TECHNICAL SPECIFICATION
ELECTRICAL, AUTOMATION AND INSTRUMENTATION SYSTEM -SPECIFICATION AND INSTALLATION GUIDELINE  VS1
16.1.5 The conventional cable trays composing the instrumentation circuits may not be shared with
other cable types and the routes must be determined in order to avoid high-temperature or
risky zones
16.1.6 The network cables must be protected by metallic conduits and may be installed on the
outer sides of the instrumentation trays.
16.1.7 The temperature sensors must be directly connected to the PLC cards.
16.1.8 When specifying the instrumentation elements it must be considered that VSB may decide
to use nitrogen instead of compressed air.
16.1.9 The transmitters must preferably be installed near the impulse sockets in order to avoid
measurement retards and they should be the most possible grouped. They may not be
affected by vibrations and temperature of nearby equipment.
When necessary they must be assembled in cabinets for protection against mechanical shocks.
16.2 Pots, drain valves, isolating valves, sealing liquid, seals with diaphragms, flow switches,
pressure switches, etc. must be supplied wherever necessary.
16.3 Stainless steel pipes, in principle with diameter 16 mm shall be used for the piping of
impulse sockets. The sockets must be mounted in such a manner that is becomes possible
to pass a rod through them for cleaning and removing obstructions.
16.4 Ermeto type connections must always be used in instrumentation piping.
16.5 A minimum slope of 1/20 must be foreseen in order to avoid accumulation of impurities and
humidity in the inside of the piping.
16.6 All instrumentation elements must be provided with access facility by means of walkways or
platforms for ensuring efficient and safe maintenance.
16.7 The minimum protection class of cabinets and boxes for instruments installed externally
must be IP-54 and they must dispose of complementary cover with frontal advance for
protection against rain.
16.8 The panels for installation of instruments must be built of steel sheets at least 2.65 mm thick
for the structure and have assembly plates, doors and covers. The covers and the doors
must be provided with sealing for preventing dust entry and the hinges must be installed on

be taken to the control equipment:

? When using double conductors, these must be shielded;
? When using multi-conductor cables, each one must have separate full shielding for each
pair;
? The extension cables must also be provided with shielding;
? Cables of three or four twisted and shielded conductors must be used for connection of
resistance bulbs;
? The norm DIN 437 10-4 must be adopted for the colors of compensation cables.

16.14 All installation, maintenance, configuration, programming, etc. manuals must be supplied for
all elements of instrumentation systems.
16.15 The process flowcharts and the P&l, with details of all piping and fluids for the instruments

17 ELECTRICAL AND CONTROL ROOMS
Localization, layout, panel arrangements, furniture, etc. and all and any matter related to rooms belonging to the electrical and control systems, must be previously discussed with the VSB team in order to standardize and optimize designs A priori these rooms must have at least three doors. One for moving materials and equipment and the other two, installed on opposite sides, for circulation of the personnel. These doors must have "quick exit" type locks for facilitating emergency evacuation. These rooms must be air-conditioned when necessary or at least have forced ventilation through filters. There must be separate rooms for medium voltage, batteries and low voltage. The free height of the electrical system rooms may never be less than 2.5 meters.
