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
EN60204−1.
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 24 V DC supply in order to
limit the available current (see Tab.3/4).
