Verify use by checking the label on the Inline terminal and the packaging. WARNING: Explosion hazard The following conditions must be observed to adhere to the ATEX 94/9/EC directive. 8.1 Special conditions for safe use The module shall only be supplied from the IB IL EX-IS PWR IN-PAC module. If the module is installed in a zone 2 hazardous area, it shall be housed in an enclosure that is coded Ex nA, Ex e, Ex d or Ex p. If the module is installed in a zone 22 or 21 hazardous area, it shall be housed in an enclosure that is coded Ex tD or Ex t. For some types of enclosure, additional certification is required to permit the installation of the module within the enclosure. Reference should be made to the enclosure certificate. The installer shall ensure that the maximum ambient temperature of the module, when installed, is not exceeded. If the module is installed in a non-hazardous area, the enclosure or location shall provide suitable protection. This may be either by the use of an enclosure approved for use in zones 1, 2, 21, or 22 or otherwise meet the following requirements: – Non-metallic enclosures must be capable of withstanding the thermal endurance requirements of IEC 60079-0 prior to impact and IP54 testing. – Any enclosure must be capable of withstanding an impact of 7J or the module is otherwise protected from impact. – The enclosure or location must provide an ingress protection of at least IP54. – If exposed to sunlight, non-metallic enclosures must be capable of meeting the requirements of IEC 60079-0 clause 26.10 regarding resistance to light. The installer is responsible for ensuring that the mounting of the module does not reduce the segregation distances between different modules. There shall be a minimum of 6 mm between any intrinsically safe terminals and other conductors or earthed metal, in accordance with IEC 6007914:2007 clause 12.2.3. In addition, there shall be a minimum of 50 mm between the intrinsically safe terminals of the module and any non-intrinsically safe terminals. 2846_en_D When the module is mounted in a zoned area, live connection and disconnection of the module from the rail is only permitted if the potentially explosive atmosphere is shown to be absent. Each of the four channels of the IB IL EX-IS DIO 4/ NAM-PAC (4x digital in or 4x digital out) shall be treated as separate, intrinsically safe circuits. The IB IL EX-IS DIO 4/NAM-PAC input and output circuits may not be connected to the same equipment unless the equipment maintains isolation between the circuits. Each channel shares a common zero volts with the other channels in the IB IL EX-IS DIO 4/NAM-PAC module as well as other IB IL EX-IS DIO 4/NAM-PAC modules and non-isolated IB IL EX-IS…IO… modules connected to the same IB IL EX-IS PWR IN-PAC (power supply) module. If the field devices do not maintain 500 V AC isolation from earth/ ground, then all the non-isolated devices from the same IB IL EX-IS PWR IN-PAC module shall be installed in a location (such as the same vessel) where a difference in earth/ ground potential is unlikely to occur. If the field devices maintain 500 V AC isolation from earth/ground, there is no such limitation. The quoted entity parameters of Co and Lo are applicable for the distributed capacitance and inductance in cable. Where there is circuit capacitance or inductance in the connected equipment (represented by Ci and Lc respectively), these values shall not exceed 50% of the quoted Co and Lo. 8.2 Safety instructions WARNING: The safety instructions must be read and understood before installing and using this equipment. Installation instructions The device is an associated equipment of the “intrinsically safe” protection type and suitable for installation in zone 2. Follow the installation instructions. Installation, operation and maintenance may only be carried out by qualified personnel. Always remove power from Inline station before installing or removing any Inline terminal. Comply with the valid safety regulations (including national safety regulations) for the installation and operation, accident prevention regulations, and the general rules and regulations pertaining to technology. The safety relevant data may be derived from the operating instructions and the cer- PHOENIX CONTACT 7 IB IL EX-IS DIO 4/NAM-PAC tificates (EC type examination certificate, possibly additional ratings). WARNING: Substitution of components will impair intrinsic safety. 