Failure to comply with the warning may result in very high risk for exposed personnel. This symbol indicates an important instruction. The SR ZERO A is a safety relays expansion used to connect the machine safety circuit to 2 OSSD output devices i.e.: · photoelectric light curtain · laser scanner · RFID sensor See details below about light curtain models, wiring, etc. When deciding on the safety category to be adopted, carefully consider the risks analysis of the machine. The module has been designed in particular for the ReeR light curtains of the Admiral AX (category 4), Vision VX and Vision VXL/MXL (category 2) series, EOS, Magnus RFID sensor and ReeR laser scanner. Consult ReeR before using the interface with other light curtain models or safety devices. For safe use of the device, it is essential to read and understand the contents of this handbook. Failure to comply with the prescriptions indicated in this notice may result in very high risks for the operating personnel of the protected machine. Englis h 8541408 - 17/05/2021 Rev.0 3 SAFETY RELAY SR ZERO A INSTALLATION AND ELECTRICAL CONNECTIONS SR ZERO A is provided with terminal blocks for the electrical connections. The unit provides 16 terminals. Terminal tightening torque: 5...7lb-in (0,6...0,7 Nm). Install SR ZERO A in an enclosure with a protection class of at least IP54. Connect the safety relay module when it is not powered. The supply voltage to the units must be 24 20% VDC; PELV (in compliance with the standard EN 60204-1 (Chapter 6.4)). Do not use the SR ZERO A to supply external devices. The same ground connection (0VDC) must be used for all system components. Figure 1 INSTRUCTIONS CONCERNING CONNECTION CABLES. Wire size range: AWG 12...30, (solid/stranded) (UL). Use 60/75°C copper (Cu) conductor only. We recommend the use of separate power supplies for the safety relay and for other electrical power equipment (electric motors, inverters, frequency converters) or other sources of disturbance. Cables used for connections longer than 50m must have a cross-section of at least 1mm2 (AWG16). The path of the connection cables between the safety relay and the sensors, the connection referring to the feedback contact must be different from that of other power cables.

These relays are rated by the manufacturer for voltage and current values above those indicated in the technical data; however, to assure correct insulation and to avoid damage or premature aging, protect each output line with an appropriate fuse (depending on the load). Check that load characteristics comply with the indications given in the table below.
