If you wish to verify the CF rating of the pump, then fill a beaker with normal (0.9%) saline solution and load the pump with a
syringe and tubing filled with normal saline. The saline-filled tubing should be in contact with the saline in the beaker. Place the
ground reference of the leakage current Analyzer in contact with the saline in the beaker and verify the leakage current in the
normal setting is less than 10 micro-amps. [This procedure is specified in IEC 60601-2-24, clause 19.]
Turn off pump and disconnect from safety analyzer.
WARNING: Safety Class II, Type CF Medical
Equipment:
The pump is listed as Safety Class II,
Type CF equipment. Protection against electrical
shock does not rely only upon basic insulation, but
instead relies on double or reinforced insulation. As
such, this equipment does not utilize a third wire
ground (earth ground).
Therefore, when doing line leakage test it is not nec -
essary to measure leakage in both the open ground
and closed ground setting. Nor is it necessary to
perform a ground resistance test.

c
1) Connect the AC power cord to the Safety Analyzer. Set Safety Analyzer to Line Leakage mode of
operation. Press ë to turn the pump on.
c 2) Enclosure Leakage - Using the ground reference probe of the Analyzer, make contact with the center
post of the DC input jack. Verify the leakage in the normal setting is less than 100 micro-amps [note,
this is equivalent to BF rating for this device].
c
3) Earth Leakage - Use the Safety Analyzer, to measure the leakage current flowing through the earth
conductor of the AC power cord.
Verify the leakage in the normal setting is less than 100 micro-amps [note, this is equivalent to BF
rating for this device].
If you wish to verify the CF rating of the pump, then fill a beaker with normal (0.9%) saline solution and load the pump with a
syringe and tubing filled with normal saline. The saline-filled tubing should be in contact with the saline in the beaker. Place the
ground reference of the leakage current Analyzer in contact with the saline in the beaker and verify the leakage current in both
the normal and reversed settings is less than 10 micro-amps. [This procedure is specified in IEC 60601-2-24, clause 19.]
Turn off pump and disconnect from Safety Analyzer.
WARNING: Safety Class II with functional earth,
Type CF Medical Equipment:
The pump is listed as
Safety Class II with functional earth, Type CF equip -
ment. Protection against electrical shock does not
rely only upon basic insulation, but instead relies on
double or reinforced insulation. As such, this equip -
ment utilizes a third wire ground (earth ground)
lead of the power cord as earth return for electro -
magnetic energy and does not serve as a safety func -
tion.
Therefore it is neither possible nor necessary to per -
form a ground resistance test.
