Chapter 3 Setting Preparations
1. Make sure that the connection to [LINE IN] is correct.
2. Make connections to S10, S12 and S13 to prepare for a leakage current test.
Example: Connecting S10 terminal to functional earth terminal

If the wrong connection has been made to [LINE IN], the E terminal may
output the power supply voltage. Since there is then a risk of electric
shock, make sure that the [LINE IN] connection is correct before making
connections to the S10, S12 and S13 terminals.

tem for measurement
S12 terminal
For testing connection of patient connections to ground of power supply system
for measurement
S13 terminal For testing connection of metal accessible part not protectively earthed to ground
S10 terminal and
functional earth terminal
• S10, S12 and S13 are internally connected to the [LINE IN] E terminal (E ter-
minal is permanently connected to the [LINE IN] E terminal) and correct mea-
surements are not possible unless a power supply is connected to [LINE IN].
• When you do not know whether the S10, S12 or S13 terminal should be used,
refer to the documentation supplied with the equipment under test.
