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, 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 current
input to be wired to TB1, and voltage input wired to TB2, but only one input may
drive the output. 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.
Important – End Stops: For hazardous location installations (Class I,
Division 2 or ATEX / IECEx Zone 2), it should utilize two end stops (like Acromag
1027‐222) to help secure modules to the DIN rail (not shown).
