Wire the POINT Guard I/O modules properly so that 24V DC line
does not touch the safety outputs accidentally or unintentionally.
•
Clear previous configuration data before connecting devices to the
network.
•
Set unique network node addresses before connecting devices to
the network.
•
Perform testing to confirm that device configuration and operation
