Power Jumper Contacts/Field Supply

Risk of injury due to sharp-edged blade contacts!
The blade contacts are sharp-edged. Handle the I/O module carefully to prevent
injury. Do not touch the blade contacts.
The I/O module 753-668/000-004 has 2 self-cleaning power jumper contacts that
supply and transmit power for the field side. The contacts on the left side of the
I/O module are designed as blade contacts and those on the right side as spring
contacts.

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.
