1.1Description of construction of modular control units. Parts included.

Modular control units (MCU) is a precast construction, consisting of a housing with a lid (door), cable glands, internal components (terminals, tire-barrier, etc.) and external components such as buttons, switches, pilot lights. Housing (shell) of modular control units has the seal between cover and to provide ingress protection at least IP66.

Modular control units shown in the following series: MT, MB, MP, MC. The main element of MCU is the housing (several housings) with cover or hinged door, which in turn are fixed with screws. The housing mounted certified Ex components. On the sides of housings set certified cable glands, connection modules or other external built-in items. On the cover can be installed built-in certified elements.

The design of MCU series MT, MB, MP, MC determined by the project, which is developed for a specific design, based on the requirements of technical specifications TС (technical condition) 3431-001 - 15232514-07, GOST R 51330.0-99, GOST 51330.1-99, GOST R 51330.6 - 99, GOST 51330.8-99, GOST R 51330.10-99; 51330.17-99 GOST, IEC P 61241-1-1-99 and other regulatory documents.

Material of housing:• glass reinforced polyester• aluminum alloy with corrosion-resistant coating• stainless steel

1.1Serial range of MCU

Modular control unit shown in the following series:

• Terminal Module (МТ)- an enclosure within which the terminals are installed (and / orother Ex-components) or distribution busbars. On the sideperimeter of the shell are set cable glands, connection modulesor other external components. This series is used as a terminalbox for connections and distributions of the various circuits ofthe control systems, signaling and communications.

• Barrier Module (МВ)– this series is similar in design to the MT series, except toinstall in shell an intrinsically safe electrical equipment. Thisseries is used for connecting and switching intrinsically safecircuits.

• Protective Module (MP)– a housing, which contains various protection devices (Ex-components) - fuses. On the side perimeter of the shell are setcable glands, connection modules or other externalcomponents. This series is used for the protection of variouselectrical systems.

• Control Module (МС)- an enclosure within which the terminals are installed (and / orother Ex-components) or distribution busbars. On the sideperimeter of the shell are set cable glands, connection modulesor other external components. On the cover or hinged doorhousing (shell) installed certified for this purpose command,signal, display modules - push button latching and non-latching, rotary switches, potentiometers, emergency stopbuttons, pilot lights, etc. These elements can be mounted on thelid, or a hinged door, and on the support rails mounted insidethe shell.

Housing material of MCU

• Aluminum

Aluminum housing of MCU proved as junction boxes and control stations for placement of various electronic components. It produced by injection molding and has excellent anti-corrosive characteristics, including marine. These devices have high mechanical and thermal resistance, and that's why we can use it in harsh industrial environments. MCU has 58 standard size of shell which make possible to solve various tasks on the wiring cables, as well as challenges for the assembly of control devices according to customer specifications.

• PolyesterGRP (glass reinforced polyester) MCU has increased reliability.

Material has high resistance to oil, aromatic hydrocarbons,

bacteria and enzymes pollution; resistant to mechanical stress and has a long service life. Polyester antistatic and non-corrosive. This is achieved by use of polyester body material SMC, fiberglass reinforcement which is in the form of fortified sheets, not threads (DMC), which is used by most manufacturers. Using the SMC-polyester gives the greatest strength of the housing and, in the case of exposure to open flame, its structure does not lose strength and grip even in burning resin when exposed high temperatures.

• Stainless steel Stainless steels have high strength and resistance to aggressive

environments, including seawater. More than 60 dimensions used in the MCU housing of stainless steel, can offer different solutions for the problem. As the junction boxes are available with interchangeable plates for cable glands (gland plate). Simple and easy installation. A wide range of finished units, long life, excellent design.

Advantages of MCU

In our products we use components of famous manufacturers, tested and received the international and Russian certificates.

Housing products are made of high quality materials: polyester (МТР, МВР, МРР, МСР), aluminum alloy Al Si – 12 (МТА, МВА, МРА, МСА) and 316L stainless steel (МТС, МВС, МРС, МСС).

Cable glands used in MCU, have passed all necessary tests and received certification in Europe, America, Australia and Russia. Wide range cable entry allows connection in fact all types of cables - armored, unarmoured, in grid and lead sheath, installed in a pipe or metal hose. Arsenal cable entries allow us to provide a solution for cables with diameters from 3.1 mm to 130 mm. Sealing rings and locknuts are always installed, because the ring is reinforce protection the device from external influences, and locknuts is additionally reinforce the cable entry and provide a lead in the ground circuit with a copper plate continuity. These options are always install.

In all MCU series terminal blocks are used only famous manufacturers. Information on applicable standard terminal blocks provided in Appendix 3.3.3. If you have special requirements in terms of terminals manufacturer, we will design your unit with the use of this terminals, provided they all permits for use in hazardous areas. Terminals are mounted on a standard rail.

If necessary, installed mounting plate to set terminals or other components inside boxes .

Neoprene or silicone seal housing cover is used in MCU, depending on the temperature range in which to operate the unit.

As an grounding we can use internal / external ground rod, internal plate grounding continuity (copper), special ground terminals, which situated on the terminal rod or own internal ground bus installed separately. Grounding negotiated at order.

External hinges are used in the production of electrical cupboards and control modules and signaling. If brackets are mounted on the frame, or other structure that requires additional steps to install and operate the unit, external mounting brackets supplied with the unit.

Condensate drain device, used in MCU, combines two functions: condensate drainage and ventilation devices. It is installed in the bottom of the unit and eliminates the accumulation of liquid inside the housing with season and manufacturing temperature changes.

Nameplate placed on the lid of the unit and may contain the information necessary to your electrical system, control or alarm. This information may be specified when ordering.

All the options included in the unit when it designing. We offer a timely solution to the day of the order. In addition, in the catalog you can find ready-made solutions junction boxes and control stations that will help you in solving engineering problems.
