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.
Wire terminals can accommodate 14–26 AWG (2.08–0.13mm
2
) solid or stranded
wire with a minimum temperature rating of 85
o
C. Input wiring may be shielded or
unshielded type. Ideally, output wires should be twisted pair. Terminals are
pluggable and can be removed from their sockets by prying outward from the top
with a flat-head screwdriver blade.
Strip back wire insulation 0.25-inch on each lead and insert the wire ends into the
cage clamp connector of the terminal block. Use a screwdriver to tighten the screw
by turning it in a clockwise direction to secure the wire (0.5-0.6Nm torque). Since
common mode voltages can exist on signal wiring, adequate wire insulation should
be used, and proper wiring practices followed. As a rule, output wires are normally
separated from input wiring for safety, as well as for low noise pickup.
