6.3 Requirements for power adapters and supply voltage
The drive amplifier's logic supply and power supply must be provided using power adapters
or supply voltage sources with safe extra low voltage in SELV/PELV design according
to IEC 60950 / EN 60204. Power adapters or supply voltage sources having only basic
installation are not permissible.
The use of unsuitable power adapters not in SELV/PELV design
can lead to dangerously high voltages in the event of a fault, which
could lead to dangerous electric shocks resulting in injuries
or death.
The drive amplifier can generate a voltage of up to 60 VDC at the power adapter terminals
for power supply when operating as a generator. The power adapter should be designed for
such operation. Otherwise suitable action must be taken to prevent feedback.
