Personnel Responsibility
Potential Risks Affecting Personnel
This section addresses the appropriate actions to undertake when faced with
hazardous situations during or before service of the analyzer. It is not possible
to list all potential hazards within this document. The user is responsible for
identifying and mitigating any potential hazards present when servicing the
analyzer.
Mitigating risks
Refer to the instructions for each situation listed below to mitigate associated
risks.
Electrocution hazard
1. Shut off power at the main disconnect external to the analyzer.
2. Open enclosure door.
If service must be performed with power engaged:
1. Note any live electrical components and avoid any contact with
them.
2. Only use tools with a safety rating for protection against accidental
contact with voltage up to 1000V (IEC 900, ASTF-F1505-04, VDE
0682/201).
Explosion hazard
Any work in a hazardous area must be carefully controlled to avoid creating any
possible ignition sources (e.g., heat, arching, sparking, etc.). All tools must be
The safety of the analyzer is the responsibility of the installer and
the organization he/she represents.
Technicians are expected to follow all safety protocols established
by the customer that are necessary for servicing the analyzer.
This may include, but is not limited to, lockout/tagout procedures,
toxic gas monitoring protocols, PPE requirements, hot work
permits and other precautions that address safety concerns
related to performing service on process equipment located in
hazardous areas.
Complete this action before performing any service that requires
working near the main input power or disconnecting any wiring or
other electrical components.

General Safety Information

appropriate for the area and hazards present. Electrical connections must not
be made or broken with power on (to avoid arching).
Electrostatic discharge
Use a damp cloth to clean the display and keypad to avoid static electricity
discharge.
Adhere to all warning labels to prevent damage to the unit. Refer to “Warning
Labels and Cautions” on page 2-1.

3 - EQUIPMENT INSTALLATION
The information in this chapter is related to safety during the equipment
installation.
Mounting the Analyzer
The OXY5500 is manufactured for wall installations. Depending on your
application and configuration, the analyzer will come mounted on a plate or
Unistrut®(or equivalent) metal frame. Refer to the OXY5500 Operator’s Manual
(P/N 4900002239) or the layout diagrams provided with the purchased
OXY5500 analyzer for detailed mounting dimensions.
Lifting/carrying the analyzer
At approximately 5.44 Kg (12 lbs) without sample conditioning system (SCS),
the OXY5500 can easily be lifted from the packaging and moved to the
installation location. Take care to lift or carry the analyzer by the enclosure and
not by any ancillary probes or cables, or damage may occur.
If the analyzer is configured with an optional integrated sample conditioning
system (SCS), two individuals may be required to lift and move the analyzer
system. Refer to the OXY5500 SCS Overview Manual (P/N 4900002244) for
more information.
Environmental Considerations
The analyzer should be mounted in an enclosure or, if outside, under a sun
shade to prevent direct sunlight exposure.
The analyzer shall not be mounted more than 2,000 meters above sea level.
Mounting brackets for equipment intended to be mounted on a
wall and/or part/s that support heavy loads shall withstand four
times the maximum static load.
When mounting the analyzer, be sure to position the instrument
so that it is not difficult to operate adjacent devices. Allow 1 meter
(three feet) of room in front of the analyzer and any switches.
It is critical to mount the analyzer so that the supply and return
lines reach the supply and return connections on the chassis,
while still maintaining flexibility, so that the sample lines are not
under excessive stress.

Opening/Closing the Analyzer Enclosure
Protective chassis and ground connections
Before applying any electrical signal or power, the protective and chassis
grounds must be connected.
Protective ground
•The protective ground (AWG and mm2), routed with the phase and
neutral wire, shall be equal or greater than the phase or neutral
wires.
•The protective ground shall be connected in such a way that it is
unlikely to be removed during servicing that does not require
disconnection of the protective conductor.
•The protective ground is the first wire to be connected to the analyzer
and the last one to be removed; its color can be either solid green or
green/yellow.
Chassis ground
•The chassis wire must be at least 6mm2.
•The chassis ground wire shall be connected to the rod or frame of the
shelter as soon as the protective ground wire is connected to the
instrument.
Hazardous voltage and risk of electric shock.Failure to
properly ground the analyzer may create a high-voltage shock
hazard.
Conduit seals or Ex e cable gland should be used where
appropriate in compliance with local regulations.
Apply 20 in-lbs of torque on each bolt to ensure the door is closed
properly to maintain required ingress protection.

Equipment Installation
Installation Safety Manual 3–3
Electrical Wiring Requirements
External Circuit Breaker Requirements
After installing all necessary conduit runs, make sure any remaining conduit
hubs, if installed with the Analyzer (Module 1) enclosure, are CSA and/or UL
Certified and rated Type 4X and/or IP66.
Interconnection of the analyzer enclosure shall be accomplished
using wiring methods approved for Class 1, Division 2 hazardous
locations as per the Canadian Electrical Code (CEC) Appendix J
and the National Electric Code (NEC) Article 501. The installer is
responsible for complying with all local installation codes.
Because the breaker in the customer-provided power distribution
panel or switch will be the primary means of disconnecting the
power from the analyzer, the power distribution panel should be
located in close proximity to the equipment and within easy reach
of the operator, or within 10 feet of the analyzer.
The customer-provided circuit breaker must be marked as the
disconnecting device for the analyzer. This switch or breaker shall
not interrupt the protective earth conductor.
The electrical installation to which the analyzer is connected must
be protected against transients. The protective device must be set
at a level not exceeding 140% of the peak rated voltage values at
the power supply terminals.
Thread lubricant must be applied on all conduit hub threaded
connections. SpectraSensors recommends using STL8 lubricant
on all conduit screw thread and it’s taped openings.
