System Leakage Current Measurement - Siemens ARCADIS Varic Replacement Instructions Manual

Installing the ON/OFF assembly

System leakage current measurement.

WARNING
WARNING
Perform the system leakage current measurement according to ARTD-002.731.17....
Observe the system leakage current measurement information in chapter 1 of these
instructions.
Document the measuring procedure.
The highest measured values must be documented and evaluated in the system leakage
current protocol. This value must not exceed the permissible leakage current values
according to DIN VDE 0751-1:2001-10, Table F.1, line "System leakage current for
devices according to remarks 1 and 3", of 2.5 mA.

Electrical voltage!
Non-compliance can lead to severe injuries and even death.
The system leakage current measurement may be performed on
systems of protection class I only after the ground wire test has
been passed.
Electrical voltage!
Non-compliance can lead to severe injuries and even death.
No housing parts of the system may be touched during the direct
measurement of the system leakage current (measuring
arrangement according to chapter 1/Fig. 3).
Access to the system by third parties must be prevented.
Evaluate the results by comparing the first measured value to the
corresponding values documented during preceding
maintenance procedures or safety checks.
A sudden or unexpected increase of the measured values may
indicate that a fault has occurred in the primary circuit of the
power supply (damaged insulation, damage caused by humidity,
defective interference suppressor, etc.) - even if the limit value of
2.5 mA is not exceeded.
Where DIN VDE 0751-1:2001-10 applies, the permissible system
leakage current limit value is 2.5 mA.
In addition, the national regulations must be observed.
