14 Important Notes
Power from SELV/PELV power supply only!
All field signals and field supplies connected to this XTR I/O module
(750-677/040-000) 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 touch hot surfaces!
The surface of the housing can become hot during operation. If the device was
operated at high ambient temperatures, allow it to cool off before touching it.
System supply only with appropriate fuse protection!
Without overcurrent protection, the electronics can be damaged.
For 24 V system supply input voltage an external fuse, rated max. 2 A, slow
acting, min. 30 VDC shall be used.
Field supply only with appropriate fuse protection!
Without overcurrent protection, the electronics can be damaged.
For 24V field supply input voltage an external fuse, rated max. 10 A, slow acting,
min. 30 VDC shall be used.
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.
