Protection class PN-EN 60950-1:2004 I (first) Protection grade PN-EN 60529: 2002 (U) IP20 Electrical strength of insulation: - between input (network) circuit and output circuits of power-supply (I/P- 3000 V/AC min. O/P) - between input circuit and PE protection circuit (I/P-FG) 1500 V/AC min.
- TAMPER signalization of power-supply unit opening 6. Set appropriate battery charging current - jumper ‘J1’ (refer to table 1 and figure 2). 7. Using the dip switch ‘JP-B’ determine whether the function of disconnecting the discharged battery U<10V (+/- 5%) is to be on or off.
4. Handling and operation. 4.1 Overloads or short circuits to the PSU. The AUX output of the PSU is equipped with the PTC polymer fuse assisted protection. If the load of the exceeds I (load 110% ÷ 150% @25ºC of the PSU power), the output voltage is automatically disconnected and this is indicated by the green diode going off.
