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 may accommodate 14

28 AWG (2.08

) solid or stranded
wire with a minimum temperature rating of 90
o
C. Input wiring may be shielded or
unshielded type. Ideally, output wires should be twisted pair, or shielded twisted
pair. Use insulated wire to keep channels isolated. Terminals are pluggable and can
be removed from their sockets by prying outward from the top with a flat-head
screwdriver blade. Input channels each have two input paths that support different
nominal ranges (for example, DT336 allows current input to be wired to TB1-1/TB3-
1, and voltage input wired to TB1-3/TB3-3). 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 (0.5-0.6 Nm torque). Use adequate wire insulation and follow
proper wiring practice, as common mode voltages can exist on signal wiring.
Generally, output wires are separated from input wires for safety, but this is equally
important for low noise pickup.
