The customer is asking to have installed additional clear polycarbonate screens to the UPS PDU cabinet. These are required to
prevent people touching the exposed AC and DC electrical connections.
According with Electrical Safety protection in United Kingdom , space in the back of the PDU ,where the UPS5000 is located need to be installed and designed a bigger clear polycarbonate screen.
