ELECTRICAL CONNECTIONS
WARNING
–
EXPLOSION HAZARD
–
Do not disconnect equipment unless power has
been removed or the area is known to be non-hazardous.
WARNING
–

–
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
–
28 AWG (2.08
–
0.081mm
2
) 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. Terminals are pluggable and can be removed from their sockets by prying
outward from the top with a flat-head screwdriver blade. This model allows
thermocouples or low voltage inputs to be wired to TB1 and drivers separate
outputs. 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). Use adequate wire insulation and follow proper wiring practice, as
common mode voltages can exist on signal wiring. As a rule, output wires are
normally separated from input wiring for safety, as well as for low noise pickup.
