I-E67-84-1B February,2002 3-10
WARNING Disconnect the AC line cord or power lines
from the operating branch circuit coming from
the source before attempting electrical
connections. Instruments powered by AC line
voltage constitute a potential for personnel
injury due to electric shock.
WARNING Keep the enclosure and covers in place after
completing the wiring procedures and during
normal operation. Do not disconnect or
connect wiring or remove or insert printed
circuit boards unless power has been removed
and the flammable atmosphere is known NOT to
be present. These procedures are not
considered normal operation. The enclosure
prevents operator access to energized
components and to those that can cause
ignition capable arcs. Failure to follow
this warning can lead to unsafe conditions
that can injure personnel and damage
equipment.
The TB84PH Advantage Series analyzer does not
require pre-setting a jumper to accept
different line-power voltages. Power
connections are located in the back of the
instrument housing. The terminal block label
identifies all line power, output signal, and
sensor connections.
Notes:
1. ABB recommends installing a power line switch for
safety purposes and for providing power-up and power-down
convenience when servicing the analyzer.
2. Do not power the system from a transformer that also
powers large motor loads (over five horsepower) or any
other type of equipment that generates line voltage
surges, sags and excessive noise.
Using Figure 3-7 as a reference, make line
power connections as follows:
1) Strip wire insulation back approximately
0.250" (seven millimeters) to ensure the bare
wire will make good contact with the Insulated
Pin Lug terminals and will not be exposed
beyond the pin insulator.
2) Crimp Pin Lug terminals to wire using
Panaduit CT 570 or equivalent.
3) Connect the specified line voltage to
TB1-1 (Line - L1), the neutral to TB1-2
(Neutral - L2), and the ground to terminal
TB1-3 (Chassis Ground).
