To take leaks into account, the value obtained should be increased by10%.The table shows an example of a flow rate with (t a - t e )=5°C and a rated resistive load (pf=0.9).(Note: This formula is applicable if ta>te, only; if not the UPS installation requires an air-conditioning system).*** The leakage current of the load is to be added to that of the UPS on the earth wire.
