ELECTRICAL CONNECTIONS
WARNING
– EXPLOSION HAZARD – Do not disconnect equipment unless power has been
removed or the area is known to be non-hazardous.
WARNING – EXPLOSION HAZARD – Substitution of any components may impair suitability for
Class I, Division 2.
WARNING – EXPLOSION HAZARD – The area must be known to be non-hazardous before
servicing/replacing the unit and before installing.
Carrier terminals can accommodate 16
– 26 AWG (1.31 – 0.13mm
2
) solid or stranded wire with a
minimum temperature rating of 85
o
C. Input wiring may be shielded or unshielded type
(twisted pair or shielded twisted pair input wiring is recommended). Strip back wire insulation
0.25-inch on each lead and insert the wire ends into the cage-clamp terminal block connector.
Use a screwdriver to tighten the screw by turning it clockwise to secure the wire (use 0.22-
0.25nM torque). Since common mode voltages can exist on I/O wiring, adequate wire
insulation should be used and proper wiring practices followed. As a rule, input wires are
normally separated from power, output, and relay wiring for safety and isolation support, as
well as for low noise pickup.
