5 Installation
5.1 Mechanical installation/mounting
Prior to installation, visually inspect the Tankvision Gauge Link for any signs of damage.
Confirm that the type label shows the correct field bus interface for the intended application.
The Tankvision Gauge Link must only be installed in a “safe” area where there is no hazard
from the presence of potentially explosive or flammable atmospheres.
The Tankvision Gauge Link must be installed in a cabinet or similar enclosure which provides
protection against dust and water ingress. The location must also provide protection against
moisture or the formation of condensation.
Ensure that the temperatures likely to be encountered at the installation location lie within
the relevant minimum /maximum operating and storage temperature ratings of the
Tankvision Gauge Link.
The Tankvision Gauge Link should not be installed near to high voltage circuits or to cables
feeding motors or other high current loads, or near to contactors, variable frequency drives,
inverters or frequency converters or other switchgear / controlgear which may emit
significant electromagnetic interference.
A clear space of about 50 mm (1.97 in) above and below the Tankvision Gauge Link
enclosure should be allowed for ventilation. A gap of 10 mm (0.39 in) to either side of the
Tankvision Gauge Link will ease mounting and opening of the front cover of the enclosure.
GaugeLink_Dimensions
The enclosure of the Tankvision Gauge Link is intended to be mounted onto “top hat” DIN
rail, T35 to BS EN 60715 (or BS 5584 / EN 50022 / DIN 46277-3). The rail should be
mounted on a vertical surface, with the rail running horizontally, so that the Tankvision
Gauge Link connection plate / access cover is to the front and in a readily accessible location.
To attach the Tankvision Gauge Link to the mounting rail, first hook the enclosure over the
top of the rail, then turn downwards until the spring clip on the back of the enclosure latches
onto the lower edge of the mounting rail (fig. A below).
