3. INSTALLATION INSTRUCTIONS
3.1. Installation of USB "NORTH" and connection of cables to it should be carried out in accordance with the relevant regulatory and technical documentation. Before installation, the product is subject to an external examination, while it is necessary to pay attention to the integrity of the enclosure, the presence of all fasteners, the presence of explosion protection marking, as well as the compliance of the main data of the nameplate with the conditions in which the product will be used
3.2. Unscrew the cover fixing bolts, remove the cover.
3.3. Check the tightness of the cable glands and make sure the rubber seals are present.
3.4. Feed the cable through the cable gland. Fasten securely inside the cable gland. To ensure a tight seal, the cable gland O - ring must be tightly fastened. Free the insulated cable cores from the outer insulation and cut off the ends of the inner insulation to a length of 8..10 mm. Connect the cable conductors to the terminals of the terminal block. Put on the cover, tighten the fastening bolts.
3.5. Fasten CSS "NORTH" to the bearing surface with three screws through the holes in the base. Installation dimensions are shown in Fig. 1.
4. ENSURING EXPLOSION PROTECTION DURING OPERATION
4.1 Explosion protection is achieved by using special protective measures in the design of the connecting device provided for by GOST R 52350.11 - 2005, including the use of antistatic plastic as a body material with a surface resistance of no more than 109 Ohm / cm2 at a temperature of (23 ± 2) oC and relative humidity (50 ± 5)% , as well as limiting the input parameters to intrinsically safe values that meet the requirements of GOST R 52350.11 - 2005 (IEC 60079 - 11 - 2006) (see clause 3.2). Also, the fastening screw of the cover of the connecting device is sealed, preventing unauthorized access to the connected conductors.
5. PROVISION OF EXPLOSION PROTECTION DURING INSTALLATION.
5.1. Persons with the necessary qualifications, familiar with this passport and trained in safety must be allowed to work on the installation and maintenance of the connecting device.
5.2. Before proceeding with the installation of the connecting device, it is necessary to inspect it. In this case, it is necessary to check the explosion protection marking and make sure that the housing is intact.
5.3. All work must be performed with disconnected power supplies.
5.4. External intrinsically safe electrical circuits must be connected from devices with intrinsically safe output parameters that have a GOST R certificate of conformity, a certificate of explosion protection from the State Energy Supervision Authority of the Ministry of Energy of Russia, a permit from the State Technical Supervision Agency of the Russian Federation for use in hazardous areas where the formation of a gas mixture of category IIC is possible.
5.5.
