3.3 Power supply
3.3.1 Power supply requirements
Warning
• In order 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 providing reliable electrical
isolation of the operating voltage as per IEC/DIN
EN 60204-1.
By the use of PELV power units, protection against electric
shock (protection against direct and indirect contact) is guar-
anteed 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. 3/4).
