2 Intended Use <strong>HIMax</strong>2.3.4 Power SupplyThe following table lists the key tests and limit values for the device's power supply:IEC/EN 61131-2Table 8:Review of the DC supply characteristicsAlternatively, the power supply must <strong>com</strong>ply with the followingstandards:IEC/EN 61131-2 orSELV (<strong>Safety</strong> Extra Low Voltage) orPELV (Protective Extra Low Voltage)<strong>HIMax</strong> devices must be fuse protected as specified in this manualVoltage range test:24 VDC, -20 %...+25 % (19.2 V...30.0 V)Momentary external current interruption immunity test:DC, PS 2: 10 msReversal of DC power supply polarity test:Refer to corresponding chapter of the system manual or data sheet ofpower supply.Backup duration withstand test:Test B, 1000 hReview of the DC Supply Characteristics2.3.5 ESD Protective MeasuresOnly personnel with knowledge of ESD protective measures may modify or extend thesystem or replace a module.NOTEElectrostatic discharge can damage the electronic <strong>com</strong>ponents within thecontrollers!• Touch a grounded object to discharge any static in your body.• When performing the work, make sure that the working area is free of static andwear an ESD wrist strap.• If not used, ensure that the module is protected from electrostatic discharge, e.g.,by storing it in its packaging.Only personnel with knowledge of ESD protective measures may modify or extendthe system wiring.2.4 Requirements to be met by Machine and System ManufacturersThe machine and system manufacturers are responsible for ensuring the safe application of<strong>HIMax</strong> systems in automation systems and overall plants.The correct programming of the <strong>HIMax</strong> systems must be sufficiently validated by themachine and system manufacturers.Page 14 of 70HI 801 003 D Rev.2.0
