7 Safety regulations and installation
7.1 Safety regulations for installation in the
potentially explosive area This Inline terminal conforms to standard EN 50021 and can be installed in a Zone 2 potentially explosive area. These Inline terminals are category 3 items of equipment. This Inline terminal for the indicated hardware version or later is suitable for use in Class I, Zone 2, Groups A, B, C, D. Installation in Zone 2 Observe the specified conditions for use in potentially explosive areas.
7.2 Installation and operation
Follow the installation instructions. When installing and operating the device, the applicable safety directives (including national safety directives), accident prevention regulations, as well as general technical regulations, must be observed.

8 Installation
8.1 Overview
Inline intrinsically safe IO terminals can be installed in a standard Inline station and is supported by all major industrial networks. Basic and intrinsically safe wiring practices need to be followed by the following concept. Figure 3 Intrinsically safe Inline terminals power supply The IB IL EX-IS PWR IN-PAC terminal: – provides isolation between unsafe power and power into the safe zone. – limits the available energy to the intrinsically safe I/O modules. – provides the required separation of 50 mm between safe and non-safe wire connections. Intrinsically safe wiring must be installed separately from non-intrinsically safe wiring (must not be mixed within a wire channel). Only one IS power supply can be installed in an Inline station. Onboard I/Os on a bus coupler may be used. If additional power is required, a new node must be installed.
8.2 Power budget
The IB IL EX-IS PWR IN-PAC provides power to the IB IL EX-IS…IO… terminals in two ways: – 1000 mA is available for the logic functions (U L). – 1000 mA is available for the I/O functions (U EX). The number of terminals that can be powered via the IB IL EX-IS PWR IN-PAC varies according to the type of terminal and the number and type of I/O connections. 24 V 7.5 V OPC UEX Local Bus GND UL Fieldbus US UM IN OUT UBK 24 V 24 V 24 V 5 V IBSIL24BK-T/U IB IL EX-IS PWR-IN IB IL EX-IS… IB IL EX-IS… The IB IL EX-IS PWR IN-PAC contains no logic function and therefore, does not draw power for itself.
2825_en_C 7PHOENIX CONTACT GmbH & Co. KG • 32823 Blomberg • Germany www.phoenixcontact.com Based on the logic functions, the maximum number of terminals that can be connected is 10. To determine the number of I/O points that can be connected, refer to Table 1. 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 current draw from the IB IL EX-IS PWR IN-PAC. The maximum current draw is 1000 mA. Example: For the following point count: To connect this number of points, the following number of terminals are required (four channels per terminal). Add the total current draw for each terminal to determine the total terminal overhead. Add the subtotals together and the total current draw from U EX is 645 mA. This is less than 1000 mA and does not exceed the maximum UEX current draw. The total number of terminals is 7 (less than 10). Based on the these totals, this is a viable configuration.
8.3 Connections
The IB IL EX-IS PWR IN-PAC terminal must be installed along within an existing IB IL system. The IB IL EX-IS PWR IN-PAC separates the existing IB IL system from the intrinsically safe area by providing isolation to the local bus as well as the I/O terminals (UEX).
