That's why our instruction manual begins with these recommendations:
− Operate the switchgear as prescribed for its intended purpose.
− Ensure that the technical data on the name plate and in the specification are not exceeded during operation of the switch-
gear.
− Only install the switchgear in enclosed rooms suitable for electrical equipment.
− With the aim of a smooth installation sequence and ensuring a high quality standard, have installation at site performed by
specially trained personnel or managed and supervised by the ABB Service Department.
− Ensure that installation, operation and maintenance are only performed by specialist electricians familiar with this manual.
− Comply in full with the legally recognized standards (IEC / DIN VDE), the connection conditions of the local electrical utility
and the applicable safety at work regulations.
− Follow the instructions in the documentation when performing any work on switching devices and switchgear.
− Keep all documentation accessible to all persons concerned with installation, operation and maintenance.
− The user's personnel bear unlimited responsibility in all matters affecting safety at work and the correct handling of the
switchgear in accordance with EN 50110 and national regulations.
− Always observe the five safety rules set out in EN 50110 on establishing and securing the off-circuit condition at the place
of work for the duration of work on the switchgear. Gas-insulated switchgear are notable for maximum safety, as the circuit-
breaker performs the earthing switch function in conjunction with the three position disconnector. The sequence of safety
rules therefore deviates from that proposed in the standard as follows:
