Hi,
I need your help on this. I am working on the emergency power system (battery back up system)of the dialysis machine. Our dialysis machine is class 1, when it is operated on the main power supply. I need to know when there is an interruption in the main power supply and machine is powered by emergency power system. Now the machine is still on class 1 or class 2? We don't have earth protection in emergency power system, so it means class 2 or is there any option to create that.
Class I
Equipment protection against electric shock by (Earthed) additional protection to basic insulation through means of connecting exposed conductive parts to the protective Earth in the fixed wiring of the installation.
Class II
Also referred to as Double Insulated. Equipment protection against electric shock by additional protection to basic insulation through means of supplementary insulation are provided, there being no provision for the connection of exposed metalwork of the equipment to a protective conductor and no reliance upon precautions to be taken in the fixed wiring of the installation.
regards,
Usman
