A method of shutting down a pluggable electrical unit in a modular system comprising a base unit and at least one pluggable electrical unit connected via an interface. Each pluggable electrical unit has module electronics and a switch, which is coupled to a mechanical locking of the pluggable electrical unit in the base unit. The electronics is provided with a variable resistor, arranged in a feed line and is communicatively connected to the base unit via switching means. For removal, the pluggable electrical unit to be removed is unlocked and the switch is actuated. Then, communication operations in progress between the base unit and the pluggable electrical unit to be removed are terminated. The communication connection routed via the switching means is disconnected and the module electronics of the pluggable electrical unit to be removed are isolated from the base unit.
In a modular system comprising a base unit and one or more pluggable electrical units inserted and locked in said base unit, said base unit supplying electrical power to each of said one or more pluggable units inserted and locked in said base unit, a method of shutting down each of said one or more inserted and locked pluggable electrical units comprising:
