everything is ready for activation of the UPS. There is also a stand-by operating mode when in
battery-powered operation, provided the timer has been activated.
6) Connect the item(s) of equipment to be powered to the outlets on the rear of the UPS using the cable
supplied or another cable of max. length 10 metres.
WARNING: do not connect equipment that absorbs more than 10A to the IEC 10A outlets. For
equipment items exceeding this level of absorption, use only the IEC 16A socket.
