SEASONAL SAFETY CHECK
1. Please clean the plug of power cord at least once a year. Too much dust on plug may cause the fire.
2. The following safety checks should be performed at least every 12 months by a qualified person who
has adequate training, knowledge, and practical experience to perform these tests. The data should be
recorded in an equipment log.
①. Inspect the equipment and accessories for mechanical and functional damage.
②. Inspect the safety relevant labels for legibility.
③. Inspect the fuse to verify compliance with rated current and breaking characteristics.
④. Verify that the device functions properly as described in the instructions for use.
⑤. Test the protection earth resistance according IEC 60601-1:1988 + A1:1991 + A2:1995: Limit
0.1Ω.
⑥. Test the earth leakage current according IEC 60601-1:1988 + A1:1991 + A2:1995: Limit: NC
500μA, SFC: 1000μA.
⑦. Test the enclosure leakage current according to IEC 60601-1:1988 + A1:1991 + A2:1995: Limit:
NC 100μA, SFC: 500μA.
⑧. Test the patient leakage current according IEC 60601-1:1988 + A1:1991 + A2:1995: Limit: for
a.c.: 100μA (BF), for d.c.: 10μA (BF).
⑨. Test the patient leakage current under single fault condition with mains voltage on the applied
part according IEC 60601-1:1988 + A1:1991 + A2:1995: Limit: for a.c.:500μA (BF), for d.c.: 50μA (BF).
⑩. According to the test methods of IEC 60601-1:1988 + A1:1991 + A2:1995, the patient leakage
current (net voltage should be added on the applied part) of the testing device must less than 5000μA.
