Safety information
Danger
Commissioning shall not start until you have ensured that the machine in which the
components described here are to be installed complies with Directive 98/37/EC.
SINAMICS S equipment must only be commissioned by suitably qualified personnel.
The personnel must take into account the information provided in the technical customer
documentation for the product, and be familiar with and observe the specified danger and
warning notices.
When electrical equipment and motors are operated, the electrical circuits automatically
conduct a dangerous voltage.
Dangerous mechanical movements may occur in the system during operation.
All work on the electrical system must be carried out when the system has been
disconnected from the power supply.
Danger
Correct and safe operation of SINAMICS S drive 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 protective extra-low voltages (PELVs) up to
30 V AC or 42.4 V DC may be connected to all connections and terminals.
Danger
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
industrial machines to EN 60204-1, Section 19.4, all connectors of SINAMICS equipment
must be disconnected/unplugged to prevent the equipment from being damaged.
Motors should be connected-up corresponding to the circuit diagram supplied with the motor
(refer to the connection examples, Motor Modules). They must not be connected directly to
the three-phase supply because this will damage them.
