3.3 Power supply
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 packs which guarantee reliable electri-
cal 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
Damage to the device.
The voltage input of the motor unit has no special protec-
tion against overvoltage.
• Make sure that the permitted voltage tolerance is not
exceeded. The tolerance must also be observed directly
at the operating voltage connection of the MTR-DCI
(see Tab. 3/3).
• Install an external fuse in the DC supply in order to limit
the available current (see Tab. 3/4).
