The converter control board uses a large number of MOS (Metal Oxide
Semiconductor) which are highly sensitive to electrostatic charge.
To avoid any damages to the control board
•
wear an earthing strap and always handle the board by the extractors
•
make sure you are working on an earthen anti-static floor
•
use anti-static packing material only
Overspeed protection
If an overspeed protection is required, it must be provided by the motor manufacturer
as this function is not integrated in the drive
Proper installation
Inverter drives are components that are intended for installation within electrical
systems or machines. The inverter may not be commissioned or put into operation
until it has been established that the machine as a unit complies with the provisions
of the EC Machinery Directive (89/392/EEC) as well with the standard EN 60204
(Safety of machines).
If the frequency inverter is used for special applications the specific standards and
regulations for this environment must always be observed.
Repairs may only be carried out by authorized repair workshops. Unauthorized
opening and incorrect intervention could lead to physical injury or material damage.
The warranty provided by DANAHER-MOTION would thereby be void.
Responsibility
Electronic devices are fundamentally not fail-safe. The company setting up and/or
operating the machine or plant is itself responsible for ensuring that the drive is
rendered safe if the device fails.
The standard EN 60204-1/DIN VDE 0113 “Safety of machines”, in the section on
“Electrical equipment of machines”, stipulates safety requirements for electrical
controls. The requirements to comply with are intended to protect the integrity of
personnel and machines and to maintain the function capability of the machine or
plant. The function of an emergency off system does not necessarily have to cut the
power supply to the drive.
To protect against risk of injury, it may be more beneficial to maintain individual
drives in operation or to initiate specific safety sequences. The emergency stop
process may be assessed by means of a risk analysis of the machine or plant,
including the electrical equipment to EN 1050. Part of this analysis is determined by
the selection of the circuit category in accordance with prEN 954 “Safety of machines
– Safety related parts of controls”.
