2.1.6 Avoid Un-intended Start
NB!
While the frequency converter is connected to mains, the motor can be started/stopped using digital commands, bus commands, references or via the
Local Control Panel.
•
Disconnect the frequency converter from mains whenever personal safety considerations make it necessary to avoid unintended start.
•
To avoid unintended start, always activate the [OFF] key before changing parameters.
•
Unless terminal 37 is turned off, an electronic fault, temporary overload, a fault in the mains supply, or lost motor connection may cause a
stopped motor to start.
2.1.7 IT Mains
IT mains
Do not connect frequency converters with RFI-filters to mains supplies with a voltage between phase and earth of more than 440 V
for 400 V converters and 760 V for 690 V converters.
For 400 V IT mains and delta earth (grounded leg), mains voltage may exceed 440 V between phase and earth.
For 690 V IT mains and delta earth (grounded leg), mains voltage may exceed 760 V between phase and earth.
Par. 14-50
RFI Filter
can be used to disconnect the internal RFI capacitors from the RFI filter to ground.
2.1.8 Disposal Instruction
Equipment containing electrical components must not be disposed of together with domestic waste.
It must be separately collected with electrical and electronic waste according to local and currently valid leg-
islation.
2.1.9 Safe Stop of the Frequency Converter (Optional)
For versions fitted with a Safe Stop terminal 37 input, the frequency converter can perform the safety function
Safe Torque Off
(As defined by draft CD
IEC 61800-5-2) or
Stop Category 0
(as defined in EN 60204-1).
It is designed and approved suitable for the requirements of Safety Category 3 in EN 954-1. This functionality is called Safe Stop. Prior to integration and
use of Safe Stop in an installation, a thorough risk analysis on the installation must be carried out in order to determine whether the Safe Stop functionality
and safety category are appropriate and sufficient. In order to install and use the Safe Stop function in accordance with the requirements of Safety
