Safety Information
In this instruction sheet a Warning identifies conditions and
actions that pose hazards to the user. A Caution identifies
conditions and actions that may damage the pressure
module or equipment under test. International symbols used
in this instruction sheet are identified later in the
Symbols
section. Read the entire instruction sheet and the 700PEx
CCD (Concept Control Drawing) before using the pressure
module.
In case of doubt (due to translation and/or printing errors)
refer to the original English instruction sheet.
XW
Warning
To avoid electric shock, injury, or damage to the
pressure module:
•
Use the pressure module only as described
in this instruction sheet and the Fluke
700PEx CCD (Concept Control Drawing)
otherwise the protection provided by the
pressure module may be impaired.
•
Inspect the pressure module before use. Do
not use it if it appears damaged.
•
Check the cable for damaged insulation. Do
not use the pressure module if the cable
appears damaged.
•
Never use the pressure module with the case
open. Opening the case invalidates Ex
Approval.
•
This equipment is specified for use in
measurement category I (CAT I) pollution
degree 2 environments and should not be
used in CAT II, CAT III, or CAT IV
environments. Voltage transients should not
exceed 300 volts for the CAT I applications
where this product is used. Measurement
transients are defined in IEC1010-1 as 2 µs
rise time with a 50 µs duration at 50 % of the
maximum amplitude height.
•
Measurement Category I (CAT I) is defined
for measurements performed on circuits not
directly connected to the mains.

Faults and Damage
If there is any reason to suspect that the safe operation of
the pressure module has been affected, it must be
immediately withdrawn from use and precautionary
measures must be taken to prevent any further use of the
pressure module in an Ex hazardous area.
XW
Warning
The safety features and integrity of the pressure module
may be compromised by any of the following:
•
External damage to the housing
•
Internal damage to the pressure module
•
Exposure to pressure loads in excess of the
maximum rated pressure
•
Incorrect storage of the unit
•
Damage sustained in transit
•
Correct certification is illegible
•
Functioning errors occur
•
Permitted limitations are exceeded
•
Functioning errors or obvious measurement
inaccuracies occur which prevent further
measurement by the pressure module
Safety Regulations
The use of the 700PEx pressure modules meets the
requirements of the regulations providing that the user
observes and applies the requirements as laid down in the
regulations and that incorrect use of the unit is avoided. Use
must be restricted to the specified application parameters.
Protecting Yourself from Pressure Releases
XW
Warning
•
To avoid injury due to the release of high
pressure, use only adapters and fittings
rated to withstand the appropriate pressure.
Ensure that all adapters and fittings are
securely connected.
•
To avoid a violent release of pressure in a
pressurized system, slowly bleed off the
pressure before you attach or remove the
pressure module from the pressure line.
•
When measuring the pressure of potentially
hazardous media, care must be taken to
minimize the possibility of leakage. Confirm
that all pressure connections are properly
sealed.
Avoiding Mechanical Damage
To avoid damaging the pressure modules, never apply more
than 10 ft.-lbf. of torque between the module fittings or
between the fittings and the body of the module. Figure 1
shows the correct way and incorrect ways to use a wrench
when applying torque to the pressure module fitting.
