Warning:
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 elec-
trical sensors or peripheral
devices. Failure to do so may
result in damage to equip-
ment and property, and/or
injury or loss of life.
Note:
Maximum wire size termina-
tion and torque rating:
• 0.0507 to 3.30 mm 2 (30 to
12 AWG) single-wire termi-
nation or two 1.31 mm 2 (16
AWG)
• 0.8 Nm (7.0 lb.-in.) torque
Note:
Adjacent terminals may be
labeled differently, depend-
ing on the model number.
Note:
To prevent damage to the
controller, do not connect
wires to unused terminals.
Note:
Maintain electrical isolation
between analog input 1, digi-
tal input-outputs, switched
dc/open collector outputs and
process outputs to prevent
ground loops.
Note:
The control output common
terminal and the digital com-
mon terminal are referenced
to different voltages and
must remain isolated.
