5.3.5 General Warnings
Observe these general warnings when operating or servicing this
equipment:
•
Prior to operation of this equipment, personnel should read the
instruction manual thoroughly.
•
For systems installed in Class I, Division 2 areas, Power Entry and
Inputs/Outputs must be installed in accordance with Article
501.10(B)(1) of the National Electrical Code ANSI/NFPA 70:2005
.
•
For systems installed in Class I, Division 2 areas, Sensor Head
Cable must be installed in accordance with Article 501.10(B)(3) of
the National Electrical Code ANSI/NFPA 70:2005.
•
Only equipment rated for Class I, Division 2, Groups A, B, C, and
D should be installed in those areas. Verify the system rating on
the equipment labels (refer to Section 6.3 of this manual)
.
•
Use a damp cloth to wipe sensor band cover and transmitter when
installed in Class I, Division 2 areas to dissipate potential static
charge buildup.
WARNING
Using a dry cloth to clean the transmitter enclosure can cause
static discharge, which could result in an explosion in an
explosive atmosphere. Always use a damp cloth to clean the
transmitter enclosure.
•
If the sensor band was shipped with a sensor band shorting plug
installed on the sensor band to preamplifier cable connector,
ensure the sensor band shorting plug is installed on the sensor
band cable prior to installing sensor band. Sensors bands with an
‘R” in the Part Number suffix (e.g. Part #: 20686-26-R) do not
require a shorting plug.
•
As for any electrical equipment in Class I, Division 2 installations
wherein explosive atmospheres might be present, it is especially
important to de-power and remove the SONARtrac
TM meter from
service if its appearance or operating behavior indicates that it is
damaged or malfunctioning and/or that its safety features have
been otherwise compromised.
•
Trained personnel must carry out service on this equipment.
•
Follow all warnings on the unit and in the operating instructions.
•
This equipment is grounded through the grounding conductor of
the power cord.
•
Ensure all power cords, sensor to transmitter cable and signal
cables are properly routed to eliminate damage to them. Cable
conduit may be desirable to minimize potential damage.
