12 Important Notes
Only connect or disconnect lines when power is safely isolated!
The lines to the device can carry hazardous voltages and currents. Contact with
the lines when live can result in severe injury or death. Therefore, read and
observe the following safety rules before you perform work on the device:
1. Disconnect the respective system component from the power supply.
2. Secure the system component against unintentional restart.
3. Check if the voltage is positively isolated.
Power from SELV/PELV power supply only!
All field signals and field supplies connected to this I/O module (750-527) must
be powered from SELV/PELV power supply(s)!
Inadequate wire cross sections can cause temperature increases!
To avoid increasing thermal risks, only use conductor cross-sections sufficient for
the required maximum load current.
The conductor cross-sections specified in the technical data refer exclusively to
the mechanical connection capacity of the clamping points.
Do not exceed maximum values via power contacts!
The maximum current that can flow through the power jumper contacts is 10 A.
The power jumper contacts can be damaged and the permissible operating
temperature can be exceeded by higher current values.
When configuring the system, do not exceed the permissible maximum current
value. If there is a higher power requirement, you must use an additional supply
module to provide the field voltage.
