General safety principles
Frequency converters also use dangerous voltage for their operation and control rotating
mechanical parts that can be dangerous. Protection of direct contact with PANV (for voltage
up to 60V according to EN61800-5-1) is allowed only in connected spaces and in dry indoor
spaces.
If these conditions are not met, other protective measures against electric shock must be
taken, such as protective insulation. In principle, every frequency converter must be
grounded. Since the leakage current of the inverter can be greater than 30mA AC, good
grounding is necessary. The minimum size of the protective conductor must comply with the
local safety conditions for equipment with high leakage currents.
Applications with anti-interference filters can only be connected to
power supplies with a neutral point.
Therefore, mount the frequency converter on a metal mounting plate. The mounting plate
must not be painted and must have good electrical conductivity. It is strictly forbidden to
disconnect from the network from the motor side if the inverter is running and the output
current is not equal to zero.
They must also comply with the general and regional provisions on installation and safety
for work on equipment with dangerous voltage (EN61800-5-1), as well as the relevant
provisions regarding the correct use of tools and personal protective equipment (PPE).
In all operating modes of the control devices, the emergency stop
device in accordance with EN 60204, IEC 204 (VDE 0113) must be
functional. The failure of the emergency shutdown device must not lead to an uncontrolled
or indefinite restart of the device. The use of radio devices (e.g. radios or mobile phones) in
the immediate vicinity of the device may disrupt the function of the safety devices.
