Page 6: Commissioning
Hochiki Europe (UK) Ltd – HE-PSU(4.0) Installation Manual As this is a 24-Volt system, there will be two 12 volt batteries which need to be connected in series. This is done using the jumper link provided. To optimise the service life of the batteries, the battery charger output voltage varies with temperature. To enable optimum temperature compensation, the flying lead thermistor should be attached to one of the batteries. - Page 7 Hochiki Europe (UK) Ltd – HE-PSU(4.0) Installation Manual To do this the batteries should be disconnected and the output voltage measured with a calibrated digital voltmeter. The voltage should be within 0.2 volts of the indicated voltage on the voltage/temperature graph below.
