GT-600/GT-800 Instruction Manual

The tests should only be performed by competent persons who are familiar
with the requirements of the type of tests suitable for portable appliances.
It is potentially hazardous for both user and appliance should the wrong type
of tests be undertaken or if testing is carried out in an incorrect sequence.
It is important that you fully understand the various tests required and how
they should be performed.
The appliance must have passed the visual inspection, the protective bonding
resistance test (class I), and the insulation test (in this sequence) prior to any
other test. If any of these fail further testing must be stopped and any faults
must be rectified.
During the protective conductor current test, the touch current test and the
load test, the appliance will be energized at mains voltage. For this purpose,
switch on the appliance. Appliances driven by motors or equipped with
heating units may present a danger for the person testing (comply with the
appliance instruction manual!). Please ensure that the appliance is in a safe
condition to run and secure prior to testing.
Visual Inspection
Visually inspect the appliance before starting electrical tests.
Check the appliance for the following:
Condition of the appliance cables, i.e. no cuts, cracks or any physical damage
to the outer insulation layer.
Condition of the plug, cable securely attached, no signs of overheating and
that fitted fuses are correctly rated.
Any signs of damage, and that any mains or control switches will physically
switch on and off.
Any sockets for sign of overheating or physical damage.
