Communication Base Unit Wiring and Connections
Wiring and connections to the communication base units are performed according to the
following procedure.
System power supply wiring
Connect the 2 wires of the system power supply (24 Vdc) to terminals 7) (24 Vdc) and 9) (0 V) on
the communication base unit terminal block. And connect the ground wire to terminal 11) (GND)
on the communication base unit terminal block.
NOTICE:
Be careful of attaching or removing a terminal block.
After wiring, if a terminal block with live wires is removed, the exposed conductors on the rear
of the terminal block may cause of trouble.
Do not pass electricity through the I/O bus connector when it is exposed. Always connect
the I/O bus cable or a termination connector.
Otherwise possibility system power supply may short accidentally.
