The standard Danish plug is described in DEMKO publication Afsnit 107-2-D1 and is unique to Denmark.
The Danish plug has a pin pattern similar to the standard Schuko CEE 7/7 plug, but grounding is achieved by use of a short ground pin. Although the standard Schuko CEE 7/7 plug fits the Danish socket, it will not be grounded, which may result in serious safety hazards and liability exposure for the manufacturer. For this reason, it is important to use a Danish plug on equipment being exported to Denmark. The cordsets have a maximum output rating of 10A/250VAC. All cordsets carry the appropriate approvals.
Data Circuits: A plug and socket standard has been developed for use in computer circuits that are especially sensitive to power line spikes and surges; Interpower’s cordset 86536060 utilizes the data plug. A mating power outlet (not stocked) accepts the data equipment plug, but not the standard Danish plug. See Data Circuits—Danish and British.
