Temperature Resistance For The Connecting Cables; Cable Entries - ABB VortexMaster FSV430 Commissioning And Safety Instruction

2.2.3

Temperature resistance for the connecting cables

The temperature at the cable entries of the device is
dependent on the measuring medium temperature T
and the ambient temperature T
For electrical connection of the device, cables suitable for
temperatures up to 110 °C (230 °F) can be used without
restriction.
Use in category 2 / 3G
For cables suitable only for temperatures up to 80 °C (176 °F),
the connection of both circuits must be checked in the event
of a fault. Otherwise, the restricted temperature ranges listed
in the following table shall apply.
Use in category 2D
For cables suitable only for temperatures up to 80 °C (176 °F),
the restricted temperature ranges listed in the following table
shall apply.

Cable entries

NOTICE
Devices with a 1/2" NPT thread are supplied without cable
glands.
The devices are supplied with cable glands certified according
to ATEX or IECEx.
The cable glands supplied are approved for use in Zone 1.
Please observe the following points:
— The use of standard cable glands and seals is prohibited.
— The black plugs in the cable glands are intended to
provide protection during transport. Any unused cable
entries must be sealed securely before commissioning.
— The outside diameter of the connection cable must
measure between 6 mm (0.24 inch) and 12 mm (0.47 inch)
to ensure the necessary seal integrity.
Use of the devices in Zone 0 / 20
If the devices are used in Zone 0 / 20, the cable glands
supplied must be replaced with cable glands approved for use
in Zone 0.
Flame-resistant pipe fittings
The electrical connection for the flowmeter is made via the
cable gland on the device. Alternatively, the flowmeter can be
connected using an approved flame-resistant pipe fitting
located directly on the device.
To do this, the existing cable gland must be removed.
When selecting suitable flame-resistant pipe fittings, please
note the following:
— The requirements set out in EN 50018 section 13.1 and
13.2 must be observed.
— The installation requirements set out in EN 60079-14 must
be complied with when selecting pipe fittings.
— The outside diameter of the unshielded connection cable
must be between 8.0 mm (0.31") and 11.7 mm (0.46").
NOTICE
The flame-resistant pipe fitting must be assembled in
accordance with the manufacturer's assembly instructions
supplied with the pipe fitting.
