    7.1 Primary circuits Under normal operating conditions (see Table 1) the ISM is maintenance free for a period of at least 30 years or until it has reached the permissible number of operating cycles. However when maintenance is carried out on the switchgear then the commissioning tests should be repeated. Check that the ISM is disconnected from all voltage sources before inspecting its insulating parts.

    7.2 Secondary circuits The CM is inherently maintenance free. However when maintenance is carried out on the switchgear then commissioning tests should be repeated. It is also recommended to conduct regular visual checks of the module housing and insulation of the wires connected to the CM. Test results should be treated as given in the Table 19.
