Risk of injury due to sharp-edged blade contacts!
The blade contacts are sharp-edged. Handle the I/O module carefully to prevent
injury.
The I/O module 750-555 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.
