5 Safety regulations and installation notes
5.1 Installation notes
– The device must be installed in a housing. – The device is designed for installation in zone 2 poten- tially explosive areas. – Installation, operation, an d maintenance may only be carried out by qualified electricians. Follow the installa- tion instructions described. When installing and operat- ing 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 equiva- lent device. Repairs may only be carried out by the man- ufacturer. The manufacturer is not liable for damage resulting from violation. – The IP20 degree of protection (IEC 60529/EN 60529) of the device is intended for use in a clean and dry environ- ment. Do not subject the device to any load that ex- ceeds the described limits. – The device is not designed for use in atmospheres with a danger of dust explosions. – The housing of the device provides a basic insulation against the neighboring devices, for 300 V eff. If several devices are installed next to each other, this has to be taken into account, and additional insulation has to be installed if necessary. If the neighboring device is equipped with basic insulation, no additional insulation is necessary. – Provide overcurrent protection (I ≤ 16 A) within the in- stallation.
5.2 Installation in the Ex area (zone 2)
– Observe the specified conditions for use in potentially explosive areas. – Install the device into a housing (control or distributor box) that meets the requirements of EN 60079-0 and EN 60079-15 and at least IP54 (EN 60529) degree of protection. – During installation and when connecting the supply and signal circuits, observe the requirements of EN 60079- 14. 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 pow- er 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 de- vices from www.phoenixcontact.net/products. The "attention symbol" on the device label means: Follow the installation instructions to avoid im- pairing the intended protection!

6.4 Power supply
Power supply via the power terminals The power of the current transducer is supplied via the con- Power supply via DIN rail connector The current transducer MACX MCR-SL-CAC-5-I can addi- tionally provide power supply via the DIN rail connector ME 22,5 TBUS (Order No. 2707437). Supply via the MACX MCR-SL-CAC-5-I module In the event of a total current consumption up to 1 A by the modules in series, power can be supplied directly at the con- nection terminal blocks of the MACX MCR-SL-CAC-5-I- module. We recommend connecting a 1.25 A fuse upstream. NOTE: electrostatic discharge! The device contains components that can be damaged or destroyed by electrostatic dis- charge. When handling the device, observe the necessary safety precautions against electrostatic discharge (ESD) according to EN 61340-5-1 and EN 61340-5-1.

6.5 Assembly
Figure 3 Mounting and removing – 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 sup- ply. It is also absolutely vital that you snap the module and the DIN rail connector into position in the correct di- rection: the snap-on foot should be at the bottom and the connector on the left.
6.6 Connecting the wires
Insert the wires in the corresponding connection terminal block. Use a screwdriver to tighten the screw in the opening above the connection terminal block. Figure 4 Connection of the cables A B C A B