8.3 FM compliance In addition to the previous statements, FM compliance requires that the module is mounted in an enclosure that meets the requirements of ANSI/ISA 601010 and is installed according to the mounting, spacing and segregation requirements of the enclosure for the ultimate application. WARNING: To prevent ignition of flammable or combustible atmospheres, disconnect power before servicing. Access to the circuits or substitution of components within the device will impair intrinsic safety and is prohibited. Do not repair the device yourself, but replace it with an equivalent device. Repairs may only be carried out by the manufacturer. The IP20 degree of protection (IEC 60529/EN 60529) is intended for a clean and dry environment. Do not expose the device to any mechanical or thermal influences that exceed the limits described. Intrinsic safety 9 Installation instructions Always install the IB IL EX-IS... at the end of an Inline station. If additional power is required, a new node must be installed. Intrinsically safe wiring must be installed separately from non-intrinsically safe wiring (can’t be mixed within a wire channel). A new IS power supply is required if the red LED shows overloading. 9.1 Overview Inline intrinsically safe IO terminals can be installed in a standard Inline station and are supported by all major industrial networks. Basic and intrinsically safe wiring practices need to be followed by the following concept. When carrying out measurements on the intrinsically safe side, it is imperative that you observe the relevant regulations regarding connecting intrinsically safe electrical equipment. Only use equipment approved for intrinsically safe circuits. If the device was used in circuits that are not intrinsically safe, it is forbidden to use it again in intrinsically safe circuits. Label the device clearly as being not intrinsically safe. Installation in zone 2 Observe the specified conditions for use in potentially explosive areas! Use a suitable housing of the minimum protection IP54 for the installation. Within this context observe the requirements of IEC 60079-14/EN 60079-14, i.e., steel housing with a wall thickness of 3 mm. Do not connect any live cables/lines within the potentially explosive area. Only use IB IL EX-IS... modules of category 3G (ATEX 94/ 9EG). Potentially dust-explosive areas The device is not designed for use in environments capable of dust explosions. Only make the connection to the intrinsically safe circuit in potentially dust-explosive areas of zones 20, 21 and 22 if the equipment connected to this circuit is certified for this zone (e.g., category 1D, 2D or 3D). 2846_en_D PHOENIX CONTACT 8 IB IL EX-IS… IB IL EX-IS… IBSIL24BK-T/U IB IL EX-IS PWR-IN IB IL EX-IS DIO 4/NAM-PAC Local Bus OPC GND UL 7.5 V 5V 24 V 24 V 24 V 24 V US UEX OUT IN UM + Fieldbus Figure 4 - UBK Intrinsically safe Inline terminals power supply A new IB IL EX-IS PWR IN-PAC supply is required if the red LED on the power supply shows overloading. If additional power is required, a new node must be installed. 9.2 Power budget The IB IL EX-IS PWR IN-PAC provides power to the IB IL EX-IS DIO 4/NAM-PAC terminal in two ways: – 1000 mA is available for the logic functions (UL). – 1000 mA is available for the I/O functions (UEX). The number of terminals that can be powered by the IB IL EX-IS PWR IN-PAC varies according to the type of terminal and the number and type of I/O connections. Based on the logic functions, the maximum number of terminals that can be connected is 10. The IB IL EX-IS DIO 4/NAM-PAC terminal draws different power depending on the type of connection. To determine the number of I/O points that can be connected, refer to Table 1. 2846_en_D Table 1 UEX Current Draw Terminal overhead Output channel Input channel IB IL EX-IS DIO 4/NAM-PAC 20 mA 45 mA 10 mA To calculate the power requirements of a system, list the number and type of each connected point. From this list, determine the number and type of terminals required. Multiply the number of each I/O point by the appropriate current draw listed in Table 1. Add the terminal overhead current for each terminal used. The sum of the I/O point current draw and the terminal overhead current draw determines the total current draw from the IB IL EX-IS PWR IN-PAC. The maximum current draw is 1000 mA. Additional information and examples about power budget calculation can be found on the Power Supply data sheet.
