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.
