SAFETY | 2.1 Basic safety instructions
2.1.2 Technical safety
During operation, electrical equipment and motors have parts and components with hazardous voltage levels, which
touched, can cause severe bodily injury or death.
All work on the electrical system must be carried out when the system has been disconnected from the power supply
(de-energized).
In combination with the drive system, the controllers are generally approved for operation on TN and TT systems
with a grounded neutral point.
During operation on IT systems, the occurrence of a first fault between an active part and the ground must be
signalled by a monitoring device. In accordance with HD 60364-4-41, it is recommended that the first fault be elimi-
nated as quickly as practically possible.
Operation in different networks is not permissible.
In systems with a grounded external conductor, an isolating transformer with grounded neutral point (secondary
side) must be connected between the mains and the drive system to protect the motor insulation from excessive
stress. The majority of TT systems have a grounded external conductor, so in this case an isolating transformer
must be used.
Flawless and safe operation of the controller assumes proper transportation in the transportation packaging, correct
long-term storage in the transport packaging, proper setup and installation, as well as careful operation and mainte-
nance.
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 also be taken into account.
To ensure compliance with EN 61800-5-1 and UL 508, only safety extra-low voltages may be connected to connec-
tions and terminals on the electronic modules.
Using protection against direct contact via DVC A (PELV) is only permissible in areas with potential equalization and
in dry rooms indoors. If these conditions are not fulfilled, then other protective measures against electric shock must
be taken (e.g. touch protection).
As part of routine material tests, the controller components will undergoes a voltage test in accordance with EN
61800-5-1. Before the voltage test is performed on the electrical equipment of machines acc. to EN 60204-1, Sec-
tion 19.4, all connectors of the controller component must be disconnected / unplugged to prevent the equipment
from being damaged.
Motors should be connected according to the wiring schematic supplied with the motor (refer to the connection
examples for motor modules). Direct connection to the three-phase supply is not permitted because it would
damage the motors.
Operating the equipment in the immediate vicinity (<1.8 m) of mobile telephones with a transmitter power of >1 W
may cause the components to malfunction.
