Siemens SINAMICS S120 Equipment Manual page 10

Foreword
Correct and safe operation of SINAMICS S units assumes correct transportation in the
transportation packaging, correct long-term storage in the transport packaging, setup and
installation, as well as careful operation and maintenance.
The details in the catalogs and proposals also apply to the design of special equipment
versions.
In addition to the danger and warning information provided in the technical customer
documentation, the applicable national, local, and system-specific regulations and
requirements must be taken into account.
According to EN 61800-5-1 and UL 508 only safely isolated protective extra-low voltages of
the electronic modules may be connected to all connections and terminals.
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 19.4, 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 lead to incorrect operation.
