A ground fault monitor PCA2001-A1 must be used when the PT2001-A1 is
powered from a cabinet with a DC/ DC converter PCA2011-A1 or PCA2018-A1.
If the DC 24 V is used for other external devices, a 1 A fuse is required for each
device.
A PTO2009-A1 must be used to connect the PT2001-A1 with 2 separate DC 24 V
cables from one cabinet or different cabinets. Each DC 24 V cable requires a 1 A
fuse mounted in the cabinet.
The PT2001-A1 provides 2 Ethernet sockets at the rear of the housing. Always
connect port A (ETH A) with an Ethernet switch.
A redundant Ethernet connection can also be established by connecting socket
port B (ETH B) with an Ethernet switch. It can be the same switch or, for higher
redundancy, another Ethernet switch in the system. If the connection on port A
fails, the PT2001-A1 uses automatically port B for the communication.
