If the following instructions are not complied with, there is direct danger
with the possible consequences of death or severe injury by electrical
current. Further, failure to comply can lead to destruction of the frequency
inverter and/or of the extension module.
When the frequency inverter is disconnected from power supply, the
mains, DC-link voltage and motor terminals may still be live for some
time. Wait for at least three minutes until the DC link capacitors have
discharged before starting to work at the unit.
equipment can withstand external voltage up to DC 30 V. Avoid higher
voltage levels. Higher voltages may destroy the module.
