Installation, operation, and maintenance may only be carried out by qualified electricians. Follow the installation instructions described. When installing and operating the device, the applicable regulations and safety directives (including national safety directives), as well as general technical regulations, must be observed. The technical data is provided in this package slip and on the certificates (conformity assessment, additional approvals where applicable). It is not permissible to open or modify the device. Do not repair the device yourself but replace it with an equivalent device. Repairs may only be carried out by the manufacturer. The manufacturer is not liable for damage resulting from violation. The IP20 degree of protection (EN 60529) of the device is intended for use in a clean and dry environment. Do not subject the device to any load that exceeds the described limits. The device is not designed for use in atmospheres with a danger of dust explosions. 101948_en_01 5.2 – – – – – – Installation in the Ex area (zone 2) Observe the specified conditions for use in potentially explosive areas. The device must be installed in a housing (control or distributor box) which meets the requirements of EN 6007915 and provides at least IP54 (EN 60529) degree of protection. During installation and when connecting the supply and signal circuits, observe the requirements of EN 6007914. Devices may only be connected to circuits in zone 2 if they are suitable for operation in Ex zone 2 and for the prevailing conditions at the place of use. In potentially explosive areas, terminals may only be snapped onto or off the DIN rail connector and wires may only be connected or disconnected when the power is switched off. The device must be stopped and immediately removed from the Ex area if it is damaged, has been subjected to an impermissible load, has been stored incorrectly, or if it malfunctions. You can download the latest documents for these devices from www.phoenixcontact.net/catalog.

The necessary power is supplied by a current loop on the input side, e.g. in the form of a transmitter (see the section titled "Connection/Application example"). S Figure 1 1. 2. 3. 4. 5. 6. 7. Structure However, MINI passive isolators can be snapped onto a DIN rail connector – no electrically conductive connection is established. This means that it is not necessary to disconnect an existing connection involving DIN rail connector elements.

Use a screwdriver to tighten the screw in the opening above the connection terminal block. Spring-cage connection: Mount the module on a 35 mm DIN rail according to EN 60715. When using the DIN rail connector, first place it into the DIN rail (see A – C). It is used to bridge the power supply. It is also absolutely vital that you snap the module and the DIN rail connector into position in the correct direction: the snap-on foot should be at the bottom and the connector on the left.
