3.3 Power supply
3.3.1 Power supply requirements
Warning
• To provide the electric power supply, use only PELV
circuits as per IEC/DIN EN 60204-1 (Protective Extra-Low
Voltage = PELV).
Take into account also the general requirements for
PELV circuits as per IEC/DIN EN 60204-1.
• Use only power sources which provide reliable electrical
isolation of the operating voltage as per IEC/
DIN EN 60204-1.
The use of PELV power units guarantees protection against
electric shock (protection against direct and indirect contact)
in accordance with IEC/DIN EN 60204-1 (Electrical Equipment
of Machines, General Requirements).
Caution
Device damage from overvoltage
The voltage inputs of the motor unit have no internal
protection against overvoltage.
• Make sure that the permitted voltage tolerance is not
exceeded. The tolerance must also be observed directly
at the operating voltage connections on the MTR-DCI
(see appendix A.1).
• Install external fuses (see Tab. 3/3).
