Safety Notes
2.6
Electrical connection
Observe the applicable national accident prevention guidelines when working on live
frequency inverters (e.g. BGV A3).
Electrical installation is to be carried out in compliance with pertinent regulations (e.g.
cable cross sections, fusing, protective conductor connection). Additional information is
contained in the documentation.
You will find notes on EMC-compliant installation, such as shielding, grounding, the
arrangement of filters and the routing of lines, in the documentation of the frequency
inverters. Always observe these instructions, even for frequency inverters bearing the
CE marking. The manufacturer of the system or machine is responsible for maintaining
the limits established by EMC legislation.
Protective measures and protection devices must comply with the regulations in force
(e.g. EN 60204 or EN 61800-5-1).
Required preventive measure: grounding the unit.
2.7
Safe disconnection
The unit meets all requirements for safe disconnection of power and electronic connec-
tions in accordance with EN 61800-5-1. All connected circuits must also satisfy the
requirements for safe disconnection.
2.8
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. Changes to frequency inverters using the operating software are
permitted.
Do not touch live components or power connections immediately after disconnecting the
frequency inverters from the supply voltage because there may still be some charged
capacitors. Note the respective 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 re-starting automatically. If, for safety reasons, this is not permitted for the
driven machine, disconnect the unit from the mains before correcting the fault.
