Warning:
ç
Use National Electric (NEC) or
other country-specific standard
wiring and safety practices when
wiring and connecting this con-
troller 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)
• 0.56 Nm (5.0 in-lb.) torque
Note:
Adjacent terminals may be la-
beled differently, depending on
the model number
.
Note:
To prevent damage to the con-
troller, do not connect wires to
unused terminals.
Note:
Maintain electrical isolation
between analog input 1, digital
input-outputs, switched dc/open
collector outputs and process
outputs to prevent ground loops.
