WIRING CONNECTIONS AND CABLING
CAUTION To prevent possible signal degradation,
separate metal conduit runs are recommended
for the sensor, signal, and power wiring.
Under ideal conditions, the use of conduit and
shielded wire may not be required. However,
to avoid noise problems, power, signal, and
output wiring should be enclosed in separate
conduit. Just prior to entering the housing,
rigid conduit should be terminated and a
short length of flexible conduit should be
installed to reduce any stress to the housing.
Note: To maintain a NEMA 4X/IP65 rating, use approved
conduct connections or cord grips that have the same type
of ratings.
Power and signal wiring must bear a suitable
voltage rating, have a maximum temperature
rating of 75 C (167 F), and must be in
oo
accordance with all NEC requirements or
equivalent for the installation site. Use
either a standard three-prong grounded
flexible CSA certified line cord or equivalent
for power supply connection or hard wire
directly to the AC supply. If hard wiring the
AC power supply, use stranded, 14 AWG copper
conductor wire.
Signal wiring should not be run in the same
conduit or open trays where power wiring for
high amperage electrical equipment exists.
Ensure the final installation of signal and
power wiring prevents physical and/or
electrical interfere.
Note: Use weatherproof connections for all wiring ports.
Heyco RLTF ½" and LTF 9 cable grips are available through
ABB Inc.. See Section 17, Support Services.
The TB84PH Advantage Series analyzer accepts
wire sizes 12 to 24 AWG. Signal wiring should
always be twisted, shielded pairs to ensure
the best performance. Pin-style terminals are
recommended for all connections and available
as kits from the factory. See section 17,
Support Services, for more information.
