FOR UNITED KINGDOM ONLY
NOTE: This lead/appliance must only be wired by competent
persons.
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are colo ured in a cco r da n c e
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 colours 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 the letter E or by the earth
symbol
or coloured Green or Green & Yellow.
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,
cable of 0.75mm
2
should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the
connection method used.
Any moulded mains connector that requires removal
/replacement must be destroyed by removal of any fuse & fuse
carrier and disposed of immediately, as a plug with bared wires
is hazardous if a engaged in live socket. Any re-wiring mu st be
carried out in accordance with the information detailed on this
label.
The wire which is coloured Blue must be connected to the
terminal which is marked with the letter N or coloured Blue or
Black.

1. PRODUCT INTRODUCTION
1-1. Description
The GPT/GPI-700A series Electrical Safety Testers (EST) are
designed for AD/DC Withstanding Voltage test, Insulation Resistance test
(IR) and Ground Bond test (GB) in order to provide a safe and accurate
test environment for the operator. With thoughtful design described in
1-2. Feature insures a safe operation of high voltage test and protect user
from hazardous impact. Besides, the series can be used together with
scanner box of HSB-001-1 & HSB-001-2.
The Electrical Safety Testers comply with the requirement of the
electrical equipment & appliance control ordinances and JIS, CSA, UL,
BS and other overseas standards as well. The testers can be used for
withstanding voltage test of the various types of electrical and equipment
and components.
The GPT/GPI-700A series are based on the family of GW
withstanding voltage tester including AC Withstanding Voltage test, DC
Withstanding Voltage test, Insulation Resistance test and Ground Bond
test (GB).
