Safety notes
Transport and storage
The level of physical shocks and vibration during transport and storage must correspond to
class 2M3 according to EN 60721-3-2. It is important that the equipment is protected from
water (rainfall) and excessive temperatures.
Installation and Commissioning
Wherever faults occurring in the control equipment can lead to substantial material damage
or even grievous bodily injury (that is, potentially dangerous faults), additional external
precautions must be taken or facilities provided to ensure or enforce safe operation, even
when a fault occurs (e.g. independent limit switches, mechanical interlocks, etc.).
Operation
Emergency Stop facilities according to EN 60204, IEC 204 (VDE 0113) must remain
operative in all operating modes of the control equipment. Any disengagement of the
Emergency Stop facility must not lead to an uncontrolled or an undefined restart of the
equipment.
Filtered drives can only be used on power systems with grounded starpoint.
This equipment is suitable for use in a power system up to 10,000 symmetrical amperes
(rms), for the maximum rated voltage + 10 % when protected by an appropriate standard
fuse (refer to the catalogue for the type of fuse).
Risk of fire, severe personal and property damage
If an unsuitable braking resistor is used, this could result in a fire and severely damage,
people, property and equipment. It is essential that not only the correct braking resistor is
used, but it is installed correctly according to the instructions delivered with the braking
resistor.
The temperature of braking resistors increases significantly during operation. For this
reason, avoid coming into direct contact with braking resistors. Maintain sufficient
clearances around the braking resistor and ensure that there is adequate ventilation.
