Power cord for the United Kingdom
When using a GLC-9000 series current leakage tester in the United
Kingdom, make sure the power cord meets the following safety
instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:
Green/ Yellow:
Earth
Blue:
Neutral
Brown:
Live (Phase)
As the colours of the wires in main leads may not correspond with the
coloured marking identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth
terminal marked with either the letter E, the earth symbol or coloured
Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal which is
marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal
marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact
the supplier.
This cable/appliance should be protected by a suitably rated and approved
HBC mains fuse: refer to the rating information on the equipment and/or
user instructions for details. As a guide, a cable of 0.75mm2should be
protected by a 3A or 5A fuse. Larger conductors would normally require
13A types, depending on the connection method used.
Any exposed wiring from a cable, plug or connection that is engaged in a
live socket is extremely hazardous. If a cable or plug is deemed hazardous,
turn off the mains power and remove the cable, any fuses and fuse
assemblies. All hazardous wiring must be immediately destroyed and
replaced in accordance to the above standard.

OVERVIEW
This chapter describes the GLC-9000 in a nutshell, including the
main features, front and rear panel description, and the power up
sequence.
Introduction
Overview
Many electrical products must undergo electrical
safety testing to ensure their safety. These tests
include insulation resistance, withstand voltage,
ground continuity and leakage current tests. These
tests are complex and critical for safety standards
compliance.
To comply with international standards and to
ensure operator safety, leakage current tests are
also performed under normal and faulty operating
conditions.
Leakage current tests can be separated into 3 basic
types:
Earth Leakage current
Enclosure Leakage current
Patient Leakage current
The GLC-9000 complies with IEC, UL and other
international electrical safety standards requiring
leakage current measurement.

6. Patient
Auxiliary
Current

and a device during normal operation. This is not
intended to be perceptive. (Medical Equipment)
Measurement Principles
Background
Leakage current can be categorized into 3 types:
Electric current that flows through the body of
someone who touches the equipment, the current that
flows through a protective grounding wire to earth and
the current that flows through a human body
connected to an applied part. When testing the
leakage current of an EUT (equipment under test),
testing must be performed under normal and single
fault conditions.
As shown below, a number of relays are used to
simulate different fault conditions. Power to the EUT
is normally open and thus turning off the power
disconnects one wire on the power line.

GLC-9000 User Manual
16
Single Fault conditions include the following:
1. Earth disconnected (excluding earth leakage
current tests).
2. Disconnected neutral power line.
3. External equipment failure. (Patient leakage
current II, Patient Leakage Current III).
Polarity of the power supply can also be switched
to measure the leakage current under test. Thus
the polarity of the power supply should also be
taken into account.
Measurement
Methods
The diagram below shows how the probes, MD’s
and power supply are connected for different
leakage current tests.
Measuring Devices
Background
Leakage current (touch current) tests that measure
electrical equipment require a circuit network that can
simulate the impedance of a human body. The
impedance of a human body varies with the contact
points, area and the path of conduction. Thus the
circuit network used to simulate the impedance of a
human body varies with the type of test performed. As
such, the safety standards used to measure leakage
current also varies greatly. The circuit networks used
are known as measuring devices, or MD for short. MD

Note
When conducting leakage current tests, please note
the following:
1. Under normal operating conditions,
leakage current is measured when an electrical
device under test is properly insulated with earth.
If the device is not properly insulated, the leakage
current that is conducted through the
measurement network may be invalid.
2. Leakage current tests involve high
voltages. When working with high voltages,
testing personnel should use proper safety
precautions. All test labs should establish safety
rules to cut-off power to an EUT should conditions
become unsafe. Contacting any electrical appliance
under test is extremely hazardous and should not
be attempted.
3. The surrounding environment has an
effect upon leakage current tests. Avoid high
temperatures, high humidity and surface
pollutants on the enclosure surface as they can all
have an influence on the resulting data.
