4.3 Electrical connections
Working with machinery controlled by a frequency converter requires special safety
precautions. These safety precautions depend on the kind of network used (TN, TT, IT
system). Consult Atlas Copco.
Most vacuum pump are designed for use in TT/TN networks and are intended for industrial
environments where the electrical supply is separated from the residential/commercial supply
network.
To use the machine in light industrial, commercial or residential environments with a shared
supply network or in an IT network, extra measures can be required: contact Atlas Copco.
