Siemens SINAMICS S120 Combi Equipment Manual page 11

Using protection against direct contact via DVC A (PELV) is only permissible in areas with
equipotential bonding and in dry rooms indoors. If these conditions are not fulfilled, other
protective measures against electric shock (e.g. protection through protective impedances
or limited voltage, or use of protection class I and II) must be used.
As part of routine tests, SINAMICS S components will undergo a voltage test in accordance
with EN 61800-5-1. Before the voltage test is performed on the electrical equipment of
machines to EN 60204-1, Section 18.4, all connections of SINAMICS units must be
disconnected/unplugged to prevent them from being damaged.
Motors should be connected up corresponding to the circuit diagram supplied with the
motor (refer to the connection examples of Motor Modules). They must not be connected
directly to the three-phase supply because this will damage them.
Operating the equipment in the immediate vicinity (< 1.8 m) of mobile telephones with a
transmitter power of > 1 W may cause the equipment to malfunction.
