Warning:
Óç
Use National Electric (NEC) or other
country-specific standard wiring and
safety practices when wiring and
connecting this controller to a power
source and to electrical sensors or
peripheral devices. Failure to do so
may result in damage to equipment
and property, and/or injury or loss
of life.
Note:
Maximum wire size termination and
torque rating:
• 0.0507 to 3.30 mm 2 (30 to 12
AWG) single-wire termination or
two 1.31 mm 2 (16 AWG)
• 0.8 Nm (7.0 lb.-in.) torque
Note:
Adjacent terminals may be labeled
differently, depending on the model
number.
Note:
To prevent damage to the control-
ler, do not connect wires to unused
terminals.
Note:
Maintain electrical isolation be-
tween Analog Input 1, Digital I/O,
Switched dc/open collector outputs
and Process outputs to prevent
ground loops.
Note:
The control output common
terminal and the digital common
terminal are referenced to different
voltages and must remain isolated.
