Electrical safety check

Recommended personnel: Electrical safety checks
should be performed by a trained bio-technician or
biomedical engineer.
Equipment and materials required: RENASYS™ power
cord, RENASYS power supply, electrical safety analyzer.
Note: When electrical safety check is performed, it
should be performed before functional checks.
Perform the following electrical safety checks IN THE
ORDER LISTED BELOW using the electrical safety
analyzer, in accordance with IEC 62353 for internally
powered medical electrical equipment with class I or
class II power supply.
Consult local/country requirements. If they are more
rigorous than the requirements of IEC 62353, follow
local/country requirements. (e.g. in Australia AS/NZS
3551 is applicable).
Power cord protective earth resistance check
(perform test only for class I power supply REF
66800161)
Note: For measurement of protective earth resistance,
test equipment must be able to deliver at least 200 mA
into 500 mΩ. Open circuit voltage must not exceed 24
volts.
Power cord acceptance criteria: electrical resistance
<100 mΩ
1.
Connect male end of power cord to electrical safety
analyzer outlet.

2.
Use probe of electrical safety analyzer to make firm
contact with middle ground wire of power cord.
Confirm electrical resistance is <100 mΩ.
Equipment leakage current check
1.
Equipment leakage current check shall only be
performed after the protective earth resistance
check has been passed.
2.
Connect female end of power cord to power supply,
and power supply to AC mains power. Connect
male end of power cord to electrical safety analyzer.
Use probe of electrical safety analyzer to make
firm contact with metal screw located in odor filter
door on base of device. Device does not have to be
turned on.
Note: Probe must touch metal.
3.
Test 1: Normal polarity (closed neutral, open
ground).
Acceptance criteria (device with class I power
supply REF 66800161 paired with appropriate power
cord): Max: 500μA.
Acceptance criteria (device with class II power
supply REF 66801558 paired with appropriate power
cord): Max: 100μA
4.
Test 2: Reversed polarity (closed neutral, open
ground).
Acceptance criteria (device with class I power
supply REF 66800161 paired with appropriate power
cord): Max: 500μA.
Acceptance criteria (device with class II power
supply REF 66801558 paired with appropriate power
cord): Max: 100μA

Note: Perform equipment leakage current check
in reverse polarity for per country requirements. If
electrical safety analyzer gives a printout, attach it to
RENASYS GO acceptance test record.
If required by your market, ensure a copy of electrical
safety test record remains with device so they are
shipped to the customer together.
Caution: Disconnect electrical safety analyzer before
proceeding to next check.
