locations where ambient
temperatures of over 55 °C prevail, appropriate cables
which are specified for use at temperatures of 25 °C above
the maximum ambient temperature must be used.
z
Strip back the insulation on conductors by 5 to 7 mm.
z
Connect the cable as shown in Chapter 3.5 on page 9
(shown here also with protective ground) oder Chapter 3.6
on page 10.
z
The connecting wires for the optional relay module must be
selected and fused according to the rated voltages,
currents and environmental conditions.
z
When stranded conductors are used, an end ferrule must
also be used.
WARNING
Explosive. Not to be used in oxygen enriched
atmospheres. None of the Polytron 8000 transmitters
is certified and approved to be operated in oxygen
enriched atmospheres.
