Safety Notes
2.7 Electrical connection
Observe the applicable national accident prevention guidelines when working on live
frequency inverters (e.g. BGV A3 for Germany).
During installation, observe the specifications regarding cable cross sections, fusing and
protective conductor connection.
Protective measures and protection devices must comply with the regulations in force
(e.g. EN 60204 or EN 61800-5-1).
– Grounding the unit is a necessary protective measure.
– Overcurrent protection devices are a necessary protective measure.
2.8 Safe disconnection
The MOVITRAC
®
LT units and their accessories meet all requirements for safe
disconnection of power and electronic connections in accordance with EN 61800-5-1.
All connected circuits must also satisfy the requirements for safe disconnection.
2.9 Startup / operation
Systems with integrated frequency inverters must be equipped with additional monitor-
ing and protection devices, as applicable, according to the relevant safety guidelines
and regulations, such as legislation governing technical equipment, accident prevention
regulations, etc.
Do not touch live components or power connections until 10 minutes after disconnecting
the frequency inverters from the supply voltage because there may still be some
charged capacitors. Observe the corresponding labels on the frequency inverter.
Keep all covers and doors closed during operation.
The fact that the status LED and other display elements are no longer illuminated does
not indicate that the unit has been disconnected from the mains and no longer carries
any voltage.
Mechanical blocking or safety functions inside the unit may result in the motor coming
to a standstill. Eliminating the cause of the problem or performing a reset may result in
the drive restarting automatically. If, for safety reasons, this is not permitted for the
driven machine, disconnect the unit from the supply system before correcting the error.
