3.1.3Potential Equalisation
The potential equalisation stud at the rear of the unit is used to equalise the ground potential of the AT-10 plus to that of all mains powered equipment in the vicinity. Use the hospital or building common ground. A yellow/green ground cable is supplied as an option (Article number 2. 310 005).
To avoid possible interference from the ergometer when carrying out an exercise test, it is recommended that both the AT-10 plus and the ergometer are connected to the same common ground.
! To prevent the possibility of leakage current when an external printer, external monitor, or ergo device is connected, always ensure that the mains lead (with earth grounding connection), and / or the potential equalisation, is attached to the AT-10 plus.
