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 14-28 AWG (2.08-0.081mm
2
) solid or
stranded wire. Input wiring may be shielded or unshielded twisted type.
Ideally, output wires should be twisted pair. Strip back wire insulation 3/8-
inch on each lead and wrap the bare wire in a clockwise direction around
the terminal screw and below the SEMS washer. Tighten the screw to
secure the wire at a torque rating range of 0.226 to 0.282 N-m. Terminals
include wire loops for test clip attachment, or for redundant soldered wire
connection required for heavy shock and vibration applications. Since
common mode voltages can exist on signal wiring, adequate wire insulation
should be used, and proper wiring practices followed. Output wires are
normally separated from input wiring for safety, as well as for low noise
pickup. Cables and/or conductors in conduit must have a minimum
temperature rating of 110°C.
Sensor wires are passed up through the center of the transmitter and wire
directly to transmitter input terminals 2 and 3, as shown in the connection
drawings below. Observe proper polarity when making input connections.
•
Use Insulated or Non-Grounded Sensors Only
- Input is non-isolated.
Do not ground any input leads.
This transmitter has an ANSI/ISA Type 2 output in which the power and
output signal share the same two leads, and the transmitter has a floating
connection with respect to earth ground. In these applications, output wires
normally pass through the output channel on top of the transmitter and are
drawn through the egress path of the connection head. Connect a DC
power supply and load in series in the two-wire loop as shown in the
drawing below.
