Appendix A Electrical Safety

Inspection

The following electrical safety tests are recommended as part of a comprehensive preventive maintenance program. They are a proven means of detecting abnormalities that, if undetected, could prove dangerous to either the patient or the operator. Additional tests may be required according to local regulations.

All tests can be performed using commercially available safety analyzer test equipment.

These procedures assume the use of a 601PRO

XL

International Safety Analyzer or equivalent safety analyzer. Other popular testers complying with IEC 60601-1 used in

Europe such as Fluke, Metron, or Gerb may require modifications to the procedure.

Follow the instructions of the analyzer manufacturer.

The consistent use of a safety analyzer as a routine step in closing a repair or upgrade is emphasized as a mandatory step if an approved agency status is to be maintained. The safety analyzer also proves to be an excellent troubleshooting tool to detect abnormalities of line voltage and grounding, as well as total current loads.

Protective Earth Resistance is measured using the RED test lead attached to the

DUT Protective Earth terminal or Protective Earth Metal enclosure or equipotential terminal. Select the test current by pressing SOFT KEY 3 to toggle between 1AMP,

10AMP, and 25AMP. The front panel outlet power is turned off for this test.

The following conditions apply: L1 and L2 Open.

TEST PROCEDURE

‹ Prepare

1) First select the test current that will be used for performing the Protective Earth

Resistance test by pressing AMPERES (SOFT KEY 3).

2) Connect the test lead(s) between the RED input jack and the GREEN input jack.

3) Press CAL LEADS. The 601PRO will measure the lead resistance, and if less than

0.150 Ohms, it will store the reading and subtract it from all earth resistance readings taken at the calibrated current.

4) If the calibration fails, the previously stored readings will be used until a passing calibration has occurred.

‹ Warning

During Earth Resistance testing, the DUT must be plugged into the 601PRO front outlet. If the DUT fails Earth Resistance, discontinue tests and label the device defective.

‹ Perform Test

1) From the MAIN MENU, or with the outlet unpowered, plug the DUT into the 601PRO front panel outlet.
