Since the unit is classified as an IT equipment, according to the IEE Code of Practice, the test can also
be performed with 20-200mA. If this method is not available, and a high current test is to be used
instead, a 8A or 10A test is also acceptable (a minimum of 1.5 times of the
unit’s
internal 5A fuse).
Always
connect the test lead (mains earth) to the metal chassis. DO NOT CONNECT to the connectors
of the rear panel (signal earth), because you may damage the unit beyond repair. This type of damage
is not covered
by warranty.
