Functional description
The Docking Station is required for the electrical installation in any area with an
"increased safety" explosion protection rating.
● Instrument for increased safety (Ex e)
The instrument is extended by an increased safety terminal box (docking
station) that provides up to four 20 mm openings, which can be used for field
wiring or wiring of a remote sensor. The permissible cable diameter range is
7 to 12 mm.
The Docking Station can be pre-mounted, wired and sealed with the supplied
cover. Once the site is ready for commissioning, the instrument is then hooked
up to the Docking Station and taken into operation; avoiding that the instrument
is damaged during the construction phase.
The connection between the Docking Station and the main instrument is
realized via a ‘feedthrough’. Depending on the instrument selected, there are 3
types of feed-through.
– feedthrough 3 wires for power
– feedthrough 9 wires for power and relay
– feedthrough 14 wires for power, interface connections or relay and remote
sensor (not for Polytron
