PORTABLE APPLIANCE TESTING
Please Note:
During testing of the machine with a portable appliance tester the insulation test will
show a failure due to the fitting of two VDRs between Live/Earth and Neutral/Earth.
These components have been fitted to safeguard against high voltage surges that may
occur on the mains supply to the machine and to comply with the EMC regulations.
To conduct an insulation test on this machine, the VDRs must be isolated from the
circuit first.
Ensure that the VDRs are reconnected after the insulation test has been completed and
before the machine is placed back into service.
The VDRs used have been specified and tested as safety critical components.
