Abstract

The device for use in an explosive atmosphere zone has a device housing and at least one energy supply part that is provided with at least one battery or at least one rechargeable battery as well as energy-associated supply contacts. The energy-associated supply contacts interact with device-associated supply contacts when the energy supply part is connected to the device. The energy-associated and device-associated supply contacts have connected upstream thereof switches that, prior to separation of the energy supply part from the device, can be controlled by a circuit such that the switches deenergize the energy-associated and the device-associated supply contacts.
