7070iX TRO Analyzer
Connecting AC Mains Power
to the Orion 7070iX TRO
Analyzer
Wiring Requirements:
The Orion 7070iX Total Residual Oxidant Analyzer is designed
to be permanently wired to the AC Mains power.
An external, dedicated Power Switch or Circuit Breaker/
disconnecting device with an integrated Power Switch, must
be located within reach of the TRO Analyzer. This is to
facilitate safe removal of power for service and maintenance
of the Analyzer or removal of power in case of an emergency.
The Analyzer operates over AC Mains Power range of
100 VAC to 240 VAC, 50/60 Hz nominal. Maximum allowable
Mains Power fluctuations is +/- 10% and Maximum Current
requirement is 0.4 A. Insure that the AC Mains power source
meets these requirements before connecting the Analyzer to
the Mains power source.
All wiring to the TRO Analyzer must be made in accordance
with current National & Local electrical codes and safety
regulations. Wiring is to be performed by a licensed
Electrician.
A Class A GFCI (Ground Fault Circuit Interrupt) circuit breaker,
with appropriate Voltage and Current rating is recommended
where in accordance with local codes.
The power cable to the TRO Analyzer is supplied by the
customer. A certified 3 conductor 14 AWG power cord with
appropriate voltage, current and temperature rating is
recommended. The power cable must be compliant with local
code.
Use of a grounded conduit for the power cable is
recommended.
Connecting Power to the
Orion 7070iX TRO Analyzer
Remove the Electronics Enclosure cover
(Refer to Figure 8)
.
Locate and remove the AC Power Safety cover to access the
AC Power Terminal block
(refer to Figure 6)
.
Do not disturb
the factory installed wiring on the right side of the AC Power
Terminal block.
Pass the Power cable through the outer and inner Liquid tight
cable fitting located on the upper left side of the Analyzer
enclosure. Strip approximately 3.5" of the outer jacket from
the power cable end. Cut the inner wires so that the ground
wire is 1.5" longer than the hot and neutral wires. Strip
insulation on all three wire ends at 0.375".
Locate the AC Power Terminal block. (Mounted on the DIN
Rail - Refer to
Figure 6
&
Figure 7
). Insert the Line/AC HOT
wire into the terminal labeled L AC HOT. This is the terminal
with the internal fuse. (The terminal may need to be opened
by turning the terminal screw counter clockwise before
inserting the wire into the terminal). Tighten the locking screw
for this terminal and check that the wire is firmly connected to
the terminal block.
Insert the Neutral wire into the terminal labeled N AC Neutral.
Tighten the locking screw for this terminal and check that the
wire is firmly connected to the terminal block.
Insert the Ground wire into the Ground lug terminal labeled
G GROUND WIRE. Tighten the locking screw for this terminal
and check that the wire is firmly connected to the ground
terminal.
Insure that the wire loop on the ground wire is longer than the
Neutral and Hot wire loops
(refer to Figure 6
).
WARNING:
The Requirements and Instructions
described in this section must be carefully
followed to insure safe connection and operation
of the 7070iX TRO Analyzer.
WARNING:
Wiring is to be performed by a
licensed Electrician
WARNING:
Refer to
Figure 6
for details of the
power wiring connections before Connecting
Power to the Orion 7070iX TRO Analyzer.
WARNING:
Insure that the AC Mains Power is
OFF
, prior to making any connections between
the Mains power source and the Analyzer.
