5 Safety regulations and installation
5.1 Installation and operation
- The category 3 device is suitable for installation in po- tentially explosive area zone 2. It fulfills the require- ments of EN 60079-0:2012 and EN 60079-15:2010.
- Installation, operation, and maintenance may only be carried out by qualified electricians. Follow the installa- tion instructions as described. When installing and op- erating the device, the applicable regulations and safety directives (including national safety directives), as well as general technical regulations, must be observed. For the safety technology data, see this packing slip and the certificates (EC examination certificate and other ap- provals if appropriate).
- With the exception of configuration of the thumb wheel, opening or modifying the device is not permitted. Do not repair the device yourself; replace it with an equivalent device. Repairs may only be performed by the manu- facturer. The manufacturer is not liable for harm result- ing from noncompliance.
- The IP20 protection (IEC 60529/EN 60529) of the de- vice is intended for use in a clean and dry environment. The device must not be subject to mechanical strain and/or thermal loads, which exceed the limits de- scribed.
- To protect the device against mechanical or electrical damage, install it in a suitable housing with appropriate degree of protection as per IEC 60529.
- The device is not designed for use in atmospheres with a danger of dust explosions.
- If dust is present, it is necessary to install into a suitable approved housing, whereby the surface temperature of the housing must be taken into consideration. WARNING: Risk of electric shock – Provide a switch/circuit breaker close to the device, which is labeled as the dis- connect device for this device or the en- tire control cabinet. – Provide overcurrent protection (I ≤ 6 A) in the installation. – Disconnect the device from all power sources during maintenance work and configuration (the device can remain con- nected to SELV or PELV circuits). – The housing of the device provides a ba- sic insulation against the neighboring de- vices, for 300 V eff. If several devices are installed next to each other, this has to be taken into account, and additional insula- tion has to be installed if necessary. If the neighboring device is equipped with ba- sic insulation, no additional insulation is necessary. CAUTION: Observe the following safety notes when us- ing the device.

6.3 I/O MAP address in the Radioline wireless
Use the thumbwheel to set the I/O-MAP address. The exten- sion module in the Radioline wireless system is addressed using the I/O-MAP address. On the entire wireless network, addresses 1 to 99 (I/O MAP) (maximum) may be assigned for the I/O extension modules.
6.4 Network applications (operating mode)
You can set the network application of the wireless module with the PSI-CONF software. All RAD-2400-IFS Radioline wireless modules are set to I/O data mode (wire in/wire out) by default. Radioline wireless module in I/O data mode The input device must be provided with the same I/O MAP address as the assigned output device at the other Radio- line wireless station (I/O mapping). Only the RAD-AO4-IFS module can be assigned to the RAD-PT100-4-IFS module. The Pt 100 inputs, T1 ... T4, can be configured to the analog outputs I1/U1 ... I4/U4 of the RAD-AO4-IFS extension mod- ule. Radioline wireless module in PLC/Modbus RTU mode The I/O MAP address of an input module may only appear once in the network. The input data is saved in a Modbus memory map in the Radioline master wireless module. You can read or write the process data via the serial inter- face of the RAD-2400-IFS master wireless module (RAD-ID = 01) using the Modbus RTU command (see Section 7). The I/O MAP address of an input module may only appear once in the network. Thumb wheel settings

6.6 Temperature input (Pt 100)
The Pt 100 inputs of the extension module can process tem- peratures from -50 °C ... +250 °C. All the inputs are electrically isolated from one another, from the supply voltage (via bus foot), and from other electronic components. Pt 100 resistance thermometers can be connected to the RAD-PT100-4-IFS I/O extension module. The thermome- ters change their resistance depending on the temperature. The Pt 100 input signals are acquired by the RAD-PT100-4- IFS and can be mapped to proportional, analog voltage or current signals of the RAD-AO4-IFS output module. Thus, conclusions can be made about the temperature via the standard analog signal. 1 °C 66.66 μA Figure 5 Current strength [mA] depending on the tem- perature [°C] PWR LED The green PWR LED indicates the supply voltage status.

6.7 Assembly/removal
Figure 6 Mounting and removing When using the device in a connection station, use the 17.5 mm wide DIN rail connector supplied. Only use the DIN rail connector in connection with 24 V DC devices.
- Connect the DIN rail connectors together for a connec- tion station.
- Push the connected DIN rail connectors into the DIN rail.
- Place the device onto the DIN rail from above. Ensure the device and DIN rail connector are aligned correctly.
- Holding the device by the housing cover, carefully push the device towards the mounting surface so that the de- vice bus connector is securely fixed onto the DIN rail connector.
- Once the snap-on foot has been audibly snapped onto the DIN rail, check that it is fixed securely. The device is only mechanically secured via the DIN rail.
- Connect the desired number of I/O extension modules to the wireless module via the DIN rail connector.
- Install the device in suitable housing to meet the re- quirements for the protection class.
- During startup, check that the device is operating, wired, and marked correctly.
- You can establish a connection between two DIN rail connectors using MINI COMBICON connectors: MC 1,5/5-ST-3,81 (female, 1803604); IMC 1,5/5-ST-3,81 (male, 1857919).

6.9 Connecting the sensors
You can connect 2-wire or 3-wire sensors to the extension module. Take into account the measuring errors depending on the different measuring methods. 2-wire connection method With 2-wire technology, you need an insertion bridge be- tween terminals x.2 and x.3. For short distances (< 10 m).
- Connect the Pt 100 sensor to terminals x.1 and x.3.
- Bridge the terminals x.2 and x.3. 2-wire connection technology is the most cost-effective con- nection method. The temperature-related voltage is not di- rectly measured at the sensor and is therefore falsified by the two cable resistances. The measuring errors that occur may render the entire measurement useless. Figure 8 2-wire connection technology Cable resistances R L1 and RL2 are incorpo- rated in the measurement result directly and falsify the result accordingly. µC2.1 2.2 2.3 3.1 3.2 3.3 5.1 5.2 5.3 4.1 4.2 4.3 IO-MAP 0 1 DC DC IFS IFS A D 1mA A D 1mA A D 1mA A D 1mA -I2 -U2 +I2 +I1 -U1 -I1 +I3 -U3 -I3 +I4 -U4 -I4 RL RL RTD ϑ
105366_en_00 PHOENIX CONTACT 13 3-wire connection method For long distances between the Pt 100 sensor and the ex- tension module. To compensate the wire resistances, all wire resistances must have exactly the same values (RL1 = RL2 = RL3).
- Connect the Pt 100 sensor to terminals x.1, x.2, and x.3. With 3-wire connection technology, the temperature-related voltage is measured several times. Corresponding calcula- tions additionally reduce the effect of the cable resistance on the measurement result. The results are almost as good as those achieved using 4-wire technology. The cable resistances RL at terminals +I and -I must have the same value. This allows you to subtract the established cable resistance from the measurement result and to get the Pt 100 platinum resistance value.

- If you want to use a 4-wire sensor, only connect three of the four wires.
- The fourth wire should be left unwired. Otherwise there will be a different resistance in the +I and -I cables owing to the parallel connection of two cable resistances.
